microscopic character of ginger rhizome

Answer/Explanation: – ‘A’ shows the nodes of the rhizome of ginger. Abstract. However, intercropping ginger with 24074 maize plants per hectare produced ginger rhizome yield of 10.84 tonnes ha-1 which was significantly (P ≤ 0.05) comparable with highest rhizomes yields of 14.08 tonne sha-1 obtained in sole ginger crop (P≤ 0.05). The differentiation of procambial cells into vascular tissue takes place at different stages of rhizome growth. The procambial cells and the ground meristem cells divide and parenchyma as well as vascular tissues add thickness to the newly enhanced axillary bud. These bundles have only one to three vessels and a small phloem. It belongs to the family Zingberaceae cultivated all over tropical and subtropical countries. The above characteristics show their state of rest and are called the quiescent center. Ginger has distinct anatomical features compared to other species, such as the absence of periderm, short-lived functional cambium, the presence of xylem vessels with scalariform thickening, helical and scalar-iform type of xylem tracheids, scalariform perforation plate, outer bundles with a col-lenchymatous bundle sheath, and high frequency of oil cells. 1 lb Fresh Organic Ginger Root/Rhizome - Grown on our Herb Farm in Mississippi - USDA Certified Organic PJHerbal. The width of helical tracheids is less than that of scalariform tracheids. Introduction: Ginger (Zingiber officinale Rosc.) Rhizome rot of ginger incited by Pythium aphanidermatum (Edson.) Later the central cell disintegrates and the contents spill into the cavity thus formed (see Figure 2.7I). This cell continues to divide, forming four to eight cells. Derivatization reagent: Anisaldehyde reagent Preparation: 170 mL of ice-cooled methanol are mixed with 20 mL of acetic acid, 10 mL of sulfuric acid, and 1 mL of anisaldehyde. They measure 30 X 30 to 114 X 48 ^m. Periblem consists of the initials of the cortex extending from the hypodemis to the endodermis. The number of nodes in each rhizome branch varies. Phloem parenchyma: The phloem parenchymal cells are comparatively larger than the companion cells and smaller than normal cortical parenchymal cells. The buds on the secondary fingers in turn can develop into tertiary tillers and tertiary fingers. Under white light the chromatogram of the test solution shows three violet zones at Rf ~ 0.24, Rf ~ 0.27, and Rf ~ 0.29 corresponding to reference substance 6-gingerol, 8-gingerol and 10-gingerol. 1. The leaf sheath is about 15 to 18 cm and lamina about 12 to 15 cm long. The schizogenous type of secretory duct originates in the intercalary meristem of the developing regions. The meristematic zone: This zone is shaped like an arch surrounding the quiescent center on the sides of the root body. In longisection the quiescent center resembles an inverted cup. In between these cells, certain cells in the cortical zone are distinguishable from the rest by their large size, dense cytoplasm and prominent nucleus (see Figure 2.7A). So when a rhizome is cut soon after harvest, one may not encounter much cork tissue.) Such stages are noticed about 3,250 ^m from the shoot tip (Ravindran et al., 1998; Remashree et al., 1999). B. O. Desalu 1. Likewise, many buds become active during favorable conditions, each of which produces secondary or tertiary rhizomes. The branches (1-3cm length) arising from the rhizome are oblique to it and end in undeveloped buds or depressed scars. Phytomedicine 2007;14(2-3):123-128. Except for the first few nodes, all the nodes have axillary buds. The internodal length of the rhizome branches ranges 0.1 to 1.5 cm, and varies even in a single branch. In the present study, the effect of ginger (rhizome of Zingiber officinale Roscoe) volatile oil on a rat model of colitis was evaluated. The stele that forms the bulk of the rhizome consists of parenchymal cells similar to those of the cortex, with starch grains and oil globules and a large number of irregularly scattered vascular bundles. They provided anatomical notes on 18 genera and some 70 species (Tomlinson, 1956). The ginger rhizome contains 60–70% carbohydrates, 3–8% crude fiber, 9% protein, 8% ash, 3–6% fatty oil and 2–3% volatile oil. In the ginger rhizome, four to eight companion cells per sieve tube element are arranged in vertical lines with transverse end walls. They found that the structural organization of ginger root apex differs from that of other taxa (such as Curcuma, Elettaria, and