【摘要】 分布在东北4个地区的毛百合在形态性状、繁殖特性上均存在显著差异.在温暖湿润的长白山、张广才岭等地区的生长较快,花果较大,种子千粒重较重,观赏性状表现良好;在气候寒冷干燥的大、小兴安等地的性状表现均较差,形态性状指标基本随纬度减小而增加,随经度的增加而加大.不同种源间大兴安岭的种子发芽率最高,发芽率有随纬度降低而降低的趋势.过氧化物同功酶测定表明:不同种源间有两条相同的基本酶带,其它酶带种源间存在差异.更多还原

【Abstract】 The morphological characters and breeding habits of L. dauricum distributed in 4 different regions in Northeast China are obviously different. The type at Changbai Mountain and Zhangguaricai Mountain , where the climate is warmer and moister exhibited faster growth , larger flowers and fruits, heavier seeds and better ornamental cuaracteristics; while these characters of the same type are worse in Xiaoxing’an Mountain and Daxing’an Mountain , where climate is colder anc drier . Those character indices declined with latitude increasing and increased with longitude increasing. The germination rate from Daxing an Mountain among different provenances was the fastest . The index tend to slow step by step with the latitude from north to south. The examination of perxidose showed that there were two common basic perxidose speetrums among different provenances and the other perxidose spectrum were much different.更多还原
