分蘖期水分胁迫对水稻生长发育及产量的影响

After success of transplation, the tillering node of the haploid at full-tiller stage were soaked with the solution of 0.04% Colchicine and 1.5% dimethyl sulfoxide at the temperature of 18 ℃ for 6-8 hours, the doubling percentage was 82.9-87.8%.

移栽成活后处于分蘖盛期的单倍体花粉植株，用0.04%秋水仙碱与1.5%二甲基亚砜混合液在18℃条件下浸泡分蘖节6～8小时，加倍成功率可达82.9～87.7%。

Except for the beginning of the stage after fruiting of sand soil, as for the absolute contents of water-soluble carbohydrate which were stored, the base stem was the most, the second was the rhizome, the least was the tillering node.

除了沙土地果后营养初期之外，就贮藏可溶性碳水化合物的绝对含量而言，茎基部占第一位，其次是根茎，最少的是分蘖节。

The potential clone population consist of rhizome buds of 0 age class and tillering node buds of 1 age class, of which 0 age class constitute the majority, 84.8%.

无性系潜在种群是由0龄级的根茎芽和1龄级分蘖株芽所组成，其中以0龄级芽占绝对优势，达84.8%。

S-3307 Treatments decreased IAA content in tillering node, while it largly improve ZT content, which were benifited for tiller appearance.

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。

Analysis of the Generation Mechanism of a Ds-inserted Rice Mutant with Double Tillers at One Tillering Node

水稻Ds插入双分蘖突变体形成机理的分析

Sugar content in the tillering node of wheat was determined with 3.5& Dinitrosalicylic acid colorimetric method ( DNS method) first applied.

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.

我国上市公司净利润小与利润总额的利润逆转现象频频出现。

Over-low parent heterosis is 5.7% in tillering ability.

在分蘖能力上具有负向超亲优势，负向超亲优势率为5.7%。
