【摘要】 １９９２ －１９９７ 年对小扁豆花芽分化与结实率进行了研究，结果表明，小扁豆的生长期长，分枝多，花芽分化开始早，分化时间长，分化小花多，前期慢，后期快，当主茎或分枝上某一节位第一朵小花开放以后，位于该节位以下各节位的小花，不论花芽分化到哪一个时期，都开始退化，而上部各节位的小花，随着植株的生长，仍在继续分化，末花期以后再开放的花，基本上都是无效花－ 小扁豆的小花多集中在一级分枝上，其次是主茎更多还原

【Abstract】 The experimental results showed that lentil grows for a longer period with more branches.The bud differentiation begins early with more florets and a longer differentiation period characterized by an early slower differentiation stage and a later faster stage.No matter which stages the florets differentiate in,the florets at various nodes under the nodal site where the first flowered will degenerate on the main stem or branches,but the florets above the nodal site continue to differentiate with plant growing and these flowers opening after later nodal site continue to differentiate with plant growing and these flowers opening after later flowering stage are generally invalid.The florets of lentil mainly concentrate on the first order branches,then on the main stem.更多还原
