Abstract

Growth retardants, CCC, Amo-1618, Phosfon-D and B-995, applied during seed vernalization inhibited the ear development of winter wheat. CCC applied during green plant vernalization inhibited flowering, but it had no appreciable effect on the final stem length. The inhibition by CCC was reversed by foliar application of gibberellin. On the other hand, CCC applied after the vernalization period affected the final stem length but not flowering. The amount of endogenous gibberellin-like substance(s) was greater in the vernalized plant than in the non-vernalized plant. No gibberellin-like substance was detected in the CCC-treated plant. Endogenous gibberellin-like substance(s), whose biosynthesis is inhibited by some growth retardants, may play a part in the vernalization process in winter wheat.
