1) grain/plumpness
谷粒/充实度
2) grain plumpness
谷粒充实度
1.
Although N application of spikelet promoting,spikelet sustaining or redundant fertilization would result in high grain plumpness, the size of hull was reduced, so that grain weight were also dropped.
结果表明 :与不施肥相比 ,施用基肥可促进谷壳伸长增宽 ,谷壳投影面积增加 ;施用促花肥、保花肥或在施用分蘖肥的基础上过多施用穗粒肥 ,虽可增加谷粒的充实度 ,但谷壳长度、宽度和投影面积变小 ,粒重下降 ;施用分蘖肥可促进谷壳增大 ,对谷粒充实度的影响因品种而异 ;谷壳投影面积与粒重关系密切 (r9516 =0 。
2.
Grain plumpness decreased by low temperature treatment during booting and grain filling period, and the visible effect of grain plumpness were founded from sixteen to twenty days after heading.
灌浆期低温明显地降低了谷粒充实度,其中抽穗后16~20d的处理,谷粒充实度下降幅度最大。
3) grain/filling
谷粒/充实
4) Grain plumpness
籽粒充实度
1.

3.
The genetic analysis was made on grain plumpness of hybrids in indica japonica lines(IJLs) with different genetic differentiation mated with indica photo thermo sensitive male genetic sterile lines (PTMGS).
利用 4个不同遗传背景的籼粳型品系及 1个粳型广亲和品种与籼型光温敏不育系配组杂交 ,对籽粒充实度进行遗传分析。
5) Inferior grain plumpness
弱势粒充实度
6) grain filling
籽粒充实
1.
With two-line hybrid rice Yangliangyou 6 and Liangyoupeijiu and three-line hybrid rice Shanyou 63 as materials, the relationships of source, sink and flow with grain filling were studied.
以两系杂交稻扬两优6号和两优培九及三系杂交稻汕优63为材料,研究了源、库、流特征及其与籽粒充实的关系。
2.
Progress on research of rice population was summarized, which includes yield production,grain filling,source sink characteristic and optimizing control on rice population.
分群体产量生产、群体籽粒充实、群体源库特征和群体优化调控等 4个方面 ,对我国水稻群体研究的新进展进行了综述 ,并提出了未来水稻群体研究的 10个方
3.
