摘　　要：对板栗拟茎点霉菌Phomopsis castaneae-mollissimae协同致病菌Ophiognomonia castanea的生物学特性进行了研究。结果表明,O.castanea菌丝在马铃薯-板栗叶培养基上生长最好,菌丝生长的适宜温度为15-28℃,最适温度为25℃,最适p H为6;最适宜碳源为甘露醇,氮源蛋白胨和牛肉浸膏能促进菌丝生长。The biological characteristics of Ophiognomonia castanea,a synergistic pathopoiesis fungus of Phomopsis castaneae- mollissimae,were studied in this paper. The results showed that： O. castanea mycelia grew best in potato- chestnut leaf culture medium. The suitable temperature for mycelia growth was 15 -28℃,and the optimum temperature was 25℃. The optimum p H value was 6. The optimum carbon source was mannitol. The peptone and beef extract as nitrogen sources could promote the mycelia growth.
