Abstract

The polyembryony of Phoebe zhennan seeds was found through their anatomy. Observation was conolucted on the shape and position of the polyembryony seeds of Phoebe zhennan. Besides,analysis was made of the morphology and growth characters of generated seedlings. The results showed that its polyembryony rate was 12.4%. The shape and position of the embryos in seeds and growth characters of the seedlings with polyembryony in all the materials tested were very different. Somatic chromosome number of polyembryonic seedlings was 2n=24,and no change in chromosome number was observed.
