摘　　要：试验以晋绿9号、冀绿0816为材料,研究绿豆3个生长阶段(开花期、结荚期、成熟期)各器官干物质积累动态变化及分配规律。结果表明,随着生育进程的推进,在植株生长过程中,开花期各植株叶片和茎秆干物质量占全株总干物质量的80%以上;进入花荚盛期,绿豆单株叶片和茎秆干物质量均呈现下降趋势,植株的生长中心逐渐转向生殖器官,生殖器官成为光合产物的主要分配中心,同时营养物质向籽粒运转,到成熟期达到最大值。The paper took Jinlü9 and Jilü0816 as experimental materials,the dynamic changes and distribution law of dry matter accumulation in organs of mung bean at three growth stages(flowering stage,pod setting stage and maturity stage)were studied.The results showed that with the advancement of growth process,the dry matter quality of leaves and stems of each plant in flowering stage accounted for more than 80%of total dry matter quality of whole plant during plant growth.In blooming period,the dry matter quality of leaves and stems of mung bean plant both showed a downward trend.The growth center of plant gradually turned to the reproductive organs.The reproductive organs became the main distribution center of photosynthetic products.At the same time,the nutrients circulated to the grains,reaching the maximum at mature stage.
