摘要: 四川人工桉树林中的巨桉、尾叶桉、兰桉、大叶桉有外生菌根、内生菌根和混合菌根3种菌根类型,而窿缘桉缺少混合菌根类型。自然状态下,5种桉树菌根化率有明显差异,其中以巨桉、兰桉最高,分别为68.3%、64.6%,而窿缘桉菌根化率最低(29.6%)。同一桉树树种,外生菌根化率最高,内生菌根化率次之,混合菌根化率最低。林分郁闭度对菌根真菌的分布有很大影响,随着森林郁闭度增加,桉树林分外生、内生菌根真菌的类群趋于复杂。

Abstract: There existed ectmycorrhiza, endomycorrhiza and dual mycorrhiza in Eucalyptus grandis, E. globules, E. urophyus and E. robusta while E. exserta is deficient in dual mycorrhiza in Sichuan. 5 species of Eucalyptus have significant differences in mycorrhiza infection under natural condition, of them, Eucalyptus grandis, E. globules, respectively 68.3%, 64.6%, have the highest mycorrhiza infection rates while E. exserta is the lowest in mycorrhiza infection rates(29.6%). For the same species of Eucalyptus, ectmycorrhiza, endomycorrhiza and dual mycorrhiza respectively rank first, second and third in mycorrhiza infection rates. It is concluded that forest density has the great influence on the distribution of mycorrhizal fungi, and ectmycorrhizal, endomycorrhizal fungi become complex as forest density increases.

Key words: ECTMYCORRHIZA, ENDOMYCORRHIZA, DUAL MYCORRHIZA, EUCALYPTUS GRANDIS, EUCALYPTUS GLOBULES
