2004年岑溪市晚稻大面积稻发生穗包颈主要原因是由于播种偏迟，幼穗分化期遇高温干旱，抽穗时又持续3d的低温伤害。

The incomplete panicle exertion occurred over large area in late cropping rice in Cenxi city was caused due to later sowing time , emergency of high temperature in young panicle differentiation stage and three days low temperature during heading stage .

利用cDNA-AFLP技术分析了强优势和弱优势组合在幼穗分化至抽穗的叶片基因表达差异，获得了35个差异表达片段。

Differential gene expression patterns during the panicle development stage were analyzed by cDNA-AFLP technique and 35 differential fragments were obtained .

水稻幼穗分化期叶片含氮量与穗粒数呈正相关关系（P0.01），与成穗率呈显著负相关，这可能是导致农民习惯施肥成穗率低的原因之一。

There was a significant negative correlation between leaf nitrogen content during panicle initiation period and spike rate , which was one of the reasons that led to the low spike rate in FFP treatment .

结果表明，水稻对Cd胁迫的反应因生育期不同而异，幼穗分化之前（前期），镉毒害主要表现为降低光合生产力；

Results showed that there were different responses of rice plants on Cd exposure in various growth stages . In the stage before spikelet initiation ( the early stage ), the major response of Cd toxicity was the reduction of photosynthetic potential .

结果表明，在幼穗分化阶段，两品种GA3和ZR含量对幼穗分化进程影响较大，IAA和ABA含量较低且变化较小，主要通过激素平衡影响幼穗分化。

During the spike differentiation , the contents of GA 3 and ZR had larger effect on the process of spike differentiation than those of IAA and ABA , which were low and stable , and affected spike differentiation through the balance of hormones .

结果表明，春小麦幼穗分化开始于出苗后的11～16d，穗分化全过程持续32～41d，不同品种之间以及同一品种在不同水肥条件下均存在较大差异。

The results showed that spike began to differentiate from the eleventh day to sixteenth day after emergence , and lasted 32-41 days and there were differences among different varieties .

单位面积高的有效穗数为基于产量选择组高产奠定了基础。（3）不同基因型组之间水稻幼穗分化期LAI和CGR无显著差异。

So , higher effective tiller number was the fundamental to higher yield in yield-based selection compared with that in trait-based selection . ( 3 ) There was no significant difference in LAI and CGR among the four genotypic groups at the panicle initiation stage .

结果表明，营养生长期（移栽至幼穗分化）、生殖生长期（幼穗分化至抽穗）及抽穗成熟期的UVB处理对Sasanishiki的产量及其构成因素的影响不显著；

Differences in yield and yield components were not significant between the control and the UV-B treatments during the vegetative stage ( from transplanting to panicle forming ), reproductive stage ( from panicle forming to heading ) and flowering-ripening stage ( from heading to ripening ) .
