摘　　要：0引言百香果(Passiflora edulis),学名西番莲,为西番莲科(Passifloraceae)西番莲属(Passiflora Linn.)草质藤本植物,原产于南美洲的巴西,在我国主要种植于热带、亚热带地区,具有极高的营养、保健和商品价值[1-2]。目前,我国百香果的主栽品种为紫果百香果(Passiflora edulis Sims var.edulis).In September 2019,an unknown rot disease was found on passion fruit of the yellow type that was marketed in Yulin,Guangxi province.The pathogens were isolated by tissue separation method from tissues of diseased passion fruits,and their pathogenicity were verified through Koch′s postulates.According to the morphological characteristics and combined with rDNA-ITS and TEF1-αgene sequences,the pathogen was identified as Lasiodiplodia theobromae.To our knowledge,this is the first repot of postharvest fruit rot in passion fruit caused by L.theobromae.
