为提高红景天种子的发芽率，扩大繁殖，进行了种子处理试验，联合方差分析结果表明；流水处理与激素处理是提高发芽率的有效途径，且２００ｐｐｍ和５００ｐｐｍ的ＧＡ３作用显著。生活力测试表明：红景天种子的生活力随贮存时间的推移迅速降低。当年苗床观察结果表明：红景天一年生苗的生育期约为１００天，前期有近４个星期的“株交滞育”阶段。
In order to improve the germination rate of Rhodiola rosea seed, the experiment of seed treatment was carried out. The result of joint analysis of variance showed that water treatment and hormone treatment were effective ways to improve the germination rate, and the effects of 200ppm and 500ppm GA3 were significant. Vitality test showed that the viability of Rhodiola rose rapidly with the storage time. The observation of the seedbed in the year showed that the annual growth period of Rhodiola rosea was about 100 days and that of the early stage was nearly 4 weeks.
