Abstract
Simultaneous measurements of apparent photosynthesis, transpiration and leaf temperature were made on the lower surfaces of intact Gros Michel and Dwarf Cavendish banana leaves. Interrupting the vascular supply to such leaves by cutting, caused a temporary increase in the rates of photosynthesis and transpiration and a decrease in leaf temperature. In young plants these phenomena were temporary, but in more mature plants having thick succulent pseudostems, these stimulations persisted for increasing lengths of time as more water storage tissue was included between the point of interruption and the leaf under measurement.
