| 摘 要： | 试验证明,枸杞炭疽病(Colletotrichum gloeosporioides Penz)能较好地利用麦芽糖和蔗糖作为碳源。较适宜的氮源是KNO_3和蛋白胨。碳源中乳糖和甘油以及氮源中的尿素、(NH_4)_2SO_4和(NH_4)_2HPO_4对病菌苗丝生长和分生孢子的产生有明显抑制作用。病菌生长最适宜酸碱度为pH6.1。苗竺生长和孢子萌发适温为20～30℃,低于10℃和高于35℃孢子不能萌发。孢子萌发适宜湿度为100％,以水中萌发最好。湿度低于75.6％时孢子不能萌发。

| Abstract: | Colletolrichum gloeosporioides of matrimony vine can use maltose and saccharose as its carbon sources, and KNO3 and peptone as its nitrogen sources. However, lactose, glycerin, urea, (NH4)2SO4, and (NH4) 2HPO4 (can obviously inhibit the mycelia growth and conidia production-. It was shownd that pH 6.1 was most suitable for mycelial growth.The proper temperature for the mycelia growth and conidia germination was 20C to 30C. Ccnidia wculd not germinate either below 10C or above 35C.The relative humidity for conidia germination could not be lower than 75.6%. The optimal RH was 100%. |
