Abstract
Effects of compounds that influenced cytosolic pH on the level of putrescine in detached rice leaves were examined. Permeant weak acids, isobutyric acid and propionic acid, increased the level of putrescine in detached rice leaves. Procaine and trisodium citrate, known to be permeant weak bases, on the other hand, decreased the level of putrescine. It seems possible that the level of putrescine in detached rice leaves is regulated by the cytosolic pH.
