为探讨马缨杜鹃种子适宜的短期贮藏技术，对采自4个居群的马缨杜鹃种子进行不同温度下贮藏30 d和310 d的发芽试验。结果表明，贮藏30 d时，常温、冷藏（4℃）和冷冻（-20℃）条件下的种子发芽率差异不显著，但发芽势差异显著，常温贮藏下发芽势最高；不同居群种子发芽率差异显著，发芽势差异不显著，其中马雄山居群种子的发芽率和发芽势最高，常温贮藏方法较适合于对马缨杜鹃种子30 d左右的短期贮藏。贮藏310 d时，常温、冷藏和冷冻条件下的种子发芽率和发芽势差异均显著，冷藏条件下发芽率和发芽势最高；不同居群种子发芽率和发芽势差异均不显著。随着贮藏时间的延长，发芽率均表现为下降的趋势，而冷藏条件下贮藏310 d的种子发芽势显著高于贮藏30 d。因此，冷藏是马缨杜鹃种子310 d左右短期贮藏的适宜方法。

In order to investigate the suitable method for short-term storage of Rhododendron delavayi seeds, the germination tests of seeds,collected from 4 populations of R.delavayi and stored under different temperatures for 30 d and 310 d were conducted.The results showed that,after 30 d of storage under room temperature,4℃and-20℃,the differences of seeds germination rate were not significant,but significant differences appeared in ger-mination potential,and the seeds germination potential was highest when they were stored at room temperature. Simultaneously,the differences of seeds germination rate between collection populations were statistically signifi-cant,but was not significant in seeds germination potential.Among four populations,Maxiongshan population seeds held the highest germination rate and germination potential.Therefore,room temperature storage was more suitable for R.delavayi seeds to store about 30 d.After 310 d of storage at room temperature,4℃and -20℃,the differ-ences of seed germination rate and germination potential all were significant,and seeds stored at 4℃had the high-est germination rate and germination potential.However,the differences of seed germination rate and germination potential between collection populations were not significant.Furthermore,with the extension of storage time,the seed germination rate showed a decrease trend,but germination potential of seeds stored at 4℃for 310 d were sig-nificant higher than that of the seeds stored at 4℃for 30 d.Thus,it was concluded that 4℃was the suitable storage for R.delavayi seeds to store about 310 d.
