对陇蜀杜鹃(Rhododendron przewalskii)种子做了不同处理的发芽试验,结果表明:陇蜀杜鹃种子发芽的适宜温度为10℃～15℃;用纯乙醚,95％乙醇溶液及一定浓度的硫酸、盐酸、硝酸、氢氧化钠等处理种子后,均能显著地提高种子发芽率;不覆土播种较覆土3mm的发芽率高;种子贮藏19个月后的发芽率较贮藏7个月后的发芽率高.
The results showed that the optimum temperature for germination of Rhododendron przewalskii seeds was 10 ℃ ~ 15 ℃. The germination tests of Rhododendron przewalskii seeds were carried out with pure ethyl ether, 95% ethanol and certain concentrations of sulfuric acid, hydrochloric acid , Nitric acid, sodium hydroxide and other seed treatment can significantly improve the seed germination rate; uncultivated soil covering 3mm higher than the germination rate; seed storage 19 months after the germination rate of storage than after 7 months of high germination rate .
