摘要: 通过原产地调查,引种试验,扦插及种子萌发等实验,研究了太行花的繁殖及扩散方式。结果表明,太行花有两条生殖途径:一条是有性生殖;另一条是无性生殖。在原产地因生境条件特殊,有性生殖能力弱,主要靠无性生殖扩大种群。在北京人工栽培条件下,两种生殖方式都能正常进行。

AbstractThrough investigations of original growing area,tests of introduction variety,cutting tests and seed germination,the reproduction of T.rupestris and expanding patterns of the species group were studied.Results showed that there were two ways of reproduction in T.rupestris.One way was sexual reproduction.The other way was asexual reproduction.Due to bad habit condition in the original growing area the sexual reproductive abilityof T.rupestris became very weak and expanding of the species group mainly depended upon the asexual reproduction.Under artificial cultivation in BeiJing both ways of the sexual and asexual reproductions of T.rupestris were normal.
