Leaf senescence in a non-yellowing mutant of Festuca pratensis : III. Total acyl lipids of leaf tissue during senescence.

abstract：:1. Photosynthesis of leaf slices, mesophyll protoplasts, and intact chloroplasts of spinach was inhibited in hypertonic sorbitol solutions. Sorbitol could be replaced by other nonpenetrating osmotica such as sucrose or glycinebetaine. As a penetrating solute, ethyleneglycol was also inhibitory, but osmolarities requir...
