Abstract
The seventh leaf-sheaths of rice plants grown in solution and treated with gibberellin were analyzed to examine their changes in the activities of various enzymes during period of growth, in comparison with that of the control plants. Phosphatase, alkalipyrophosphatase, acetylesterase, maltase, β-glucosidase, α-galactosidase, β-galactosidase, amylase, urease, dipeptidase, ascorbic acid oxidase, and catalase activities were decreased in extracts of sheaths on a fresh weight basis by treatment with gibberellin. Activities of peroxidase and invertase were markedly increased.
