研究结果表明:山茱萸炭疽病菌分生孢子萌发的最适温度为23—28℃,致死温度在50—55℃之间,在相对湿度100%条件下萌发率最高,分生孢子萌发的最适pH值为5—6.需要的营养以1%蛋白胨液和查彼氏培养液为好,单糖、双糖和多糖作为炭源都能很好地被病菌利用,以在甘露糖为碳源的培养基上生长最好.荧光灯和黑光灯照射对孢子萌发有影响,紫外光对分生孢子有强烈的杀伤作用.分生孢子离体寿命为3—4天.用纸碟抑菌圈法对15种农药进行了毒力测定,以50%退菌特可湿性粉剂和40%拌种双可湿性粉剂抑菌效果最好,多菌灵次之,代森锌的抑菌效果较差.
The results showed that the optimum temperature for the conidia germination of the species was between 23 and 28 ℃, the lethal temperature between 50 and 55 ℃, the highest germination rate under the relative humidity of 100% and the optimum pH for conidia germination The value of 5-6. The required nutrition to 1% peptone solution and check the bacteria culture solution is better, monosaccharides, disaccharides and polysaccharides as a carbon source can be a good use of bacteria to mannose in carbon culture The best growth on the base.Fluorescent light and black light irradiation on the spore germination, UV light on the conidia have a strong killing effect.Conidia in vitro life of 3-4 days. The pesticides were tested for their virulence. Bacteriostatic effect of 50% dewetted WP and 40% doubly WP was the best, followed by carbendazim, and the detoxification of dexmedezine was poor.
