1)  grain filling
谷粒充实
1.
Compared with CK(no N application),N applied as basal dressing was beneficial to hull enlargement,N applied as granulated fertilizer contributed to high grain plumpness,and N applied at tillering stage was conductive not only to hull enlargement,but also to grain filling,so that grain weight were increased.
设计基肥、分蘖肥、促花肥、保花肥、粒肥等 7个施氮期处理 ,研究其对“扬稻 6号”谷壳生长、谷粒充实及粒重的影响。
2)  grain/filling
谷粒/充实
3)  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 。
4)  Grain plumpness
谷粒充实率
5)  grain/plumpness
谷粒/充实度
6)  grain
谷粒
1.
They are (1) method by evaluating percentage of clipped remnant stigma; (2) method by identifying morphology of remnant anthers; (3) method by difference of purple expression in sheath and (4) method by appraisal of ordinary grain morphology.
介绍杂交稻种子纯度的形态鉴定方法研究进展概况,对柱头残迹夹持率、花药残迹形态、芽鞘显紫差异、谷粒形态等四种形态鉴定方法进行评介。
