摘　　要：对大豆品种中黄55的复叶类型及不同种植地点各种复叶类型分布及其着生节位进行了研究,旨在探明多小叶的变化规律。根据组成复叶中小叶的数目,可分为7类,按照侧生和顶生叶片的数量进一步分为13种叶型,其中,4类共5种叶型尚未见报道。中黄55的复叶以三出复叶为主,其他复叶的小叶数以"4叶D1型"比率较高,随着纬度的降低,复叶类型数减少;北京顺义、湖北武汉和海南三亚3个地点间各小叶型比率方差分析表明,大部分小叶型比率3点间差异有统计学意义,表明复叶小叶型及其比率受环境的影响;主茎上从低节位至高节位,普通三出复叶的比率先是降低,然后再升高,而不同节位分枝的普通三出复叶的比率变化不大。通过本研究可拓宽对大豆复叶小叶型的认识。The object was to survey the variability of soybean leaflets by investigating the variant leaflets and their node position of emergence in Zhonghuang 55.The result indicate that there were seven leaf-type groups and 13 leaflet types,of which 5 leaflets as yet have not been reported.The main compound leaves were normal tripleleaflet type,following by the D1 type of 4 leaflets.Analysis of variance showed that significance differences exited among experimental sites for ratios of difference leaflet types,which indicated the leaf types and their ratios were affected by environments.The ratio of ternately compound leaves increased at first and then decrease from low node to high node in plants,while the ratio of ternately compound leave in branches had little change.The study will broaden our acknowledge to soybean leaf.
