During the early growth stage of seedlings, basal stem diameter and paripinnate number were decreased with the increasing of shade, taproot length, root : shoot ratio, total dry weight and leaf area per seedling were maximal under 37.3% NS, specific leaf area was increased with the increasing of shade, but the relative growth rate was declined. Seedlings grew fastest under 0.6% NS, suggesting that nutrients stored in seeds played an important role at the early growth stage. The treatment of 37.3% NS was best for established seedlings in seedling height, basal stem diameter, paripinnate number, rachis length, the maximum sub-leaflet number of individual paripinnate, leaf area per seedling, relative growth rate and net assimilation rate. Light intensity was positively correlated to total dry weight, and negatively to specific leaf area. The maximum of SLA was observed under 15.5% NS.

生长早期的幼苗基径和复叶数随遮荫程度的增加而降低；主根长、根冠比、总干重和单株叶面积均以37.3% NS处理最大；比叶面积随遮荫程度的增加而增大，而相对生长率则降低；幼苗株高在0.6% NS下增长最快，表明种子中贮藏的营养物质对幼苗的早期生长可能具有重要作用。37.3% NS处理对定居后绒毛番龙眼幼苗的生长最有利，幼苗的株高、基径、复叶数、叶轴长、复叶最多小叶数、单株叶面积、相对生长率和净同化率均在37.3% NS处理下获得最大增长；幼苗总干重随光照强度的减弱而降低；比叶面积在15.5% NS处理时最大。

This research take late-maturing variety adzuki bean Jihong-4 as the experiment material, After the photoperiod inducement at different leaf ages treatment, the result showed that the activity of NR under LF treatment is higher than CK treatment on the whole, and is lower than SD treatment; The content of the dissociation amino acid under these three treatments show a descend trend along with the leaf ages accretion, but the inducement increasing the content of dissociation amino acid, different leaf ages leaves show some difference, and alternating rise with SD treatment; Inducement can reduce the content of soluble sugar, and continuous inducement shows a accumulation effect; 2LF is the most sensitivity stage for soluble protein under photoperiodic inducement, From this stage, each leaf indumenta can reducing the content soluble protein, but continuous inducement reducing rising it.

本研究通过光周期诱导的方法，对中晚熟品种冀红4号红小豆进行不同叶龄进行处理，结果表明：所有叶龄处理下硝酸还原酶活性基本高于自然光处理而低于连续短日照处理下的；随着叶龄增大，各处理游离氨基酸总量均呈下降趋势，但光周期诱导可提高游离氨基酸含量，不同叶龄表现有所差异，与连续诱导交替上升；诱导可降低可溶性糖的含量，并连续诱导出现累积效应；2LF是光周期诱对可溶性蛋变化最敏感的时期，这个时期起单个叶龄诱导可降低可溶性蛋白含量，但连续诱导却可提高；LF处理下的类胡萝素总体含量高于另两个处理，而LF处理下的叶绿素含量在仅3叶龄前高于CK处理下的，随后出现下降趋势。
