摘要
用春种夏收和夏播秋收块茎作种,比春种秋收块茎作种的L_1代植株叶面积指数高、衰老晚、光合效率高,田间病株率减少56％,Y病毒带毒株率减少50％和97.5％,块茎增产6.9％和18.2％。夏播秋收块茎作种,表现了更高的优势。
Both spring-planting summer-harvesting and summer-planting autumn-harvesting potato tubers used as seed resulted in higer leaf area index of L_1 generation planss, later senescence and higher photosynthetic efficiency than springplanting autumn-harvesting ones. The diseased plant percentage in the field decreased by 56%, Y virus-bearing plant percentage decreased by 50％ and 97.5％ respectively, and tuber yield increased by 6.9％ and 18.2％ respectively. Summerplanting autumn-harvesting seed tubers had higher superiority.
