摘要
测定不同抗性大豆品种（系）接种ＳＭＶ不同株系后的叶绿素和光合速率，分析它们在大豆不同生育阶段的变化，阐明大豆感染ＳＭＶ后一些光化学活性特点：叶绿素ａ含量减少—叶绿体进行光合作用的原初反应中心受到伤害，光合速率降低，最终引致产量下降。ＳＭＶ对大豆叶绿素、光合速率及产量的影响因品种的抗性及ＳＭＶ毒系的致病力不同而有所差异。
Variations of chlorophyll and photosynthetic rate of soybean cultivars with different resistance were analyzed after inoculated with SMV at different growth stages. Photochemical properties after affected by SMV were pointed out: chlorophyll content reduced; preliminary reaction center of photosynthesis in chloroplast was damaged; photosynthetic rate was decreased. Therefore, the yield of soybean decreased. Variations of chlorophyll, photosynthetic rate and the yield of soybean inoculated with SMV were varied with resistant levels of cultivars and pathogenicity difference of SMV strains.
