枫杨(Pterocarya stenoptera DC.)是我国平原湖区主要造林绿化树种。但枫杨丛枝病危害较严重。该病在山东、江苏、浙江、河南及安徽等省点片发生。据《中国森林病害》(1984)报道,在南京1954年首次发现此病,并认为该病的病原为核桃微座孢菌(Microstroma juglandis)。自1967年发现类菌原体(MLO)微生物是导致植物丛枝病的病原以来,各国竞相研究,已报道百余种植物受MLO危害,但一些具有黄化、丛枝症状的树木病害被陆续证实是
Pterocarya stenoptera DC. Is the main afforestation tree species in the plain lake area of China. But Maple pine broom disease more serious. The disease occurred in Shandong, Jiangsu, Zhejiang, Henan and Anhui provinces. According to “China Forest Disease” (1984) reported that the disease was first discovered in Nanjing in 1954 and that the pathogen of the disease is Microstroma juglandis. Since the discovery of MLO microorganisms as a causative agent of plant birch disease in 1967, various countries have been competing for studies. More than a hundred species of plants have been reported to be at risk of MLO. However, some tree diseases with yellowing and bushy symptoms have been successively reported Confirmed yes
