Table I. PM H+ ATPase activity.

The vanadate-sensitive ATP hydrolysis was measured in PMFs prepared from PGs incubated in hypo- (198 mm), iso- (298 mm), and hyperosmolar (398 mm mannitol) germination medium. The specific activity is given in nmol mg−1 min−1. Mean values ± sd (n = 3).

Mannitol Concentration Specific Activity Osmotic Treatment
mm nmol Pi mg−1 min−1
198 89.50 ± 19.92 Hypo
298 130.20 ± 7.35 Iso
398 164.29 ± 30.30 Hyper
