Status and Perspective on Research of Ear Rot and Stalk Rot in Maize
CHEN Jie. Status and Perspective on Research of Ear Rot and Stalk Rot in Maize[J]. Journal of Shenyang Aricultural University, 2000, 31(5): 393-401

Abstract:Major progresses about etiology, occurrence and pathogenetic and resistance mechanism in maize stalk and ear rot since initiating " National Eighth Five-Year Project" were reviewed in detail. Some academic opinions about the kinds of dominant pathogens and occurrence pattern of ear and stalk rots were summarized and further discussed, and the preliminary hypothesis about resistance mechanism to stalk rot in maize was described based on recent progresses. The interrelationship between ear rot and stalk rot in etiology and occurrence pattern were explored at home and abroad from different aspects, such as the systemic analysis in infection cycle, serology, soluble protein, and isoenzyme DNA ,which will be destined to strengthen the basis for IPM of the two diseases.
Keywords:maize  ear rot  stalk rot  etiology  resistance mechanism  IP@
