【摘要】 本试验对板栗褐缘叶枯病病原菌——板栗拟茎点霉菌生物学特性进行了研究。结果表明:病原菌菌丝在PSA培养基上生长最快;病原菌最易利用的碳源是葡萄糖,最易利用的氮源是氯化铵和甘氨酸;菌丝生长的最适温度为25℃,最适pH值为5~6。病原菌分生孢子在清水及多种营养液中均可以直接萌发,孢子萌发最适温度为20~30℃,最适相对湿度为85%,最适pH值为5。更多还原

【Abstract】 The Phomopsis mollissima pathogen ——Phomopsis(Sacc.) Bubak was purified from Castanea mollissima and its biological characteristics were studied.The results showed that the mycelia grew the fastest on the medium PSA;the optimal carbon source was glucose;the optimal nitrogen source were NH4Cl and glycine;the optimal temperature was 25℃ and the optimal pH value was 5~6.The conidia could germinate in water and many kinds of nutrient solutions under the optimal conditions of temperature as 20~30℃,pH value as 5~6 and the relative humidity as 85%.更多还原
