Abstract
Kinetin-induced expansion of lettuce (Lactuca sativa) cotyledons and inhibition of root are accompanied by parallel changes in protein nitrogen, However, during its inhibition of the longitudinal growth and water uptake of hypocotyl and pea (Pisum sativum) epicotyl sections kinetin markedly stimulates protein synthesis. Kinetin seems to separate auxin induced effects on protein synthesis and water uptake and indicates that water uptake and protein synthesis may not necessarily be correlated. In contrast to gibberellic acid, kinetin restricts in lettuce seedlings, the mobilization of nitrogen reserves from the cotyledons, and kinetin induced growth is accompanied by a high protein nitrogen/soluble-nitrogen ratio which is characteristic of growth in light Growth in light may be under the dominant control of kinins.This publication has 4 references indexed in Scilit:
