摘　　要：菠萝蜜(Artocarpus heteophyllus Lam),又称木菠萝,是桑科(Moraceae)木菠萝属(Artocarpus)的常绿热带果树[1]。近年来我国菠萝蜜产业发展迅速,种植面积约达1万公顷,其中约50%位于海南[1]。国内外已报道的菠萝蜜病害种类很多,包括花果软腐病[2-6]、蒂腐病[5-6]、果胞锈病[7]、根腐病[8-9]和根结线虫病[10]等。其中在果柄病害方面,LIU等[5]和LUO等[6]分别报道了可可球二孢菌(Botryodiplodia theobromae)和胶孢炭疽(Colletotrichum gloeosporioides)引起的菠萝蜜蒂腐病。Jackfruit(Artocarpus heteophyllus)is an important tropical fruit in Hainan.In July 2019 and June 2021,a new fruit stalk wilt on jackfruit with an average incidence of about 16%was observed in plantations in Ledong(18°52′11″N,108°41′57″E)and Wanning(18°69′43″N,110°17′19″E).Five fungus isolates were obtained from diseased samples of two different locations,were identified as Fusarium solani based on morphological characteristics.Isolates of this study and F.solani strains available in GenBank were clustered as a distinct clade with 98%and 100%bootstrap support in phylogenetic analysis,based on sequence similarity of ITS and LSU,respectively.Upon inoculation,the isolated F.solani caused fruit stalk wilt on healthy jackfruit,and F.solani isolates were consistently reisolated from the diseased fruit stalk,thus fulfilling Koch’s postulates.To our knowledge,this is the first report of fruit stalk wilt caused by F.solani on A.heteophyllus in China.
