| 摘 要： | 为明确光周期处理对小豆花器官关键生理生化指标及产量构成影响,以晚熟品种唐山红小豆为试材,根据小豆不同花芽分化时期,设置1个自然光处理和3个12 h光周期处理。CK:自然光处理;SD1:生长锥肥大期至花序节苞叶及枝梗分化期遮光;SD2:小花分化期遮光;SD3:雌雄蕊分化期至花器官完成期遮光。结果表明,与对照相比,可溶性蛋白含量在盛花期至盛荚期,遮光处理不利于含量增加;在始粒期则相反。在始荚期可溶性糖含量各处理间差异显著,与对照相比,结荚期光周期处理有利于增加可溶性糖含量,而抑制可溶性淀粉含量。遮光处理对硝态氮含量影响不显著。与对照相比,SD3处理显著增加游离氨基酸含量。光周期处理抑制花器官生理生化指标含量增加,但影响不明显,其中SD3处理有利于氮代谢,抑制碳代谢。光周期处理对单株分枝数、主茎节数、节间长度影响比对株高、平均茎粗更明显;对单株荚数、单荚粒数、单荚粒重影响比对百粒重更明显。SD3处理促进产量提高。

| Abstract: | In order to clarified the effects of short-day photoperiod on the vital physiological and biochemical index?of flower organ and yield of adzuki bean. Proceeding 12 h shading treatment in different flower bud differentiation period of the late-maturing adzuki bean of TangShan. Setting up a natural light treatment and three 12 h shading treatment. CK: natural light, SD1: the growth cone loose to inflorescence bract and branch differentiation. SD2: floret differentiation stage. SD3: differentiation of pistils and stamens to mature. The results showed that shading treatment is not conducive to increasing the content of soluble protein from full-bloom stage to full-pod stage, compared to the control, and can increase the content of soluble protein in beginning grain. For soluble sugar, The significant difference between the four treatments in beginning pod stage. Compared to the control, the shading treatment can increase the content of soluble sugar and is not conducive to increasing the content of soluble starch in beginning pod stage. Effect of shading treatment on the content of Nitrate Nitrogen is not significant. Compared to the control, SD3 treatment can increase the content of free amino acid significantly. Photoperiod treatments inhibited the content of physiological and biochemical indexes of floral organ, but the effect is not obvious. The SD3 treatment is beneficial to nitrogen metabolism and not carbon metabolism. The shading treatment effects on plant branch number, node number and internode length than plant height and average stem diameter is more obvious. The shading treatment effects on pod number per plant , grain number per pod and seed weight per pod than hundred-grain weight is more obvious. SD3 treatment to promote production increase. |
