Measurements were made of corn and pepper plants under environmental stress. Soil water potential was measured by a thermocouple psychrometer located in the root zone of each plant. Leaf water potential was inferred by pressure bomb readings. Transpiration of corn was measured by weight change, and pepper by microchamber. Water potential and transpiration were determined during periods of light and darkness. Light period resistance appeared relatively constant, dark period resistance was almost 5 times that of the light period. Resistances for partial darkness were found to have a total plant resistance lying between the light and dark period resistances. (Author)
