| 摘 要： | 通过原产地调查、栽培试验、分根扦插及种子萌发实验等，研究了高山红景天的繁殖及扩散方式。结果表明：高山红景天有两条生殖途径，一条是有性生殖，另一条是无性生殖。在原产地生境条件恶劣的情况下，有性生殖能力弱，主要靠无性生殖来产生大量后代，保存物种；而在太平沟人工移栽条件下，两种生殖方式都能正常进行。

| Abstract: | Through investigations of original growing area, tests of introduction variety, cutting tests and seed germination, the reproduction of Rhodiola sachalinensis and expanding patterns of the species group were studied. Results show that there are two ways of reproduction for Rhodiola sachalinensis . One way is sexual reproduction; the other way is asexual reproduction. Due to the bad habitat condition in the original growing area the sexual reproductive ability of Rhodiola sachalinensis became very weak, and the expanding of the species group mainly depended upon the asexual reproduction. Under the condition of artificial cultivation in Taipinggou both ways of the sexual and asexual reproductions of Rhodiola sachalinensis were normal. |
