NRCRI (2005) confirmed that ginger grows well in the rainforest region The schizogenous type of secretory duct originates in the intercalary meristem of the developing regions. No fibers are present enclosing these small bundles. It is delimited by the shell zone on the rhizome apices, which appears as an arc of narrow cells in median longitudinal section. Other Notes Images presented in this entry are examples and are not intended to be used as basis for setting specifications for quality control purposes. It has been used for thousands of years as a medicine for a multitude of ailments. The plant has narrow; lanceolate to linear-lanceolate, Between these fusiform initials, some cells show transverse divisions to form ray initials. status of research in the pharmacological activities of ginger. A quiescent center was present in all the three cases as indicated by the light stainability of its cells. Detection Method Saturated chamber; developing distance 70 mm from lower edge; relative humidity 33%, Reference see USP Dietary Supplements Compendium 2009-2010 (for additional documentation). The actively dividing and deeply staining central cylinder shows vascular connections with the rhizome vasculature. The bases of these tillers become enlarged and develop into the primary fingers. Pungent, spicy ginger root is one of traditional root herb of culinary and medicinal importance. fungi causing ginger rhizome rot in Brazil. PubMed: ...

The sieve tube elements are arranged end to end to form columns of sieve tubes. Ayurvedic name(s): ardraka (fresh rhizome); shunthi (dried rhizome)   Uses; Benefits; Cautions; Interactions; Other names; References; Uses. Rhizome enlargement in ginger is by the activity of three meristematic zones. More recently, Ravindran and colleagues investigated the developmental anatomy of rhizomes, oil cells, and associated aspects (Remashree et al., 1997; 1998, 1999; Ravindran, 1998). Phloem parenchyma: The phloem parenchymal cells are comparatively larger than the companion cells and smaller than normal cortical parenchymal cells. A pair of ligules is formed at the junction of leaves and sheath. ginger (..S,M. Abstract. Many scattered, collateral, closed vascular bundles are present, of which the greater number is seen in the inner cortical zone. 2016, 14 (1): 01-09 Phadungcharoen et al. Ginger also contains 0.25 to 3.0% volatile oil, which contains zingiberene, Citral, borneol. 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. The number of primary branches may be two, three, or four. 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). Within the bud, leaves have imbricate aestivation (Shah and Raju, 1975a). 014ging leaf consists of a leaf sheath, a ligule, and an elliptical—lanceolate blade. Ground sun-dried Jamaican ginger rhizome was treated with supercritical CO2 (density 0.415-0.775 g cm-3) over the pressure range 128-197 bar (1850-2850 psi) and temperature range of 50-65°C. A. A few axillary buds at the distal end of the branch remain dormant. In the first year, a green, erect reed like stem about 60 cm high grows from this rhizome. Anticlinal and periclinal divisions of these cells result in. 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. 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. They provided anatomical notes on 18 genera and some 70 species (Tomlinson, 1956). This could happen because of the diffusion of oil basipetally and radially; such oil particles are deposited in the cells and can be seen as black masses inside cells as well as in the intercellular space. Except for the first few nodes, all the nodes have axillary buds. Oil cells are present in the epidermis or just below the epidermis of the leaf, petiole, rhizome, and root. In ginger, all zones in the root apex are originated from a common group of initials. The ginger rhizome contains 60–70% carbohydrates, 3–8% crude fiber, 9% protein, 8% ash, 3–6% fatty oil and 2–3% volatile oil. Upright-growing shoots are produced from the tips of lateral rhizome branches. No need to register, buy now! The initiation of oil cells and formation of ducts occurs in the apical parts of shoots and roots and starts much before the initiation of vascular elements. Near the dome, cells take less stain because of their quiescent nature. However, the rhizome structure of ginger gives evidence of both primary and secondary growth having a well-developed endodermoidal layer and cambium. These variations were presented in a comparative study of ginger and three other species (Ravindran et al., 1998). as well as identifying the plant by characteristic tissue features. The leaf sheath is about 15 to 18 cm and lamina about 12 to 15 cm long. In the ginger rhizome, four to eight companion cells per sieve tube element are arranged in vertical lines with transverse end walls. Stationary Phase Stationary phase, i.e. In the present study, various concentrations of extract prepared from Z. zerumbet were screened for its activity against Pythium myriotylum. 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. Further separation of the bordering cells along the radial wall leads to widening of the duct lumen. 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. As a lifetime disorder, ulcerative colitis (UC) is an inflammatory bowel disease (IBD) that affects quality of life and also demands long-term interventions.
