摘　　要：在叶枯病的发病高峰期,对成蒜早2号和温江红七星的叶枯病发展变化进行追踪调查。调查结果表明,成蒜早2号表现出苗快、叶片生长迅速;二者叶枯病发病时间相同,为害程度相当,但成蒜早2号前期发病较轻,中间还有起伏,表现出抗病性。The development changes of the leaf blight on Chengsuanzao No.2 and Wenjianghongqixing were surveyed in the high incidence period of the disease.The results showed that the two cultivars had the same onset time and the similar harmed degree of the leaf blight.And the Chengsuanzao No.2 showed better resistance to the leaf blight at the initial stages,and the disease development was slower and fluctuant,which possessed early emergence of seedlings and the rapid growth of leaves.
