Turgor-dependent unloading of photosynthates from coats of developing seed of Phaseolus vulgaris and Vicia faba. Turgor homeostasis and set points



Turgor-dependent unloading of photosynthates from coats of developing seed of Phaseolus vulgaris and Vicia faba. Turgor homeostasis and set points



Physiologia Plantarum 90(2): 367-377



Key physiological characteristics of turgor-dependent efflux of photosynthates were examined using excised coats and cotyledons of developing P. vulgaris Redland Pioneer and V. faba Coles Prolific seed during the linear phase of seed fill. Exposure to solutions of high osmotic potential inhibited net uptake of ucrose by cotyledons at developmental stages <60% of their final DW. The effect could not be fully reversed by transferring cotyledons to solutions with lower osmotic potentials.
