Methods: According to the conserved regions of three genes reported, three pairs of specific primers were designed and used to amplify them from genomic DNA of soft hexaploid Chinese spring＇ s young leaves, Results: Through gene cloning and sequencing, they were 447bp, 447bp and 495bp in size, encoding 148, 148 and 164 amino acid residues respectively.

根据已报导的小麦3种基因的保守序列，设计合成了3对特异性引物，对六倍体软质小麦中国春基因组DNA进行基因扩增、克隆和序列测定，得到了3个基因的全长。

We designed several treatments according to different illumination intervals after 72h darkness, light intensity, and nitrogen fertilizer on two wheat species, and an enzyme linked immunosorbtion assay was developed for the measurement of Rubisco and Rubisco activase in horsebean, corn and rape leaves.

对两个不同品种的盆栽小麦进行不同光照和施氮水平处理，并提取其粗酶液，按照上述最佳工作浓度分别稀释该粗酶液以及相应的多克隆抗体，通过ELISA测定小麦叶片中的Rubisco及其活化酶含量。

Through identification of all F 1, F 2 and partial BC 1, BC 2 resistance to wheat spindle streak mosaic disease and tracing analysis of F 3, the heritability of resistance to WSSM was studied in the wheat varieties.

本试验选用17个高抗品种、9个高感品种随机组合进行杂交，通过对F 1、F 2和部分BC 1、BC 2的抗感鉴定结果以及F 3代的追踪分析，研究了小麦品种对小麦梭条花叶病的抗性遗传规律。

There are bands of Triticum and Elytrigia in Tritielytrigia, they are new octoploid types that be different from Triticum and Elytrigia.

小偃麦兼有小麦和天蓝偃麦草的酶带，是不同于小麦和天蓝偃麦草的八倍体新类型。5个小偃麦划分成两种不同的类型，中_1和中_2属于第一种类型，中_3、中_4和中_5属于第二种类型。

The spikes per plant of diploid and tetraploidspecies were higher, but the kernels per spike, 1000 kernels weight and grain yield werelower than those of hexaploid and octoploid species. The NYE, NHI and NPE of diploidand tetraploid were lower; NDE was higher than these of Hexaploid. Variation of NPE andNYE was higher than other NUE indexes, which indicated that NPE and NYE could beused as indexes for NUE differences in different wheat related species.

与普通小麦相比，二倍体和四倍体材料单株穗数较多，但穗粒数、千粒重和产量比较低；氮素籽粒生产效率、氮素收获指数和生理效率比较低，具有较高的氮素干物质生产能力；NYE和NPE的变异性较大，可以作为小麦不同近缘种氮素利用效率差异的主要指标。

VDE activities from leaves of wheat cultivars with different photooxidation tolerance were also investigated under weak and strong light.

以小麦为试验材料，研究了紫黄质脱环氧化酶的催化特性，以及不同光氧化抗性的小麦品种在强光和弱光下的VDE活性。

SA could significantly increase the activity of SOD enzyme and the content of praline, decrease the content of MDA, reduce the cell damage caused by low temperature and enhance cold resistance of wheat seedling.

结论］SA显著提高小麦幼苗细胞内SOD酶的活性，增加脯氨酸含量，降低MDA含量，减少了低温对细胞的伤害，增强了小麦幼苗的抗寒性。

The hereditary behavior of bar gene in T1 and T2 generated by self-fertilization of bar-transgenic wheats-wanmai48 and ymai87158 was studied. Effects on agronomic traits of bar gene were also researched.

以皖麦48和扬麦87158两个小麦品种的转bar基因株系为材料，探讨bar基因在转基因小麦自交后代的遗传表现及对农艺性状的影响。

Data of 14 weather factors during 1933~2000 are studied by using stepwise regression analysis.

因此，做好小麦吸浆虫发生的预测预报工作，对指导小麦吸浆虫的防治工作有着十分重要的作用。

The stimulations of wheat tonoplast H +\|ATPase by both Mg 2+ and Ca 2+ were measured on the base of purification of the enzyme.

纯化小麦液泡膜H+-ATPase，测定了纯化的小麦液泡膜H+-ATPase 受Mg2+和Ca2+双重激活的特性及两种激活状态下酶的特性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
