Studies on Acidification of Media by Avena Stem Segments in the Presence and Absence of Gibberellic Acid 1

Hebard, Frederick V.
RESUMO
The rate of acidification of media by Avena stem segments was studied with a titrimeter. GA3 increased this rate by an average of 17% if supplied to the segments 90 min prior to measurement. GA3 inhibited the rate by 15% if supplied 10 min prior to measurement. After 90 min incubation, stimulation of elongation had started; at 10 min, GA3 had not yet started to stimulate elongation in the segments.
