microscopic character of ginger rhizome

It has been used for thousands of years as a medicine for a multitude of ailments. dium and formation of the leaf sheath on the opposite side. Optional: individually dissolve 0.5 mg each of 8-gingerol and 10-gingerol in 1 mL of methanol. The increase in size of the phloem element is proportional to the growth of the rhizome. becomes an aerial shoot. Lawrence BM. They may vary from 18 to 32 ^m in length and 7 to 19 ^m in width. G. Cytoplasmic condensation. A few cells toward the flank showed increased concentrations of DNA as evidenced by dense staining. The flesh of the ginger rhizome can be yellow, white or red in color, depending upon the variety. 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. The cells of the inner axial zone are vacuolated. In the ginger rhizome, four to eight companion cells per sieve tube element are arranged in vertical lines with transverse end walls. Likewise, many buds become active during favorable conditions, each of which produces secondary or tertiary rhizomes. An atmospheric pressure ion-source chamber enables us to analyze fresh samples with minimal loss of intrinsic water or volatile compounds. B—D. Source: Encyclopedia of Life http://eol.org/data_objects/24891510[9], Ginger Flower (Zingiber officinale) Mature oil duct with scanty cytoplasm (lc, lysing cell; n, nucleus; oc, oil cell; sd, secretory duct; s, starch grain; v, vacuole). one rhizome are in regular order, which finally give rise to a complete rhizome (Figure 6.2). The hypodermis arises from the inner layer of the protoderm—periblem initials. Young scale leaves have pointed tips that help in penetration of soil. Ginger (Zingiber officinale Rosc.) (a) Germinating bud appears from the eye of the stem tuber. The part of ginger that's used most often is the root. camphene and phellandrene. Near the dome, cells take less stain because of their quiescent nature. To submit a suggestion or contribution, please contact Merle Zimmermann. In the shoot apex in all stages, a single layer of tunica occurs, showing only anticlinal divisions. The buds on the secondary fingers in turn can develop into tertiary tillers and tertiary fingers. H. Darkening of cell contents and increase in vacuolation. Zingiber officinale Roscoe   Zingiberaceae   The axillary bud meristem is first discernible in the axillary position on adaxial sides of the third leaf primordium from the apical meristem as a distinct zone by the stainability of the constituent cells and multiplane division of the cells in the concerned peripheral meristem sectors. The third type is the secondary thickening meristem (STM), in which fusiform and ray initials are clearly visible. These stages occur between 1500 and 3000 ^m from the apex. Fig 2: Plant of Amomum compactum Soland ex. The rhizome is considered the most useful part of the plant. Mother rhizome. Figure 2.3 Floral diagram of ginger flower. 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. fungi causing ginger rhizome rot in Brazil. According to Stirling (2009), the major causes of post-harvest losses of ginger rhizome is decay or wet rot caused by What Is the Keto Diet and Should You Try It? This zone includes cells belonging to all the structural histogens of the root body (i.e., not structurally delimitable). These are the fibrous roots, and the number of such roots keeps on increasing with the growth of. It is a herbaceous perennial which grows annual pseudostems (false stems made of the rolled bases of leaves) about one meter tall bearing narrow leaf blades. (Source: Shah and Raju, 1975a.). In recent years quality of this ginger has improved. in the long diameter; sclerenchymatous fibers long, thin-walled, nonlignified, with oblique pores and distinctly undulate on one side; oil secretion cells with suberized walls and containing a light yellowish or yellowish-brown, oily substance; cork cells absent in the Jamaica variety. The vascular system in the underground rhizome of Alpinia speciosa L. (Zingiberaceae) is seen to be arranged in three distinct zones. Similar tracheids are present in Z. macrostachyum, whereas in Z. zerumbet and Z. roseum, only scalariform thickening occurs (Ravindran et al., 1998). Mother rhizome. 