研究了不同种子处理方法对樟子松幼苗生长的影响。结果表明,不同种子处理方法对樟子松幼苗生长影响明显,以10℃冷水浸种催芽处理效果最好;沙床催芽法效果次之;50℃温水浸种催芽法效果最差。建议在樟子松幼苗培育中采用冷水(10℃)浸种催芽方法和混沙埋藏催芽方法进行种子处理。
The effects of different seed treatments on seedling growth of Pinus sylvestris var. Mongolica were studied. The results showed that different seed treatments had significant effects on the seedling growth of Pinus sylvestris var. Mongolica, and the best seedling was treated with soaking seed at 10 ℃. The effect of germination by sand bed was second, and the soaking by warm water at 50 ℃ was the worst. It is suggested that seeds should be treated with cold water (10 ℃) soaking and germination method and mixed sand burial and germination method in seedling cultivation of Pinus sylvestris var. Mongolica.
