Abstract:
The experiment was conducted at the University of Arizona Campus Agricultural Center to evaluate the effect of soil moisture stress on photosynthesis, transpiration, diffusive resistance, temperature differential, leaf temperature, and specific leaf weight of seven sorghum Sorghum bicolor (L.) Moench cytoplasms represented by nine lines. As soil moisture stress increased, diffusive resistance and leaf temperature increased whereas photosynthesis and transpiration decreased. Temperature differential was highest under high soil moisture stress and lowest under medium soil moisture stress. Specific leaf weight was highest under medium soil moisture stress. Three lines, AKS37, AKS38, and A2Tx398, representing two different germplasms under high soil moisture stress exhibited high photosynthesis and transpiration rates, high specific leaf weights, and low diffusive resistance. Differences in photosynthesis rates under non-soil moisture stress between A1 and A2 cytoplasmic sterility systems were significant.
