2.4-dichlorophenoxyacetic acid (2.4-D) and (2-chloroethyl)-trimethylammonium chloride (CCC) inhibit chlorophyll synthesis and protochlorophyllide 652 regeneration in 6-8 day old barley leaves whilst having little effect on the rates of protochlorophyll 632 synthesis from exogenous Ξ΄-aminelevulinic a
CCC at concentrations of 10(-3) M and higher inhibits chlorophyll synthesis and (3)H-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
