Establishment of regeneration system of kiwifruit seedlings.

The full and mature seeds of kiwifruit were germinated to obtain the seedlings,and the regeneration system was established by using the stems,petioles and leaves as explants. The results showed that:the concentration of GA3 which was appropriate to treat the seeds was 2.5 mg/L and the treatment time was 8 h;the medium was more suitable for seed germination;the stems and petioles was easier to dedifferentiation than leaves,however,the average emergence rate of leaves was the highest.
