Abstract
Leafwater potentials less than −12 bars inhibited net photosynthesis of green panic, and suspended the normal decline of photosynthesis associated with leaf ageing, until the stress was relieved and active net photosynthesis recommenced. This suspension of photosynthetic decline occured at stress levels down to approximately −90 bars provided leaves did not die as a direct results of waterstress (as opposed to death associated with normal senescence). The photosynthetic mechanism was not permanently affected by these levels of stress and, after rewatering, surviving leaves attained rates greater than control leaves of the same chronological age but comparable with those of the same physiological age
