广东省裁培药用植物上弯孢类型炭疽菌的鉴定

 作者按照Sutton的分类系统,把标准培养特性、致病力和寄主范围等作为分种的主要特征,对广东省15种栽培药用植物上的弯孢型炭疽菌进行研究,共鉴定出3个种,即辣椒刺盘孢(Colletoptrichum capsici)、百合刺盘孢(C.liliacearum)和束状刺盘孢(C.dematium]报道了辣椒刺盘孢的7种新寄主,即:良姜(Alpinia officinarum Hance)何首乌(Polygo-hum multiflorum Thunb.)五叶参Pentapanax leschenaultii (Wight&Arn.) Seem].龙利叶(Sauropus spatulifolius Beille)、穿心莲Andrographis paniculata (Burmf).Nee.]佛手(Citrus medica L.)、山柰(Kaempferia galanga L.)辣椒刺盘孢在广东分布普遍,致使淮山、何首乌和佛手等遭受重大损失。

IDENTIFICATION OF FALCATE-SPORES OF COLLETOTRICHUM ON MEDICAL PLANTS CULTURED IN GUANGDONG PROVINCE

Based on Sutton's Monograph, the principle for species identification was accepted that standard culture characters, pathogenicity and host range were the main characters. Falcate-spores of Colletotrichum of 15 medical plants cultured in Guangdong Province had been studied during 1989~1990, and 3 species were recognized. They were C. capsici. C. liliacearum and C. dematium;7 new hosts of C. capsici were reported, they were Alpinia officinarum Hance, Polygonum multiflorum Thunb., Pentapanax leschenaultii (Wight et Arn.)Seem., Sauropus spatulifolius Beille, Andrographis paniculata (Burmf.)Nee., Citrus medica L., and Kaempferia calanga L., C. capsici distributed widelg in Guangdong Province, and caused serious damage on Dioscorea opposita, Poly-gonum multiflorum, Citrus medica and etc.
