| Abstract: | The stimulative effect of K+ on the activity of granule-boundstarch synthetase was uniformly observed in the enzyme preparationsobtained from the root, leaf and stem of sweet potato plants.The stimulation of K+ was most marked with the sweet potatoenzyme, while the broad bean enzyme was also appreciably stimulated.The K+-effect was very small in the enzyme from rice, barleyand taro plants.
