摘要
Abstract
The resistance of different apple cultivars in the Beijing area to early deciduous disease of apples was explored,providing a reference for the classification of apple variety resistance,and at the same time,the pathogenic fungal species were identified.A field survey was conducted on the incidence of early deciduous disease of apples in 21 apple cultivars with a certain cultivation scale in the Beijing area,and the disease index was statistically analyzed.According to the disease index classification:'Ambrosia'has the highest resistance to apple blotch leaf fall disease,and'Shinano Gold'has the lowest;'Ruixue'and'Ruixianghong'have the highest resistance to apple anthracnose leaf blight,and'Hirakaga Tsugaru'has the lowest resistance.According to Koch's postulates,biological observations were made on diseased leaves,and the isolated fungi were purified and cultured.Through sequencing and comparison,inoculation and re-isolation verification,the pathogenic fungal species were determined:Alternariaand Colletotrichumwere the pathogenic fungi of early deciduous disease of apples.关键词
