A Biometric Approach, Morpho-anatomical and physiological modification in some grasses from the Salt Range under salt stress, Medicinal Plants, Plant Biochemistry, Phytochemistry, Plant Nutrition, Currently working on breeding mungbean and chickpea genotypes for high seed yield through induced mutation and cross breeding. aquatic plants, and was adapted by the International Program of Biology (IPB). Earlier work was mainly focused on the use of morphological or physiological and molecular aspects for improved stress tolerance. 2008. single sclerenchymatous bundle sheath. Moreover, metaxylem and phloem areas were the, . 2002. sedges (Cyperaceae), with special reference to, combined submergence and salinity in the halophytic stem-, of Chenopodiaceae halophytes: Adaptive, ecological and. Marram grass and Cacti (xerophytes) Most plants have adaptations to conserve water. The results showed that anatomical sections of both shoots and roots of the studied herbs are adversely affected by oil refinery effluents contamination and showed various structural abnormalities. 1991. Ahmad and N. Naz. The presence of thickened epidermal cell area is consistent with the results of. In the rainy season, plants in the sun have a higher net photosynthetic rate than shaded plants, possible due to a higher sink demand (growth) and leaf acclimation. All rights reserved. Moreover, an intensive scleri, was recorded in this species at both sides, Stomatal area and density in bracts presented almost. Succulence is an adaptation to arid environments commonly found in Crassulacean acid metabolism (CAM) plants, including most Crassula species. This has been shown experimentally with exoderm and air canals. These observations were further correlated with various stress adaptation traits like yield under stress, in vitro screening, chlorophyll content, transpiration heating and cooling, molecular markers etc. Mechanical tissues are generally absent. The data, were subjected to analysis of variance for c, 2006) It is adapted to oligotrophic waters and an important. There is an urgent need to study the genetics of these stress adaptive traits using high throughput molecular markers to make them more useful for a higher magnitude of genetic gain. Especially plants found in very hot and dry conditions as water will evaporate very quickly so they have evolved many adaptations that enable them to live where water availability is very low and they are … Three moisture regimes were maintained during the experiment, i.e., 100%, 75% and 50% field capacity. stress-induced morphological and anatomical changes in plants. 112: 307-315, 1999 Journal of Plant Research 0 bv The Botanical Society of Japan 1999 Anatomical Adaptations to Xeric Conditions in Maihuenia (Cactaceae), a Relictual, Leaf-Bearing Cactus James D. Mauseth Department of Botany, The University of Texas, Austin, TX, 78713 U.S.A. a plant develops a diff erent adaptation. Kust, H.J. Microscopic diagnostic features are seen in the leaf blade and the exposed green portion of the stem Epidermal silica cells, characteristic of the Cyperaceae, occur in all species At the generic level, characters common to the species examined are free subepidermal fiber strands, radiate chlorenchyma, three bundle sheaths (middle endodermoid, inner, and outer chlorenchymatous), accessory vascular bundles, and large marginal bundles in the blade. Enhancing magnetic properties while attaining maximum resitivity. 18 In most plant cells the vacuole occupies 70–80% of the cell's volume, but in succulents this is around 90%.
