广东鸡蛋果真菌病害调查初报

A PRELIMINARY REPORT OF THE PASSIFLOWER DISEASES IN GUANGDONG

1989～1990年,对广州、惠州二市的鸡蛋果(Passiflora (?)is Sims)病害进行了调查,共鉴定10种病原真菌,包括2个新种:Phomopsis passiflorae J.F.Lu et P.K.Chi,引起果腐,及My-cosp(?)hella Passiflorae J.F.Lu et P.K.Chi,引起叶斑;1个新组合:sphoeropsis Passifloricola(Grove)J.F.Lu et P.K.Chi亦引起叶斑;2个国内新纪录:A(?)(?)(?)及Phommopsisterso(Sacc.)Sutton.但生产上为害最严重的是:Nectria haematocooca Berk.et Br.引起的茎基腐病及Ph(?) (?) VAr.p(?) (Dast.)Watern.引起的疫病,它们与病毒引起的花叶病是鸡蛋果生产中的三大病害。 新种及新组合的标本存华南农业大学植保系标本室。

10 fungal pathogens on passiflower (Passiflora edulis Sims) in Guangzhou and Huizhou were identified during 1989~1990.Among them,Basal rot (Nectria haematococca Berk,et Br.) and Phytophthora blight (Phytophthora nicatianae var.parasetica (Dast.) Waterh.) are the three major diseaseson passiflower with the viruses caused by CMV.Other fungal pathogens are fruit rot (Phomopsis passiflorae J.F.Lu et P.K.Chi n.sp.),Leaf spot (My-cosphaerella passiflorae J.F.Lu et P.K.Chi n.sp.,Sphaeropsis passiloricola(Grove)J.F.Lu et P.K.Chi n.comb,and Phoma sp.),Alternaria leaf spot and fruit rot (Alternaria passiflorae Simmons).Phomopsis leaf blight (Phomopsis tersa (Sacc.) Sutton) ,Anthracnose (Colletotcichum capsici (Syd.) Butler & Bisby,C.gloeosporioides Peru.),and Brown leaf spot (Phoma sp.).Two mew species were described in Latin and Chinese.Their type specimens are deposited in the Department of Plant Protection,Sorth China Agricultural University,Guangzhou,China.
