By measuring the length, width, thickness, thousand grain weight, germination rate and other characteristics of Camptotheca acuminata seeds from 8 provenances, the differences of morphology, germination rate and geographical variation of C. acuminata seeds from different provenances were studied. The results showed that there were significant differences in seed length, width, thickness, thousand grain weight and germination rate among different seeds from 8 provenances (P<0.05); the variation range of germination rate was 23.6%~91.3% and the germination rate of seeds from Wenzhou city, Zhejiang province is the highest. The coef?cient variation of seeds from Duanzhou district, Zhaoqing city, Guangdong province is 16.28%. The coef?cient of variation of the germination rate is the largest which is 12.10%. The seed thickness was signi?cantly correlated with latitude, annual average temperature and frost free period (P<0.05); and 8 provenances could be divided into 3 groups by clustering. The differences in seed morphology and germination rate of different species re?ect the rich 投注app diversity of Camptotheca acuminata , which is an advantage to good seed selection and breeding.
