• Daucus carota tissues were grown on Murashige-Skoog medium (MS) at different concentrations with abscisic acid (ABA). Seven bands of chloroplast fractions were obtained on a sucrose gradient. At 10^<-5> M. ABA highly increased chlorophyll and protein nitrogen content of medium density chloroplasts. With increasing age of the tissues, the most active chloroplasts according to their ^<14>CO_2 fixation were found in smaller numbers. When treated with 10^<-5> M ABA, 34 day-old tissues cultivated in vitro showed the chloroplast pattern of 110 day-old tissues. The effect of ABA-given to the tissues during a short pretreatment or continuously present in the culture medium-on the ribulose diphosphate carboxylase activity was analysed. It was found that ABA at 10^<-5> M strongly inhibited ^<14>CO_2 fixation.
