摘要：
Transpiration, leaf temperature and stomatal resistance for a greenhouse cucumber crop were determined by simultaneously measuring solar radiation, air flow, transpiration rate, dew point, and air and leaf temperature profiles. Transpiration rate varied with solar radiation and was not uniformly distributed within the canopy. Leaf temperature was lower than air temperature on clear summer days owing to high transpiration rates. Stomatal resistance was computed and was exponentially related to solar energy. No significant correlations between stomatal resistance and other climatic variables were found. © 1990.
