摘　　要：在鉴定茶花(玛瑙)炭疽病病原菌的基础上,研究了碳源、氮源、光周期、pH值、温度及杀菌剂对茶花炭疽菌生长的影响。结果表明:该菌为Colletotrichum acutatumJ.H.Simmonds,其菌落生长的最佳碳源是可溶性淀粉,氮源是蛋白胨;光照有利于分生孢子萌发;分生孢子萌发的最适pH为5。温度在20～30℃时菌落生长最好,分生孢子萌发率最高;百菌清对该菌的抑制效果最好。Based on identification of Collelotrichumspp.on the Camelliacultivars Manao,the effects of carbon source,nitrogen source,photoperiod,pH value,temperture and fungicide on the pathogen’s growth and conidiospore germination were studied.The results showed that the pathogen was identified as Colletotrichum acutatum J.H.Simmonds;soluble starch was the most suitable carbon source and peptone was nitrogen source for colony growth,illumination and pH 5 was beneficial for conidiospore germination.20～30℃ was the preference temperature both for colony growth and conidiospore germination,the chlorothalonil had the greatest antifungal effect.