Hedych-ium). Showing page 1. The secretion fills the duct in young stages, but the quantity becomes reduced gradually, and finally the ducts appear empty. In the first year, a green, erect reed like stem about 60 cm high grows from this rhizome. insects, animal faeces, mold, fungi, etc.) 515). The rhizome of ginger is buff colored with longitudinal striations or is fibrous with no cork. The nature of the shoot apex: Shah and Raju (1975b) investigated the nature of the shoot apex in ginger. Rhizomes are also called creeping rootstalks or just rootstalks. Protophloem differentiation precedes that of protoxylem. A. J. Olanrewaju 1,2*, J. O. Owolabi 1, S. Y. Olatunji 1, E. I. Oribamise 1, O. I. Omotuyi 3 and A. In ginger, development of sieve tube is pycnotic, similar to the second type of nuclear degeneration reported by Esau (1969) and Evert (1984). The outer surface of the rhizome was grey but inner yellow colour with bitter odour and fragrant aromatic odour (Figure.1). If more than one branch from the parent rhizome is responsible for the ultimate growth and development of the adult rhizome, the branches of the mature rhizome lie in the same plane (Shah and Raju, 1975a). The The fingerprint of the test solution is similar to that of the corresponding botanical reference sample. Present, Inflorescence and fruit - Pineapple Fruit, Physical and Emotional Benefits Of Aromatherapy, Turmeric Health Benefits and Culinary Uses. H. Darkening of cell contents and increase in vacuolation. This process that takes place in adjacent cells leads to the formation of a duct. Identification: Compare result with reference images. The cells composing this tissue vacuolate earlier than the outer cells of the cortex. The ginger plant, Zingiber officinale, has a biennial or perennial, creeping rhizome, and an annual stem, which rises two or three feet in height, is solid, cylindrical, erect, and enclosed in an imbricated membranous sheathing. The cells of the inner axial zone are vacuolated. The secondary wall thickening in the tracheids of ginger is of two types, scalariform and helical. Perennial plants having thick branching aromatic rhizomes and leafy reedlike stems. Tertiary finger (third-order branch). Procambial differentiation: The peripheral or flank meristem divides periclinally and produces parenchymal cells. is a well-known traditional medicinal plant used for therapeutic effects in both Unani and Ayurvedic System of Medicine. The phyllotaxy of the scale leaves on the rhizome and foliage leaves on the aerial stem is distichous, with an angle of divergence of about 180°. Sample Preparation Method Sample: Mix 1 g of powdered sample with 10 mL of methanol and sonicate for 10 minutes, then centrifuge or filter the solutions and use the supernatants / filtrates as test solutions. The rhizome (underground part of the stem) is the part commonly used as a spice. In the rhizome, oil cell initials are present in the meristematic region. This character combined with the response of these cells to stains such as pyronin-methyl green indicates that these cells are in a state of comparative repose and hence are not synthesizing nucleic acids (Pillai et al., 1961). The flank meristem is situated on either side of the central mother zone. The length of a sieve tube element varies from 57.5 to 103.8 fxm, the average being 76.8 fxm. The vascular bundles are collateral, closed, and scattered in the ground parenchyma. Cells of the pr2 zone show dense staining. E. Nuclear disintegration of central cell. Fig 2: Plant of Amomum compactum Soland ex. Two kinds of apices are found in ginger: (1) the apices are low dome and surrounded by either scale leaves or leaf bases, and (2) they are dome shaped and raised on an elongated axis. After storage, the residual … In transection, an endodermoidal layer is also visible during the development (Remashree et al., 1998; Ravindran et al., 1998). (1998), and Ravindran et al. The newly harvested ginger rhizome is yellow; it is called popularly "tender ginger" or "fresh ginger." Some cells of pr1 and pr2 (see Figure 2.7) showed dense stainability for C-RNA (cytoplasmic RNA). (1961) named this meristematic region columellogen. Three propagule sizes were tested (20, 30 and 40 g) and seven nitrogen levels (0, 40, … is widely used as spice and medicinal plant in folk and traditional medicines. What Can You Take To Boost Testosterone Levels, Natural Erectile Dysfunction Treatment System, The ginger plant is a herbaceous perennial grown as an annual