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。

Stem and Dongmu-70 rye grass (Secale cereale L.) stem. The diameter, length, weight and linear density of stem were measured after sample collection. Shearing force was measured.
