红小豆花前不同叶龄光周期诱导后效应的初步研究

Objective]This article studied the effects of the Photoperiod inducement after-effect at different Leaf ages before flowering in Adzuki Bean, and discuss how to control the development of the crop using the photoperiod after-effect. [Method]Establishing two different photoperiod treatment that is natural light(CK) and 12hour. Until the first couple leaves breaks ground, the treating starts, to observer the growth progress of different treatments, At harvest the yield of each section was measure, and analyzed by Excel. A. [Result]the photoperiod inducement can restrain the height, stem diameter, nodes number, and can forming branching number, and, The photoperiod inducement can effecting the dry matter of accumulation, all the plant are reduce than CK treatment, and younger the leaf ages are, the more distinctness effects are. There into the effects of weight of whole plant and seed is the most obvious. The photoperiod inducement can influence the yield, but the influence between each leaf age is not obvious. The effect of the developing induced by photoperiod is profundity, and younger the leaf ages are, the more distinctness effects are. [Conclusion]the photoperiod inducement can restrain nutrition growing and younger the leaf ages are, the more distinctness effects are, and each leaf age appears accumulation effect, and the effect influence the yield directly, but the disciplinarian at each leaf age needs study next step.
