The synchronization of early somatic embryogenesis and somatic
embryogenesis at high frequency from embryogenic callus in litchi (Xiafanzhi) were
studied in this experiment. The results showed that the process of somatic embryogenesis of litchi could be regulated by controlling the concentrations of 2, 4-D on the medium.
Cotyledonary embryoids were induced at the high frequency of 100% from the
synchronized early embryogenic calli with the number of formed somatic embryoi...
