Abstract

Abstract

The use of a linear transducer for detecting the growth of soybean stems of plants undergoing and recovering from internal water stress was investigated. Continuous, simultaneous measurements indicate a close correspondence in the behavior of plant water stress, net photosynthesis and stem diameter. Plant water stress produces relatively large, transient changes in stem diameter which obscure the effect of water stress on real growth. The close correlation between changes in stem diameter, reflecting xylem tension, and leaf water stress indicates that the linear transducer would be useful for indicating changes in plant water stress.
