Abstract
Abstract The effects of abscisic acid (ABA) and K deficiency on leaf diffusive resistance were determined on soyabean (Glycine max L., cv. Amsoy 71) plants. Leaf diffusive resistance was measured on the lower surfaces of the primary leaves. Changes in leaf diffusive resistance, determined with the transient porometer, were found similar in both of the treatments compared with the control plants. 14C‐ABA (Abscisic acid) was given to roots of K‐deficient plants and specific radioactivities were found to increase in the primary leaves compared to K‐sufficient plants. Plants subjected to a K deficient stress induced through the roots were able to adapt to their environment by closing their stomata. This suggests that such adaptations are made possible by increasing the content of ABA in Key words: Glycine max Lcv.
