桃枝枯病新病原三线镰刀菌的鉴定及药食两用中草药对其抑制作用
Identification of Fusarium tricinctum as a novel pathogen causing peach shoot blight and inhibitory effects of edible and medicinal Chinese herbs on the pathogen
摘要
Abstract
Peach shoot blight is an important fungal disease affecting peach cultivation,which can cause shoot wilting and necrosis.Diaporthe amygdali has long been recognized as its main pathogen;however,D.arecae and D.eres have also been identified as causal agents of this disease in Huishan and Wujin regions of Jiangsu province.In this study,morphological characteristics combined with multigene identification were used to identify Fusarium tricinctum as the pathogen of peach shoot blight prevalent in Nantong,Jiangsu province,in recent years for the first time.This pathogen was also found to cause postharvest rot of peach fruits.In vitro antagonistic assays showed that edible and medicinal Chinese herbs(e.g.,cinnamon,clove,and garlic)exhibited strong inhibitory effects on the growth of F.tricinctum.At a concentration of 20 μL/mL,their main active components(cinnamaldehyde,eugenol,and allicin)showed inhibition rates of 56.27％,25.10％,and 3.92％,respectively;meanwhile,these compounds also reduced the rot-inducing effect of F.tricinctum on peach fruits.These results provide a scientific basis for the development of green control technologies for peach shoot blight.关键词
