大豆品种感染ＳＭＶ后，感病植株各生育阶段（Ｒ１、Ｒ３、Ｒ５）叶片叶绿素含量、光合速率、单株可溶性总糖含量明显低于健株，表明光合产物累积较少，分配到各器官亦少，使干物质和日积累速度除低，导致表现生物产量下降。就本试验结果分析，表观生物产量的下降是导致感病植株减产的主导因素。
After infected with soybean, the chlorophyll content, photosynthetic rate and total soluble sugar content in leaves of susceptible plants at different growth stages (R1, R3, R5) were significantly lower than those of healthy plants, indicating that photosynthetic products accumulated less and were distributed to various organs Less, in addition to the dry matter and the rate of accumulation of low, leading to the performance of biological decline. Analysis of the results of this experiment shows that the decline of apparent biological yield is the dominant factor leading to the decrease of yield of susceptible plants.
