人参黑斑病原菌生长发育温度幅度是5～30℃注适温度为25℃.pH值范围在pH为4～12之间培养基础上生长良好,但以pH6为最佳.各光照处理对菌落的形成影响差异不显著,在紫外灯连续照射下孢子形成量最多,经紫外灯,日光灯处理都可促进分生孢形成.该菌在PDA、参根煎叶、大米培养基上生长速度快,参根培养基有促进病菌生殖生长的效能。病原菌能有效地利用各种碳源,以淀粉为最佳,麦芽糖次之.氮源以谷氨碳最好,其次是硝酸钠.微量元素以锰、钼对菌丝生长有利,铜、锌不利于菌丝发育.
The growth and development temperature range of ginseng black spot pathogens is 5 ~ 30 ℃, the suitable temperature is 25 ℃ .The range of pH value is good at pH 4 ~ 12, but pH 6 is the best.At the same time, The difference of formation was not significant, the spore formation was highest under the continuous irradiation of UV lamp, and the spore formation could be promoted by ultraviolet lamp and fluorescent lamp.These bacteria could grow on PDA, ginseng leaf and rice medium fast, Root medium to promote germ growth and reproductive efficiency. Pathogenic bacteria can effectively use a variety of carbon sources, starch is the best, followed by maltose.Nitrogen source to the best of the carbon and ammonia, followed by sodium nitrate.Microelements of manganese, molybdenum on mycelium growth, copper, zinc is not Conducive to mycelial development.
