Abstract
The effect of CCC m controlling plant height during internode elongation and assimilate accumulation, during grain filling and at grain maturity, was investigated in plants growing under three temperature regimes. With increasing temperature the plants matured earlier and the maximum height achieved became smaller. The effectiveness of CCC in controlling internode elongation was reduced. Analysis of the distribution of 14C-labelled compounds assimilated as 14CO2 by the flag leaves after ear emergence, showed no difference between the control and CCC-treated plants. It is suggested that the early application of CCC has a limited effect on metabolism of the plant during grain filling.
