Carbon Balance of Sorghum Plants during Osmotic Adjustment to Water Stress.
The daily (24-hour) carbon balances of whole sorghum plants (Sorghum bicolor L. Moench cv BTX616) were continuously measured throughout 15 days of water stress, followed by rewatering and 4 more days of measurements. The plants were grown under controlled environment conditions typical of warm, humid, sunny days. During the first 12 days, osmotic potentials decreased in parallel with decreased ...
متن کاملEvaluation of changes in the water relations, osmotic adjustment and stay- green of different genotypes of sorghum under post-flowering drought stress
To investigate the effects of drought stress on the water stress, osmotic adjustment and stay green of sorghum genotypes and their relationship with grain yield, a split-plot on randomized complete block design with three replications was conducted at the experimental field of Seed and Plant Improvement Institute, Karaj, Iran in 2015. The main factor was three treatments: control (irrigation af...
متن کاملGenetic analysis of osmotic adjustment in crop plants
Phenomenon of osmotic adjustment Land plants have been coping with water stress for some Plant water deficit is a component of several different 400 million years, ever since they first left the seas and stresses, including drought, salinity and low tempercolonized dry land (Thomas, 1997). Because land plants ature, which severely limit plant growth and crop experience constant fluctuations in ...
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...