crop. Additional weak zones may be present. (Source: Shah and Raju, 1975a.). Favorite Add to Pink torch ginger live Rhizome tropical plant exotic plant flower YeyBroms. Extractive values for ginger were recorded as alcohol 2.7% and water 2.1%, fresh and dried ginger rhizomes afforded, moisture content 72.63 ±0.09%, 10.03±0.09%, total ash 2.50 ±0.06%, 7.30±0.10%, acid insoluble ash 0.57±0.03%, 2.03±0.09%, and water soluble ash 1.23±0.03%, 3.87±0.09% respectively. Some of the cells are distinguishable from the rest by deeper stainability, smaller size, less or no vacuolation, and darkly stained nuclei. Ginger is a subterranean stem (rhizome) modified for the vegetative propagation and storage of food materials. Ultimately the vascular bundles are found scattered in parenchymal ground tissue. An empty cell or cells with distorted cytoplasm appear along the duct lumen. ab, axillary bud; as, aerial shoot; cr, central zone; lba, leaf base; lp1, lp2, leaf primordium; pr1, pr2, peripheral zone; rr, inner aerial zone; sr, seed rhizome; sz, shell zone. This ginger is more pungent but lacks the aroma of Jamaica ginger. Under the microscope it exhibits numerous starch grains varying greatly in form and size in the different varieties, being nearly spherical, ovoid, ellipsoidal or pear-shaped and frequently with a characteristic beak, usually -from 0.005 to 0.04 mm., occasionally from 0.045 to 0.06 mm. This page has been accessed 46,977 times. Use: Dip (time 0, speed 5), heat at 100C for 3 min. The early studies on the anatomy of ginger were carried out mainly by the pharmacog-nosists, and they concentrated on the officinal part, the rhizome, either dry or fresh (Futterer, 1896). The metaxylem vessel elements with wider lumens can be seen near the plerome dome. dried ginger rhizomes afforded, moisture content 72.63 ±0.09%, 10.03±0.09%, total ash 2.50 ±0.06%, 7.30±0.10%, acid insoluble ash 0.57±0.03%, 2.03±0.09%, and water soluble ash 1.23±0.03%, 3.87±0.09% respectively. This variety is most extensively used. Transec-tion of the rhizome reveals that the endodermoidal layer and the pericycle become meristematic and undergo periclinal and anticlinal divisions resulting in a group of root initials. body weight) for 8 weeks as well. Roots always develop just below the nodal region. A comprehensive survey on the anatomy of the plants belonging to Zingiberaceae was that of Solereder and Meyer (1930), in their classical work Systematische Anatomie der Monocotyledonen (Systematic Anatomy of the Monocotyledons). Oct 2, 2016 - Science Image of Ginger rhizome showing oil globules from PS MicroGraphs. Later the slime body disintegrates. The main axis developing from the apical bud, which is the first developing branch, has 7 to 15 nodes, which later. At the early stage of development, the slime body is present in the sieve tube, which appears to be amorphous but homogeneous. These primary branches arise on either side of the main axis. From either side of the mother rhizome, branches arise and they grow out and become the primary tillers (Figure 2.5). The terminal part of the rhizome or a … The endodermis is lined by a pericycle composed of a single row of thin-walled slightly tangentially elongated cells devoid of any starch grains. After confirming for the presence of fungal spores, isolation was done by tissue segment method … The rhizomes are carefully dug up with hard picks, washed and dried. The rhizome may be long and straight as in most species ofHedychium, it may also be branched as in Zingiber. PubMed:Protective effect of ginger volatile oil against acetic acid-induced colitis in rats: a light microscopic evaluation. The lysigenous type of duct formation is more frequent in the meristematic region, but occurs in mature parts too. As a lifetime disorder, ulcerative colitis (UC) is an inflammatory bowel disease (IBD) that affects quality of life and also demands long-term interventions. It is found in water grasses (typha). The losses estimated were to the tune of 50 per cent in the country (Joshi and Sharma, 1982). Such groups of cells can be identified by the plane of cell division. dium and formation of the leaf sheath on the opposite side. The sieve element passes through a "fragmented multinucleated stage," a unique feature in the ontogeny of the multinucleated sieve tubes as reported by Esau (1938). The cortical cells are heavily loaded with starch grains. Typical mode of growth pattern (nodes are represented by dark horizontal lines and dormant buds by a black spot). The following discussion is adapted from Pillai et al. A violet zone at Rf ~0.53 corresponding to 6-shogaol is present. A biochemical zonation is present at pr2 that shows deep staining for DNA. 2016, 14 (1): 01-09 Phadungcharoen et al. However, no information was available on the developmental anatomy. (a) Germinating bud appears from the eye of the stem tuber. The scattered vascular bundles are developing from the PTM or procambial cells. 