摘　　要：丽赤壳属真菌的一些物种是重要的植物病原菌,由丽赤壳属真菌引起的桉树叶焦枯病是桉树人工林重大病害之一。致病力试验表明在土壤中分离的一些丽赤壳属物种在测试的桉树上能引起典型的叶焦枯症状。本文对丽赤壳属真菌的物种多样性和分布进行了概述,对影响真菌在土壤中分布的环境因素和人为因素以及真菌在土壤中的垂直分布规律进行了综述,并总结了土壤中丽赤壳属真菌的诱导与分离方法,以期对进一步研究土壤中丽赤壳属真菌的物种多样性和致病性提供指导。Some species of the genus Calonectria are significant plant pathogens.Calonectria leaf blight caused by species of Calonectria is one of the most important diseases on Eucalyptus plantations.Pathogenicity tests showed that some species isolated from soil could cause typical leaf blight symptoms on the tested Eucalyptus trees.In this study,the species diversity and distribution of Calonectria species are summarized.The environmental and human factors affecting the distribution of these fungi in soil and their vertical distribution in soil are reviewed.Furthermore,the methods of induction and isolation of Calonectria from soil are documented.We expect to provide recommendations for further research on species diversity and pathogenicity of Calonectria spp.in soil.
