光照、pH及NAA浓度对野生淡黄花百合种子萌发的影响

Infuence of Light,pH and NAA on the Germination of Lilium sulphureum Baker

通过对野生淡黄花百合的种子进行遮光、不同pH溶液和不同浓度NAA处理后观察种子萌发的各项指标,探讨其种子萌发的最佳条件。结果表明:自然光照有利于种子的萌发;淡黄花百合在pH为6酸性条件下萌发率、整齐度、苗长、健壮程度等都优于碱性环境;用1.0g/LNAA处理可以提高淡黄花百合的萌发率、缩短淡黄花百合萌发所需的时间。

The effects of light,pH and NAA on the germination of Lilium sulphureum were researched.The results showed that the seed germination of Lilium sulphureum was significantly promoted by light,the appropriate range of pH for seed germination was 4 to 8 and 6 was the optimum for seed germination and seedling growth.The germination rate in 1,0 g/L of NAA was 96%higher than the other concentratioa At the consition of nature light and pH 6,the germination rate was the highest,germination time was the shortest,healthy and strong of seedling was the best.The seed germination of Lilium sulphureum was significantly promoted by NAA,but the germination,time was longer.
