The above three soybean varieties were treated with short-day of 12 h and long-day of 16 h in whole growth period, the different photoperiod treatments changed development process, podding-habits, plant morphogeny, and agronomical characters of different types of stem termination. And by this method photoperiod-sensitive and photoperiod-insensitive soybeans were divided, which is an important meaning at the production and popularization of soybean varieties.

对以上三个不同结荚习性品种进行两种较为极端的全生育期光照处理，短日照处理(12小时)和长日照处理(16小时)均可不同程度地影响不同茎顶类型品种的生育进程、结荚习性、株型和其他农艺性状，并且以此方法可区分出光敏感性相对较强和较弱的品种，对品种的生产和推广有一定的指导意义。

The main results were as follows:An appropriate concentration of ethephon sprayed on leaves of peanut made stems and branchs height shorter,but more branches;The fresh weight and dry weight per unit of leaf area and per plant increased;It optimized some physiological and biochemical characteristics in the leaves.It was showed that the ethephon increased obviously the contents of protein and chlorophyll and the activity of SOD and POD in the leaves,and improved the rates of photosynthesis and transpiration of the leaves,and increased the activity of the roots,but decreased the content of MDA in the leaves;It improved the quantity of pods,the percentage of plumy pods and the peanut yield.

结果表明：喷施适宜浓度的乙烯利可使植株相对矮化，抑制花生地上部分的生长，使主茎和分枝长比对照短，但分枝数较多；提高单位叶面积鲜重、干重以及植株鲜重、干重；优化花生植株的生理生化特性，表现为显著提高了花生叶片的蛋白质含量和叶绿素含量及SOD和POD活性，增强了花生叶片的光合速率和蒸腾速率，增强了主根活力，降低了花生叶片的丙二醛和可溶性糖含量；提高植株的单株结荚数、饱果率和产量。
