摘要
研究了6个甜菜品种的叶绿素含量、叶面积系数、光合生产率和产糖量与抗丛根病的关系。结果表明:病地和无病地上种植抗病品种的叶绿素含量、叶面积系数、光合生产率和产糖量均高于感病品种,这些指标的差异均是生长后期比生长前期明显。
The relations between chlorophyll content ,leaf area index (LAI),photosynthetic productivity and sugar yield with Rhizomania tolerance were studied in six sugar beet strains.The results showed that chlorophyll content ,LAI,photosynthetic productivity and sugar yield of the tolerance strains were all higher than the susceptible strains in disease field or nondisease field,these indices at late growth period were more significant than primary growth period.
