摘　　要：以新疆野杏为研究对象,采用野外调查和室内测定方法,对整个生殖季节新疆野杏各器官生物量和氮磷钾的生殖配置变化进行研究。结果表明,新疆野杏生殖器官生物量在花期逐渐增加,花谢时逐渐减小,果实成熟期再次迅速增加至最大,整个生殖季节生物量平均生殖配置为43.42%。开花期间生殖器官氮磷钾含量高于营养器官,尤其是钾含量明显高;幼果初期生殖器官氮磷钾含量低于营养器官,随着果实长大成熟,生殖器官氮磷钾含量表现出升高趋势。在时空资源有限的条件下,新疆野杏较高的生殖配置有利于种群自身生存发展。T he biomass and N ,P ,K reproductive dynamic allocation for the w hole breeding season of Armeniaca vulgaris Lam .were researched by adopting field investigation and indoor determination .The results showed that reproductive organ biomass increased gradu‐ally during flowering ,decreased gradually during flower fade ,and increased rapidly during fruit ripe .The average reproductive allocation was 43 .42% in the whole breeding season , with higher N ,P ,K content of reproductive organs than that of the vegetative organs during flowering ,especially with significantly higher K content .The N ,P ,K content of reproduc‐tive organs was inferior than that of the vegetative organs during ovary expands .As the fruit mature ,the N ,P ,K content of reproductive organs showed a rising trend .The higher repro‐ductive allocation could contribute to the population survival and development of A rmeniaca v ulgaris Lam .under limited time and space resources .