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. From either side of the mother rhizome, branches arise and they grow out and become the primary tillers (Figure 2.5). The root cap is not differentiated into columella and a peripheral zone, and hence there are no separate initials for these regions. A. Typical mode of growth pattern (nodes are represented by dark horizontal lines and dormant buds by a black spot). Shah and Raju (1975b) recognized seven developmental stages of the apical bud. Cultivation: The plant of ginger is a perennial herb about 1 metre high sympodial branching rhizome. They may vary from 18 to 32 ^m in length and 7 to 19 ^m in width. No fibers are present enclosing these small bundles. Macroscopic Characteristics 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 are thin-walled and arranged in a biseriate manner. Later a longitudinal slit is formed through which the shoot tip projects. These grains are large, simple, and ovoid, in length varying from 15 to 65 ^m. Irrespective of the number of primary branches, the subsequent branches lie in the same plane, although alteration of this scheme is seen sometimes. In the enclosing sheath of fibers the number of cells varies very much. Initiation and differentiation: In shoot apex, the meristematic cells are arranged in tiers. Many scattered, collateral, closed vascular bundles are present, of which the greater number is seen in the inner cortical zone. This variety is most extensively used. Zingiber officinale Rosc. The large bundles are partially or entirely enclosed in a sheath of septate fibers, whereas the smaller bundles are devoid of any fiber. one rhizome are in regular order, which finally give rise to a complete rhizome (Figure 6.2). Division of mother cell. Fig.1: Rhizome of Zingiber zerumbet (L) Smith. (1961) named this meristematic region columellogen. 50 ml/kg body weight) was administered by intraperitoneal injection to male mice. In certain cases these cells extend up to the base of the axillary buds. The experiments were conducted at the Teaching and Research Farm, Ladoke Akintola University of Technology, Ogbomoso, Nigeria in 2010 and 2011 to determine the effect of propagule size and nitrogen levels on the growth and rhizome yield of ginger. Such cells act as the oil cell mother cell. It also contains 50% starch, 2 to 3 % proteins and a small amount of sugar. Perennial plants having thick branching aromatic rhizomes and leafy reedlike stems. These vessels have a diameter varying from 21 to 66 ^m. Procambial differentiation: The peripheral or flank meristem divides periclinally and produces parenchymal cells. The rhizome may be long and straight as in most species ofHedychium, it may also be branched as in Zingiber. These steps are a gradual process that occurs acropetally (Figure 2.7). Specialists in Science Images. In the root body two histogens could be distinguished: (1) the plerome concerned with the formation of stele and (2) the protoderm—periblem complex concerned with the formation of the outer shell to the stele including periblem and dermatogen. The newly harvested ginger rhizome is yellow; it is called popularly "tender ginger" or "fresh ginger." 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 sieve tube elements are arranged end to end to form columns of sieve tubes. There are four stages involved in its development: initiation, differentiation, secretion, and quiescence. These fibers are very long, but less than 1 mm, have a diameter from 10 to 40 ^m, and are not straight, but undulate in character. The nature of the shoot apex: Shah and Raju (1975b) investigated the nature of the shoot apex in ginger. Ginger is the dried rhizome of Zingiber officinale, Roscoe (N.O. Anatomical Features of Ginger in Comparison with Related Taxa. The procambial cells and the ground meristem cells divide and parenchyma as well as vascular tissues add thickness to the newly enhanced axillary bud. In species of e.g. The peripheral zone (pr1) is concerned with the initiation of the next leaf primor-, Figure 2.8 Ontogeny of shoot apex: (A) dormant rhizome with stage 1 root apices; (B) rhizome with stage 2 shoot apex; (C) rhizome with stages 5, 6, and 7 root apices; (D) aerial apex showing topographical zonation; (E) rhizome apex showing topographical zonation. Such ‘rhizomes are called sobole rhizomes. During subsequent development of the rhizome apex the cells derived from the inner axial zone elongate and contribute to the pith. 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.
