摘要
通过分离、接种、再分离首次证实杂交竹梢枯病的病原为暗孢节菱孢菌Arthrinium phaeosper-mum(Corda)M.B.Ellis。该病菌以菌丝体和子实体在病组织、病组织残体或土壤中越冬,其中病组织中菌丝体和子实体中的分生孢子为越冬的重要形式,是病害发生主要的初侵染源;病菌主要以分生孢子或菌丝通过伤口从节叉处侵入;病原菌主要通过孢子借助风力和雨水传播,从4月初开始释放孢子,6月为病原孢子释放的高峰期,并以分生孢子进行再侵染。
Arthrinium phaeospermum（Corda） M. B. Ellis was firstly referred as a pathogen of hybrid bamboo blight after isolation, inoculation, and re-isolation. It could overwinter in the diseased organization, or the soil as mycelium and conidium, The mycelium in diseased organization and conidium of fruiting body were the most important form during overwintering and the main primary infection origin. The pathogen invaded the node-fork through wounds by conidium or hypha and spread mainly by wind and rainwater. It released the spore in the beginning of April with a peak in June. and the secondary in-fection was caused by conidium.
