| 摘 要： | 通过反复选择试验,从40个马尾松种源中选出既抗松材线虫病又较抗松褐天牛补充营养取食的广东5号种源.接种松材线虫使抗病马尾松种源中某些萜类组分如长叶烯、酚性化合物等增多;而抗松褐天牛取食种源含有更多的单萜烯、倍半萜烯、石竹烯等,含有更少长叶烯,这可能与松材线虫和松褐天牛的取食习性不同有关.游离氨基酸含量低的马尾松种源能抗松褐天牛成虫补充营养取食和抗松材线虫病.这与游离氨基酸含量低的马尾松种源抗性强的观点一致.厚皮紧密型的树皮结构和旺盛的树木生长势也是抗性种源抗性强的原因.

| Abstract: | A masson pine (Pinus massoniana) provenance,Guangdong 5,that was selected from 40 provenances by repeated selections,had resistance to both pine wilt disease (PWD) and maturation feeding by the adults of Monochamus alternatus.When inoculated pine wood nematode,resistant masson pine provenances produced more terpene components,such as longifolene,and phenolic compounds.Provenances with resistance to maturation feeding by the adults of M.alternatus contained more contents of monoterpene,sesquiterpene,caryophy... |
