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...
متن کاملOsmotic 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...

this study was carried out in the general commission for scientific agricultural research (gcsar) at der ez zour agricultural research center, during 2009- 2010 growing seasons. the role of na+, k+, na+/k+, carbohydrates accumulation of leaves, and sugar content of roots on the osmotic adjustment was studied in 10 sugar beet genotypes (five were monogerms and five were multigerms), under salini...
متن کاملProline accumulation and the adaptation of cultured plant cells to water stress.
The transfer of cultured tomato cells (Lycopersicon esculentum cv VFNT-Cherry) to a low water potential environment resulted in an increased dry weight to fresh weight ratio accompanied by a rapid accumulation of proline. Proline content continued to increase as osmotic adjustment and growth occurred. The initial increase in proline concentration was accompanied by a drop in turgor. However, pr...
متن کاملCarbon 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 ...
