effect of drought stress on osmotic adjustment, proline and soluble sugars in root and shoot and relationship with drought tolerance in 12 genotypes of chickpea (cicer arietinum l.)
environmental stresses such as drought have important effects on plant growth and development. in order to evaluate the effect of drought tolerance, 12 chickpea genotypes were treated with drought stress in hydroponic condition in greenhouses. treatments were a control and two stress treatments -3 and -6 bar that was created with polyethylene glycol in hydroponic condition. two weeks after the ...
متن کاملMechanisms of Drought Resistance in Grain Legumes I: Osmotic Adjustment
When crops are exposed to drought there is commonly an increase in solute-pool of the plant tissue. A series of experiments were conducted in 1994 and 1995 in the University of Hohenheim, Germany, to evaluate whether drought-induced solute accumulation per se will improve drought resistance, to determine the species of active osmotica involved, and to identify alternative mechanisms in grain le...
متن کاملEffect of Drought in the Osmotic Adjustment of Cotton Plants
Water is crucial for crop growth and productivity. Cotton metabolism and yield are compromised under drought conditions, especially at flowering stage. Differences in drought tolerance exist among cultivars but the metabolic reasons for this that could be used to find traits for enhancing drought tolerance have not been clearly elucidated. Under drought stress, osmotic adjustment occurs in plan...
متن کاملOsmotic adjustment is a prime drought stress adaptive engine in support of plant production.
Osmotic adjustment (OA) and cellular compatible solute accumulation are widely recognized to have a role in plant adaptation to dehydration mainly through turgor maintenance and the protection of specific cellular functions by defined solutes. At the same time, there has been an ongoing trickle of skepticism in the literature about the role of OA in supporting crop yield under drought stress. C...
متن کاملMechanisms of drought response in Thuja occidentalis L. I. Water stress conditioning and osmotic adjustment.
We investigated the extent of osmotic adjustment and changes in transpiration rate that occur in response to repeated cycles of water deficit stress in 6-year-old Thuja occidentalis L. (eastern white cedar) trees. Groups of trees were water-stress conditioned by repeated exposure to predetermined thresholds of nonlethal water stress by withholding water until the predawn water potential fell to...
