摘　　要：研究结果表明：麦冬炭疽病病原为黑线炭疽菌［Ｃｏｌｌｅｔｏｔｒｉｃｈｕｍｄｅｍａｔｉｕｍ（Ｐｅｒｓ．ｅｘＦｒ．）Ｇｒｏｖｅ］．该菌的分生孢子萌发最适温度为２５℃，致死温度为６０℃；在相对湿度１００％条件下萌发率最高；分生孢子萌发的最适ｐＨ值为５．３～８．０；营养液以马铃薯蔗糖液和查彼培养液为好；单糖、双糖和多糖作为碳源都能很好地被病菌利用，以甘露糖为碳源的培养基生长最好；黑光灯照射对分生孢子萌发有一定抑制作用。It is shown by the 1991～1994 study that the anthracnose fungus of Ophiopogonjaponicus is Colletotrichum dematium(Pers. ex Fr.)Grove. The optimun temperature,relative humidity and pH value range for conidia germination is 25℃,100%and pH 5.3～8.0 ,respectively. The TDP is 60℃×10min。The fungus grows better on potato-sucrosemedium and Czaper’s medium ,and it can use monosaccharide,bisaccharides andpolysaccharides as the sole carbon source. The fungus grows best on the medium whichmannose is the sole carbon source. UV radiation can inhibit the germination of conidiapartly.
