Abstract
Abstract The effect of auxin on the activities of amylase, cellulase, β‐1, 3‐ and/or β‐l, 6‐glucanase and hemieellulase were observed using etiolated barley coleoptile and pea epicotyl internode segments. The activities of β‐1, 3‐ and/or β‐l, 6‐glueanase and hemicellulase of barley were increased by indole‐3‐acetic acid in a 3 hours' treatment. Amylase activity was not influenced by the auxin. Cellulase activity was not detected under the experimental conditions. 2, 4‐Dichlorophenoxyacetic acid increased hemicellulase activity, but not cellulase and amylase activities, in pea epicotyl segments in 3 hours. Fungal β‐1, 3‐glucanase exogenously applied induced the elongation of barley coleoptile segments. The elongation induced by the enzyme was as high as that induced by indole‐3‐acetic acid at least for the first 1 to 3 hours.
