Chloroplast acclimation to low osmotic potential

Abstract

Photosynthetic potential of isolated chloroplasts was investigated during in situ water deficits. An eight day stress cycle imposed on spinach plants reduced leaf ψw by 0.57MPa, and leaf ψπ by 0.50MPa, resulting in partial turgor maintenance during the stress cycle. Pressure/volume curves confirmed the occurrence of osmotic adjustment. Leaf ψπ depression… (More)
