| 摘 要： | 本研究测定了不同培养基、碳源、氮源、温度、pH条件下臭椿盘长孢刺盘孢(Colletotrichum gloeosporioides Penz.)菌株SQD-107的生长、产孢和孢子萌发情况.该菌株在PSA培养基上生长最快、产孢最多;在供测碳源中病原菌对蔗糖、葡萄糖利用较好,供测氮源中对硝酸铵、氯化铵利用较好.菌丝生长的适宜温度范围为10-35℃,最适25℃;产生分生孢子的适宜温度范围为10～30℃,最适25～30℃;孢子萌发的适宜温度范围为5～35℃,最适25℃.在pH3～10的范围内该菌均能生长和产孢,菌丝生长最适pH7～8;产生分生孢子最适pH为7.孢子萌发最适pH 6～8.孢子的致死温度为60℃,持续时间10 min. |

| Abstract: | In our previous study,the SQD-107 was isolated from anthracnosed leaves of tree-of-heaven (Ailanthus altissima)in China and was morphologically identified as Colletotrichum gloeosporioides Penz.In the present study,the effect of media,carbon sources,nitrogen sources,temperatures and pH values on mycelialgrowth, sporulation and conidial germination of SQD-107 was tested and analyzed.The results indicated that potato sucrose agar(PSA)was found the best medium for mycelial growth and sporulation of the fungus.... |
