  • Through the study of the indexes of the proportion of seed weight in fresh fructification weight, length and width of the seed, oil content of seeds and thousand-grain weight of Prinsepia utilis Royle of different geographical provenances, the results showed that there were significant differences in the morphology and fresh fruit seed yield of different geographical provenances. The P. utilis seed had an oil content of 25% to 28%, and the thousand-grain weight of the seeds was 190 g~208 g.The temperature, altitude, rainfall and frost-free season of provenance were closely related to the indexes of proportion of seed weight in fresh fructification weight, length and width of the seed, thousand-grain weight and oil content of seeds.
