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 ...

Carbon balance and water relations of sorghum exposed to salt and water stress.

The daily (24 hour) changes in carbon balance, water loss, and leaf area of whole sorghum plants (Sorghum bicolor L. Moench, cv BTX616) were measured under controlled environment conditions typical of warm, humid, sunny days. Plants were either (a) irrigated frequently with nutrient solution (osmotic potential -0.08 kilojoules per kilogram = -0.8 bar), (b) not irrigated for 15 days, (c) irrigat...

Evaluation 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...

Solutes contributing to osmotic adjustment in cultured plant cells adapted to water stress.

Osmotic adjustment was studied in cultured cells of tomato (Lycopersicon esculentum Mill cv VFNT-Cherry) adapted to different levels of external water potential ranging from -4 bar to -28 bar. The intracellular concentrations of reducing sugars, total free amino acids, proline, malate, citrate, quaternary ammonium compounds, K(+), NO(3) (-), Na(+), and Cl(-) increased with decreasing external w...

Osmotic Adjustment in Cotton (Gossypium hirsutum L.) Leaves and Roots in Response to Water Stress.

The relative magnitude of adjustment in osmotic potential (psi(s)) of water-stressed cotton (Gossypium hirsutum L.) leaves and roots was studied using plants raised in pots of sand and grown in a growth chamber. One and three water-stress preconditioning cycles were imposed by withholding water, and the subsequent adjustment in solute potential upon relief of the stress and complete rehydration...