5 out of 5 stars (800) 800 reviews $ 19.95. The shoot apex is 91 to 112 ^m in width and 134 to 167 ^m in height. (1961), Aiyer and Kolammal (1966), and Shah and Raju (1975b). The protoderm—periblem complex is located outside the plerome and is composed of a single tier of cells. Concurrent separation of the cells leads to the formation of an intercellular space bordered by parenchymal cells. Figure 6.2 The rhizome of ginger. What Is the Keto Diet and Should You Try It? No green fluorescent zone is seen at Rf ~ 0.51 (Sharp-leaf galangal fruit). In the shoot apex in all stages, a single layer of tunica occurs, showing only anticlinal divisions. At stage five, the apex is a low dome having 214 to 248 ^m height and 53 to 75 ^m width. 61. Find the perfect fresh ginger rhizome stock photo. The cells in this region are arranged in vertical superimposed files. They may vary from 18 to 32 ^m in length and 7 to 19 ^m in width. Histochemical studies indicated that Z. zerumbet has greater amount of fibers than the others. At the early stage of development they lack any apparent slit due to the overlapping of their margins. As a ginger plant grows further, several fleshy roots of indefinite growth are produced from the lower nodes of the mother ginger and primary fingers. This page was last modified on 26 May 2015, at 18:58. At a lower level in the rhizome from the shoot bud apex, the PTM can still be identified. During subsequent development of the rhizome apex the cells derived from the inner axial zone elongate and contribute to the pith. Figure 6.2 The rhizome of ginger. The rings, or helices, are arranged either in a loose or dense manner. Ginger root nutrition facts. Raju and Shah (1977) studied the root apices of ginger, mango ginger, and turmeric with azure B staining to localize DNA and RNA contents in order to identify the quiescent center. Ginger is a gnarled rhizome that adds a distinctive sharp bite to baked goods and savory foods. one rhizome are in regular order, which finally give rise to a complete rhizome (Figure 6.2). The apex at stage three measures 76 to 140 ^m in width, and 53 to 86 ^m in height and is dome shaped. Adventitious roots and lateral growing points emerge from the nodes of the rhizome stem.

Olanrewaju 1,2*, J. O. Owolabi 1, S. Y. Olatunji 1, E. I. Oribamise 1, O. I. Omotuyi 3 and A. The duct can be either articulated or nonarticulated, and becomes gradually filled up with the cell contents of the lysed cells. inflicting considerable quantitative and qualitative losses. Lawrence BM. Mother rhizome. However, the rhizome structure of ginger gives evidence of both primary and secondary growth having a well-developed endodermoidal layer and cambium. During vascular differentiation a few cells of this meristem develop into procambium. A few axillary buds at the distal end of the branch remain dormant. These roots are thicker, milky white in color, with few root hairs, and no lateral roots. Irrespective of the number of primary branches, the subsequent branches lie in the same plane, although alteration of this scheme is seen sometimes. (Source: Shah and Raju, 1975.). Uses; Benefits; Cautions; Interactions; Other names; References; Uses. The roots of ginger are of two types, fibrous and fleshy. We recommend that this character be regarded as one of the bases for the identification of the ginger rhizome. During further development, the vacuolation increases and the cytoplasm shrinks and appears like a thread along the wall. Ginger composes novel phytochemical compounds and holds a special place, even today, in many traditional Indian and Chinese medicines for its disease preventing and health promoting properties. (1961). Introduction Ginger (Zingiber officinale Rosc.) Once this axis becomes aerial, the subsequent growth of the rhizome is due to the development of the axillary buds situated above the first two to three nodes of the underground main axis. Simultaneously the primary tissues continue to become differentiated into new oil cells and reach the secretory