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.

In the present study, the autotetraploid rice IR36-4X was treated with ion implantation technique by nitrogen ion beams and a polyembryonic seedling mutant (named as the IR36-Shuang) was identified in M2 generation. The mutant line was systematically investigated about the location of seedling in polyembryonic seedling, and the cytological initiation of the additional embryo in the 1R36-Shuang was observed and determined.

Additionally, species with larger plasticity in biomass allocation and relative growth rate also showed higher seedling survival rate.7 All these suggested that higher light availability in grazed disturbed meadow community favor seedling recruitment for these familiar forbs component species, but bottom shade in fertilized meadow community restrain seedling recruitment for these species.
