Abstract:
The ginkgo seeds from Guangdong Province have been honored in the world market because of their good flavor.The ginkgo trees bloom early,and the embryos of the seeds are too little to be seen by necked eyes when harvested.The variety feature and phenological character of the ginkgo were observed,and the effects of climatic factors and phenological character on the variety feature were analyzed.The variety feature such as early-mature,little embryo and good flavor was thought to be resulted from higher average temperature and accumulated temperature over 10℃ of the year in the producing area.The rationalization proposal about preservation the ginkgo seeds after harvest is suggested in this paper.