stage. The rhizome pieces of Z. officinale were washed with tap water to remove soil and were made to 1–2 cm long pieces. In the present study, various concentrations of extract prepared from Z. zerumbet were screened for its activity against Pythium myriotylum. Chronic toxicity studies have not raised suspicion of other organ changes. Maton. A foliage. Crude aqueous extracts of ginger were gavaged at doses of 0. fungi causing ginger rhizome rot in Brazil. Oil cell mother cell. C. Two main axes developing from the seed rhizome, and their subsequent branches developing in the same plane. These vessels have a diameter varying from 21 to 66 ^m. The transection of a fresh, unpeeled rhizome is almost circular or oval, about 2 cm in diameter, with the outline almost regular. Ayurvedic name(s): ardraka (fresh rhizome); shunthi (dried rhizome)   The root tip can be distinguished into two zones on cytophysiological grounds: 1. The isodiametric cells at the very center of the plerome divide like a rib meristem to give rise to the pith. Such ‘rhizomes are called sobole rhizomes. To submit a suggestion or contribution, please contact Merle Zimmermann. The sieve tube elements are arranged end to end to form columns of sieve tubes. The plant is erect, has many fibrous roots, aerial shoots (pseudostem) with leaves, and the underground stem (rhizome). Scattered within the cortex are numerous oil cells that contain large globules of yellowish-green color. Shah and Raju (1975b) recognized seven developmental stages of the apical bud. Outside the plerome dome all cells of the periblem exhibit T-divisions initially but later in development show anticlinal divisions, and the endodermis is differentiated at that time. A few cells toward the flank showed increased concentrations of DNA as evidenced by dense staining. In species of e.g. View abstract. These ducts anastomose and appear branched in longitudinal section. The hypodermis arises from the inner layer of the protoderm—periblem initials. These are the procambial initials and each such group contains 15 to 20 cells. The development of a new rhizome is by the enhancement of a dormant axillary bud, which acts just like the main shoot apex. Division of mother cell. Infected rhizome of ginger showing water soaked lesion were collected from farmers’ field of Ri-Bhoi district in Meghalaya. These grains are large, simple, and ovoid, in length varying from 15 to 65 ^m. 2. B. O. Desalu 1 The root primordia are of the open type, having common initials for the cortical meristem, root cap, and protoderm. Inner to the cork is the cortex that is about 4 mm in thickness, composed of thin-walled large hexagonal to polygonal parenchymal cells. Africa and China. long and 3. cm thick (Fig. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. The pattern of rhizome branching is illustrated in Figure 2.6. In this stage the cells adjacent to the duct become storage cells, containing numerous starch grains and large vacuoles. The first sieve tube element can be distinguished at a distance of 720 to 920 ^m from the shoot apex. The cells are thin-walled and arranged in a biseriate manner. In general, xylem elements in Zingiber consist mainly of tracheids and rarely of vessels. It is sliced before drying. Once the lysogeny of the central cell is completed, the adjacent cells also lyse gradually in a basipetal manner, resulting in the widening of the duct lumen. They may vary from 18 to 32 ^m in length and 7 to 19 ^m in width. The rhizome is considered the most useful part of the plant. No green or reddish fluorescent zones are seen at Rf ~ 0.07 and 0.20 (Katsumada galangal semen (Alpinia katsumadai)). D. A main axis with four primary branches and their subsequent branches developing in the same plane. The actively dividing and deeply staining central cylinder shows vascular connections with the rhizome vasculature. Within this is the cork, varying in thickness from 480 to 640 ^m and differentiated into an outer region 300 to 400 ^m in thickness, composed of irregularly arranged, tangentially elongated, slightly brown-colored cells, and an inner zone of 6 to 12 regular rows of thin-walled rectangular to slightly tangential elongated cells arranged in radial rows. In the fresh state, it has a characteristic staghorn-like ap­pear­ance; dried ginger is usually sold in form of an off–white to very light brown powder. Normally, these roots originate from the lateral or opposite side of the axillary bud and scale leaf. In primary tissues