摘要
[目的]明确长白山北坡森林土壤低温真菌的种类和分布特征。[方法]利用选择性培养基,研究长白山土壤低温真菌的数量分布和种群组成。[结果]长白山土壤低温真菌数量随生长月份的变化趋势是9月>7月>6月>8月,随着海拔高度的递减,低温真菌没有呈现出明显的分布模式;从土壤中共分离到低温真菌106株,分属于16属,其中以被孢霉属、毛霉属、青霉菌属和弯颈霉属为优势菌属。[结论]长白山低温真菌种群分布具有多样性。
[ Objective ] The research aimed to explore the population diversity and the distribution feature of low temperature fungi in Changbai Mountain. [ Method ] The quantity and structure of low temperature fungi groups were studied in Changbai Mountain by selective medium. [ Result] The variation trend of the numbers of fungi were September 〉 July 〉 June 〉 August. Low temperature fungi showed no obvious distribution pattern with the decrease of the elevation. 106 strains were isolated from soil fungi, which belonged to 16 genera. MortiereUa, Mucor, PeniciUium and Tolypocladium were dominate genera. [ Conclusion] Species structure of low temperature fungi exbibted diversities.
