Abstract

During the years 2013–2015, the occurrence of fungi causing postharvest diseases of apples was evaluated in three apple orchards with integrated and organic production systems in the Czech Republic. The postharvest disease fungi were more frequently recorded in fruits from organically cultivated apple trees (average 29.97%) than those from integrated production (17.67%). This difference is statistically significant. Neofabraea, Penicillium, Alternaria and a sterile grey mycelium were the most frequently recorded taxa in apples grown in organic and integrated production systems. There were also significant differences in the frequency of occurrence of the most frequent fungal taxa between years. In 2013 and 2014, Neofabraea was the most frequently isolated genus in both cultivation systems, whereas in 2015, Penicillium was the most frequently recorded genus also in both cultivation systems, which was likely caused by the low precipitation in the 2015 growing season.
捷克共和国果园有机和综合生产系统中种植的苹果采后病害真菌发生情况的比较。
在2013-2015年期间,对捷克共和国三个采用一体化和有机生产系统的苹果园中引起苹果采后病害的真菌的发生情况进行了评估。有机栽培苹果树采后病害真菌的发生率(平均29.97%)高于综合生产苹果树(17.67%),差异具有统计学意义。Neofabraea、Penicillium、Alternaria和无菌灰色菌丝体是有机和综合生产系统中种植的苹果中最常见的分类群。最常见真菌类群的发生频率在年份之间也存在显著差异。在2013年和2014年,Neofabraea是两个栽培系统中最常分离的属,而在2015年,Penicillium是两个种植系统中记录最频繁的属,这可能是由2015年生长季节的低降水引起的。
