报道毛竹基腐病(Arthriniumphaeospermum)侵染循环的研究结果:(1)病原菌以菌丝或孢子的形态在病竹、枯立竹和病株残体及土壤内潜伏越冬成为次年初次侵染的来源;(2)风、随风的雨和雨水反溅是孢子传播的主要途径;(3)在自然情况下,病菌主要通过幼嫩的无伤在皮侵入寄主体内;(4)通过田间观察和病变组织的分离培养试验结果,结合病原菌本身的特性可以初步确定该病菌是通过分泌毒素杀死寄主细胞后进入寄主组织的;(5)该病没有再次侵染。
The results of research on the infection cycle of Arthriniumphaeospermum were reported: (1) The pathogen was latent infection in diseased bamboo, withered bamboo, diseased plant residue and soil in the form of mycelium or spore Source; (2) wind, windy rain and rain splashes are the main route of spore propagation; (3) in natural conditions, the germs mainly invade into the host through the tender and innocuous skin; (4) And diseased tissue culture test results, combined with the characteristics of the pathogen itself can be initially identified by the pathogenic bacteria to kill the host cell secretion of toxin into the host tissue; (5) the disease did not re-infection.
