烯效唑处理后，分蘖节IAA的含量减少，ZT含量提高，因而有利于分蘖的发生；

The general results showed that tillering node was the most important organ of winter wheat for safely overwintering because of high cold resistant metabolic adaptation and strong ability for material preparations.

总体表现为分蘖节的抗寒代谢适应和物质准备能力最强，是小麦安全越冬的重要器官，对其第二年的返青具有直接影响。

首次应用3.5&二硝基水杨酸比色法（DNS法）测定了小麦分蘖节中糖的含量。

Advances in genetic analysis, location, mapping, cloning, and action mechanism of tillering ( tillering ability and tillering angle) gene in rice are reviewed in this paper.

综述了国内外在水稻分蘖（分蘖力和分蘖角度）基因的遗传分析、定位、克隆及作用机理等方面的研究进展。

Compared with the hybrids of Jin 23A, the hybrids of Xu 29A show a shorter growth duration, a stronger tillering ability, more productive panicles and a higher seed-setting rate, but fewer spikelets per panicle and lighter grains.

与金23A相比，旭29A所配组合生育期较短，分蘖力较强，有效穗较多，结实率较高，但每穗总粒数较少，千粒重较低。

The reason that waxy barley cultivars were formed was due to smaller kernel and increasing kernels per spike and enhancing coefficient of propagation and expansion of its proportion in the population when keeping its intrinsic tillering ability and the yield. 2.

糯大麦品种是糯性突变体在保持原有的分蘖力和不降低产量的情况下，由于籽粒变小、每穗粒数增加、提高了繁殖系数、逐代扩大其在群体中的比例而形成的。

The results showed that the rice variety "Shenyou 1" was appropriate to the application of SRI due to its strong tillering ability, high percentage of ear-bearing tiller, big ear, and high filled-grain percentage.

结果表明：申优1号以其分蘖力强、成穗率高、穗形大、结实率高的特点，适合应用强化栽培技术。

Relative tillering ability, available spike, biomass, and grain yield of P1, P2, F1, and F2, 3 were used to study the genetic development of rice related to phosphorus efficiency with a quantitative genetic model.

利用数量遗传模型对P1、P2、F1、F2,3等4个世代的相对分蘖率、有效穗、生物产量及经济产量等性状进行了遗传分析。

The reason for lower yield of scatter way was that the bigger tillering ability in earlier stages increased amounts of population, which weakened dry matter accumulation of individual and reduced the number of grains and kernel weight.

撒播减产的原因主要是前期过高的分蘖力导致群体数量增加，降低了个体干物质积累，穗粒数及粒重大幅度下降。

After light planting, the stem become thicker, the tillering ability became strong, the tillering climax was postpone, the superiority place of tillering was lost, the spike rate was increase.

群体变小后，水稻个体茎秆变粗，分蘖力增强，分蘖高峰期推迟，优势蘖位消失，成穗率提高；

By pretreatment with algal extract the height of rice seedlings, number and length of roots, as well as tillering ability, were improved, duration in nursery shortened, leaf area increased.

用藻液处理后水稻幼苗增高，根数、根长增加，分蘖能力增强，秧龄提前，叶面积明显加大。

The daily course of the simulated and measured photosynthesis rates at the top of canopy were in good consistency. The net assimilation rate and tillering ability showed little changes.

对冠层上部净光合作用率日变化过程而言，实测和模拟结果具有较好的一致性。

The net assimilation rate and tillering ability showed little changes. The profit reversion of net profit and total profit in Chinese listed companies has become a frequent phenomena.
