Abstract
CCC at concentrations of 10-3 M and higher inhibits chlorophyll synthesis and 3H-leucine incorporation into a protein fraction by barley leaf sections. Neither of these effects is reversed by exogenous GA3. No effect of CCC was observed on oxygen uptake by the leaf sections. The results indicate that high concentrations of CCC may act through an inhibition of protein synthesis, rather than through a direct effect on endogenous gibberellin production.
