不同氮源对棉花炭疽病病原菌的影响研究

摘要

研究不同氮源对棉花炭疽病病原菌的影响，结果表明：以硝酸钠为氮源培养基时产孢量最高，以蛋白胨为氮源培养基时病原菌生长速率最大。%Effect on cotton anthracnose pathogen of nitrogen was studied.The results showed that sporulation was the highest using sodium nitrate as nitrogen and pathogen growth rate was the maximum using peptone as nitrogen.
