| 摘 要： | 从江苏13个县市采集病叶标本,经分离、纯化后获280株菌。据鉴定结果和接种试验,稻生叶点霉(Phyllosticta oryzicola Hara)为主要致病菌,占74.6%。此外,还分离到稻盘多毛孢(Pestalotia oryzae Hara)、链格孢(Alternaria alternata(Fr.) Keissl.)、稻喙孢(Rhynchosporium oryzae Hash.et York.)、苍白弯孢(Curvularia pallescens Boed.)、新月弯孢(C.lunata(Walk.) Boed.)、膝曲弯孢(C.geniculata(Tracy et Earle) Boed.)、镰刀菌(Fusarium spp.)、平脐蠕孢(Bipolaris spp.)、稻黑孢(Nigrospora oryzae(Berk.et Br.) Perch)、球黑孢(N.sphaerica(Sacc.) Mason)等真菌。首次以透射电镜观察表明,稻生叶点霉产孢方式为全壁芽生单体式(hb-sol)。

| Abstract: | 280 isolates were obtained from the rice leaves infected by rice Phyllosticta leaf blight collected from 13 counties of Jiangsu Province, China. According to the results of identification and inoculation, Phyllosticta oryzicola Hara is the main pathogen causing leaf blight of rice. Otherwise,other fungi such as Pestalotia orysae Hara, Alternaria alternata (Fr. ) Keissl. , Rhynchosporium oryzae Hash, et York. , Curvularia pallescens Boed. , C. lunata (Walk. ) Boed. , C. geniculata (Tracy et Earle) Boed. , Fusarium spp. , Bipolaris spp. , Nigrospora oryzae (Berk, et Br. ) Fetch, N. sphaerica (Sacc. ) Mason, could accidently be obtained by the isolation of the diseased leaves. The conidiogenous cells of Phyllosticta oryzicola were observed to be holoblastic-solitary under the transmission electron microscope. |
