摘　　要：对云南省鹤庆、丽江、剑川、兰坪、禄丰、寻甸、石林、昆明、沪西、沾益、师宗等11个地理种源的总花扁核木的出种率、种子大小(纵径×横径)、种子千粒质量、育苗发芽势、发芽率、幼苗苗高等指标的研究结果表明:不同地理种源的青刺果各项指标都有差异,同一地理种源的不同家系各项指标也有明显的变异。不同地理种源的果实出种率、种子千粒质量、种子的宽度与种源地温度关系密切,与其它地理因素相关性不大。Through the study on the idexes of the proportion of seed weight in fresh fructification weight ,length and width of the seed, seeds weight, germination potential, germination rate, seedlings height of Prinsepia utilis of different geographica provenance, the result showed that the above indexes was complicated and variational. Even in same geographica provenance,the different family＇ s indexes were also different. The relation between provenance temperature and the indexes of proportion of seed weight in fresh fructification weight, seed weight, width of seeds were dose.
