树栖真菌群落多样性研究Ⅰ.──红松芽、叶及短枝栖真菌群落组成分析

STUDIES ON DENDROCOLA MYCOSYNUSIAL DIVERSITIES Ⅰ.──FUNGAL COMMUNITIES' COMPOSITION OF BUDS, NEEDLES AND SHORT TWIGLETS ON PINUS KORAIENSIS

文章提出了树栖真菌的概念,并且以红松为例,对芽栖真菌、叶栖真菌和短枝栖真菌在不同树龄与叶龄以及不同树冠层次的情况下,进行了树栖真菌的群落组成和数量分析。共分离获得芽、叶、短技栖真菌59种。

The concept of dendrocola fungi is discussed in this paper.Mycosynusial composihon on buds, needles and short twiglets of Pinus koraiensis was inveshgated. Fifty-nine taxa were idenhfied from these microhabitats. Quantitative analyses were catried out of different mycosynusia. Fungal composihon between the body and the scale of buds was obviously difference. Generaly, the composition of species and quantity in each mycosynusiae increased with ages of needles and with tree crown storey decreasing. And the isolahon quantity of a latent infechous pathogen of needles, hahodermiu maximum, increased rapidly with tree crown storey decreasing even there was no any symptom observed.
