对樟子松枯梢病菌生物学特性的研究结果表明 ,该菌在PDA培养基上生长最佳 ;最适温度 2 5℃ ;最佳pH =5 ;最佳C源为蔗糖 ;最佳N源为蛋白胨 ;全光最适其生长 ,并能产生分生孢子器和分生孢子。病原菌分生孢子在 2 5～ 32℃下、2 %葡萄糖中、10 0 %相对湿度下 ,孢子萌发率最高。但随湿度降低 ,萌发率逐渐下降。
The study on the biological characteristics of Pinus sylvestris var. Mongolica showed that the strain grew best on PDA medium; the optimum temperature was 25 ℃; the optimum pH was 5; the best C source was sucrose; the best N source Peptone; all light best for its growth, and can produce conidia and conidia. The spore germination rate of the pathogen conidia at 2 5 ~ 32 ℃, 2% glucose, 10 0% relative humidity was the highest. However, with the decrease of humidity, germination rate decreased gradually.
