Robert P. Patterson; C. David Raper; H. Douglass Gross PLANT PHYSIOLOGY 1979. doi:10.1104/pp.64.4.551

Other claims from this paper (10)

Intervention effect Leaf total electrochemical water potential of soybean fell to about -24 bars during a 4-day drying cycle, compared with control levels.
Intervention effect Leaf total electrochemical water potential of soybean recovered to control levels after rewatering.
Intervention effect Vegetative and reproductive growth of soybean were about equally suppressed by leaf moisture stress.
Intervention effect Leaf moisture stress reduced the rate of appearance and number of pods of soybean.
Intervention effect Dry matter accumulation in soybean plants and pods was unaffected by temperature.
Mechanism Yield potential of soybean is restricted by a decrease in number of pods or seed.
Association Specific nodule activity and energy charge of soybean nodules declined with leaf moisture potential.
Intervention effect Recovery of specific nodule activity lagged behind recovery of leaf moisture potential after rewatering in soybean.
Intervention effect Energy charge of soybean nodules recovered as rapidly as leaf moisture potential upon rewatering.
Association The delayed recovery of specific nodule activity in soybean appears unrelated to recovery of nodule energy charge.
