Root Sheaths as an Adaptation to Soil Moisture Stress in Arid Zone Grassesdrical sand sheaths surrounding the shallow lateral roots. These roots also have an aerenchymatous outer cortex which disintegrates at maturity. Various functions have been proposed for the sand sheaths: evidence reviewed here suggests that they are primarily an adaptation to soil moisture stress.

Adaptations of the Photosynthetic Pigment System to Ecological Conditions with Respect to Water in Dm components, primarily chlorophylls have been studied (Virgin, 1965; Duysen, Freeman, 1974, 1976; Alberte et al., 1975; Alberte, Thornber, 1977). Only the total amount of carotenoids has been recorded (Duysen, Freeman, 1974, 1976; Spyropoulos, Mavrommatis, 1978) and there is no information availabl

Ways of Detecting Adaptive Responses of Cultivated Plants to Drought. An Agronomic Approachospheric evaporative demand and the stomatal control of transpiration while the rate of water absorption depends on both the availability of soil water and the extent of the root system. By definition, cells and tissues are regarded as water-deficient or water-stressed when their water potential fal

Influence of the Environment on Cold Hardening and Winter Survival of Forage and Cereal Species withyear these stresses reduce or destroy completely several crops on cultivated lands in several parts of the world (Weiser, 1970). For example, in the United States of America from 1963 to 1968, annual losses in crops due to cold stress reached 341 million dollars on 1.42 million hectares.
