| Abstract: | The changes of ultrastructure of somatic embryos induced from friable embryogenic callus before and after were observed in this experiment. Maturation on the medium with high mass concentration of sucrose (50 g·L -1 ) in Dimocarpus longan Lour. cv. Honghezi. The results showed that the cells of somatic embryos changed completely both in structure and metabolism after maturation. This study would be helpful to learn the mechanism of maturation and to optimize regeneration system of somatic embryos in longan. |
