10种百合属植物的传粉生物学
摘要： 对百合属(Lilium)10种植物的自花传粉和种间传粉进行了初步观察分析,结果为:轮叶百合、有斑渥丹、王百合及毛百合自花不孕。川百合和条叶百合同株异花授粉的亲和性好于同花授粉的亲和性。在常规授粉条件下,种间授粉亲和性与形态学亲缘关系不完全一致。在13组杂交组合中,同是卷瓣组的细叶百合和垂花百合,正反交分别得到16%和25%的有胚种子;同为钟花组的毛百合和有斑渥丹,正反交均不座果;卷瓣组的条叶百合×百合组的王百合得到12%的有胚种子,种子发芽率64%;轮叶百合(轮叶组)×王百合得到82%的有胚种子,种子发芽率85%。

Abstract: Self-pollination and interspecific-pollination were studied in 10 species of Lilium.The result shows that in L.d istichum, L.concolor var.pulchellum, L.dauricum and L.regale self-pollination is sterility.Affinity of cross-pollination in one plant is better than self-pollination in L.davidii and L.callosum.Affinity in interspecific-pollination is different sith norphology with convention.Thirteen crossing groups were researched.In same group, after reciprocal crosses of L.pumilum and L.cernum, we can get 16% and 25% albuminous seed, L.callosum×L.regale, we can get 12% albuminous seed, that it germination rate is 64%.In another group, reciprocal crosses of L.dauricum and L.concolor var.pulchellum, had not seed.In L.distichum×L.regale, we can get 82% albuminous seed, that it germination rate is 85%.
