Abstract

Abstract: The embryo abortion rate of 30 excellent cultivars of Chinese jujube ( Zizyphus jujuba Mill . ) were investigated 30 days after fruit set . The results showed that , the high abortion cultivars with more than 75 % aborted embryo , the middle abortion cultivars with 25 % - 75 % aborted embryo and the light abortion cultivars with less than 25 % aborted embryo made up 53.4 % , 3.3 % and 43.3 %of the cultivars studied respectively. 10 - 70 days old embryos of Z. jujuba‘Dongzao’and‘Jinsifeng’etc were employed to study embryo culture system. There were 3 growth-styles of the young embryos after inoculated , i . e. , forming callus , multiplicating small leaf in the center of cotyledons and forming seedling directly. The measures improving embryo culture and transplant of seedling were also studied.

Key words: Chinese jujube, Embryo, Abortion, Tissue culture
