竹丛枝病病原研究进展

 竹丛枝病是竹类植物产生丛枝状病害的总称，是竹林退化最具破坏性的病害之一。大量研究表明：竹针孢座囊菌Aciculosporium take，异香柱菌属Heteroepichloё，竹暗球腔菌Phaeosphaeria bambusae以及植原体（phytoplasma）等均能引起竹丛枝病。长期以来这些病原物所处分类地位的变化较大且它们的致病机制尚不清楚，这对竹丛枝病的防治造成了极大的困难。对上述病原物所处分类地位的演变过程及其致病机制的研究进行了综述，并对竹丛枝病今后的研究方向进行了展望。参26

Research progress on pathogens of witches’ broom of bamboo

The witches’ broom of bamboo is one of the most destructive causes of the deterioration of bamboo forests. A large number of studies have shown that Aciculosporium take，Heteroepichloё，Phaeosphaeria bambusae and phytoplasma are pathogens of witches’ broom of bamboo. However，since the taxonomic status of these pathogens have been changing for a long time and their pathogenesis are unclear，it’s too difficult to control this disease efficiently in bamboo forests. The evolution of the taxonomic status of these pathogens and studies on their pathogenesis were reviewed and the prospects of the future study on witches’ broom of bamboo were discussed.［Ch，26 ref.］
