Inflorescence Initiation in Lolium Temulentum L. XIII. the Role of Gibberellins

Abstract

Both stem growth and flowering in plants exposed to 1 long day showed an increasing response to gibberellins with increase in the concentration of the injected solution, up to 12 X 10-4M. With plants in short days both responses were asymptotic or showed an optimum at 4 X 1O-4M, depending on the light intensity.