the oil duct development is schizogenous, whereas further development proceeds both schizogenously and lysigenously. pylori Inhibition and Anti-Oxidative Mechanism. These scale leaves fall off or may be lost, so that in mature rhizomes only the scars remain. Pith cells differentiate in the inner axial zone (rr). In the underground stem the nodes have scale leaves that ensheath and protect the axillary buds. Secretory ducts are formed both schizogenously and lysigenously (Remashree et al., 1998; Ravindran et al., 1998). Subsequently the surrounding cells also enlarge in size, showing cytoplasmic and nuclear disconfigurations (see Figure 2.7E, F). Microscopic free-floating species, however, do not have rhizoids at all. The salient features are given in Table 2.1, which presents the important anatomical similarities and differences among the four species: Z. officinale, Z. roseum, Z. zerumbet, and Z. macrostachyum. The inner limit of the cortex is marked by a single-layered endodermis composed of thin-walled rectangular cells, much smaller than the cortical cells, with their radial walls slightly thickened and free from starch grains. Rhizome. In transections passing near the tip of the plerome dome, the initials can be distinguished as a compact mass of isodiametric cells surrounded by radiating rows of periblematic cells. Cyloplasmic vacuolation initiates in the oil cells at a distance of about 420 ^m from the shoot apex. Ginger plant (Zingiber officinale Rosco) is belonging to the family Zingiberaceae.It is one of the world’s most important spices and produces a pungent, aromatic rhizome. camphene and phellandrene. 1. B. Within the bud, leaves have imbricate aestivation (Shah and Raju, 1975a). 1. 014ging At the same time, the nucleus disintegrates and the cell assumes the features of the enucleated sieve tube element. Macroscopic Characteristics The main rhizome (round turmeric) is ovate or pear-shaped, up to 4 cm. Which of the following statements is true of ginger? Contents. Under white light no pink zone is seen at Rf ~ 0.64 (Kaempferia galangal rhizome). The cells arise by the activity of a meristem, which can be easily differentiated from the rest of the region.

Microscopic evaluation is indispensable in the initial iden-tification of herbs, as well as in identifying small fragments of crude or powdered herbs, and in the detection of adulterants (e.g. The aim of this study was to review the chemical composition and biological activities of Z. officinale (ginger) essential oil. Geographical source: ADVERTISEMENTS: Jamaica, South India (Cochin), Africa, Japan . Ginger (Zingiber officinale Rosc.) The root cap is not differentiated into columella and a peripheral zone, and hence there are no separate initials for these regions. Between 10-gingerol and 6-shogaol other weak zones are visible. These are the fibrous roots, and the number of such roots keeps on increasing with the growth of. 1 Bulletin of Health, Science and Technology BHST ISSN 0858-7531 Volume 14, Number 1, 2016 : 01-09 MICROSCOPIC INVESTIGATION OF CURCUMA PETIOLATA ROXB. Figure 2.3 Floral diagram of ginger flower. After planting, many roots having indefinite growth grow out of the base of the sprouts. ginger (..S,M. It is often called ginger root, or simply ginger. During the initial growth, the apical bud of the rhizome piece planted grows out and becomes the main tiller or mother tiller. (1) An inner system of ‘scattered’ vascular bundles which serial cinematography reveals to have an axial pattern conforming to the basic ‘palm’ configuration (a system of upwardly branching leaf traces with interconnections). There are four stages involved in its development: initiation, differentiation, secretion, and quiescence. This is darker and smaller than Cochin ginger. Source: PlantaPhile[7], Ginger Aerial Parts and Flower The helical bands are found joined in certain areas giving ladder-like thickening. During stage seven, the underground branch reaches the soil level. In the study conducted by Rosangkima et al., (2018), F.oxysporum, F. solani and Plectos-phaerella cucumerina were also iso-lated and identified from soft rot diseased ginger rhizomes. The present study focuses on the clastogenic effect of ginger rhizome. It sometimes begins to grow when kept in a damp atmosphere. The oil cell frequency was found to be 17.8/mm2 in ginger, whereas the corresponding frequency in the other species was 9.5, 5.3, and 2.8/mm2 in Z. zerumbet, Z. macrostachyum, and Z. roseum, respectively.
