With the increase of the carbon dioxide density to enhance the impact on the wheat conductivity and the MAD density, the rise in the CO2 density causes the reduction of the exosmosis conductivity and the increase of the MDA content, the change of which is the same as the exosmosis conductivity.

第三部分是CO2浓度升高对小麦叶片活性氧的影响，再次增加二氧化碳浓度进行实验，观察小麦H2O2含量和超氧负离子自由基的影响，得到的结果是高浓度二氧化碳可以降低小麦叶片中活性氧的含量，因而能够减轻H2O2的毒害作用。

With rye cultivar AR71 as the source of resistance to wheat sharp eyespot,we tried to transfer the rye resistant genes into eight wheat cultivars or lines by pollen tube pathwaymethod and intergeneric crossing between wheat and rye.

The system could provide the real-time information on occurrence of more than 60 different kinds of diseases and pests in wheat, corn, rice, potato, sorghum and millet of China as well as diagnosing, knowledge providing and short-term controlling decision for nine kinds of important diseases and insect pests, including powdery mildew, sharp eyespot and scab of wheat, rice blast, rice false smut, potato late blight, aphids, grain gall midge of wheat and corn borer, based on crop resistance, primary level of pests and short-term weather forecast.

本系统能够对小麦、玉米、水稻、马铃薯、高粱和谷子6种主要粮食作物的60余种病虫害进行实时监测、预警、诊断、提供植保知识，能够对年度间同期病情、虫情做出图形比较，可将抽象的预警数据转化成清晰简明的点图式电子地图，直观明了地显示病虫害发生点数及地域分布，可根据品种的抗病虫性、病虫害发生基数和未来天气预报等信息对小麦白粉病、赤霉病、纹枯病、稻瘟病、稻曲病、马铃薯晚疫病、麦蚜、小麦吸浆虫和玉米螟9种重要病虫害做出短期防治决策，系统的运行有助于提高人们对主要粮食作物病虫害管理的科学水平。

The results show that under crop rotation of wheat and maize in damp soil and brown soil, stalks return to fields integrated with applying potash fertilizer can keep K balance within a cycle and K return rate reaches 109.1%～111.9%, annual wheat stalks return to fields can provide 226.5～261.0 kg/hm2 K, meanwhile the K return rate reaches 95.2%～97.1% for only applying potash fertilizer; under crop rotation of wheat and soy bean in grittiness black earth, only applying potash fertilizer can also keep K balance within a cycle, its K return rate reaches 119.9%, meanwhile the K return rate reaches 142.0% for stalks return to fields integrated with applying potash fertilizer, which result from maize being much more absorption to K than soy bean.

在砂姜黑土区小麦+大豆轮作制度下，即使小麦秸秆不还田，仅施用化学钾肥，亦能维持小麦-大豆轮作周期钾素的平衡。施钾配合秸秆还田处理，钾归还率达142.0%，施钾且秸秆不还田处理钾归还率达119.9%。主要是大豆不象玉米那样带走较多的钾造成的。

The study suggest:(1) The observation of satellites in root tip and multiplex PCR makers could accurately identify the homozygous and the heterozygosis of 1BL/1RS translocation.(2) Through the restoring degree we could confirm the success of the transfer. The combination of the restoring degree and the agronomy property could increase the efficiency of practical application.(3) This study proposed the transformation from the physiological male sterile to the genetic male sterile, and then establish a method of utilize the strong superiority crosses.

其中复合引物PCR更适合于回交后代中大量目标种子的筛选；(2)恢复基因转育后代定株与不育系测交，依据测交恢复度可准确确定恢复基因在回交后代的延续，恢复基因定株定向转育与性状选择结合可大大提高转育后代的实际应用效果；(3)本研究提出的粘类小麦雄性不育恢复基因Rfv1定向转育体系，可有效地实现小麦由化控强优势组合向三系强优势组合的定向转化，即生理型不育途径向遗传型不育途径的定向转化，进而建拓一套杂交小麦强优势组合多途径利用新体系。

This study indicate that improved photosynthetic capacity, water use efficiency are bases for enhancing grain yield with evolution from diploid to hexaploid wheat.

因此，小麦长期进化过程中，六倍体小麦花后较强的光合能力和较高的水分利用效率是提高小麦产量的重要生理基础。

In this study, the TaDREB1 gene sequences were isolated from four hexaploid wheat cultivars, three diploid relative-species and one tetraploid relative-species.

本研究旨在开发TaDREB1基因的SNP标记，同时摸索一种在普通小麦中开发SNP标记的可行方法，为加密小麦的遗传连锁图谱，发掘和利用小麦的优异抗旱种质资源提供一条新途径。

According to Mather and Jinks model, using generations mean analysis m eth od, the various kinds of gene effects and its percentage of gene-effect-square s um were estimated,and comparative analysis on the gene effects and the importan ce t o inheritance of characters was carried out between the supernumerary spikelet l ines.

黄毅以主穗小穗数在25～30个的二个普通小麦多小穗品系85DH5015、SW94-30921 与三个普通小麦品种组配成6个组合的P1、P2、F1、F2、B1、B2为材料，用世代均值法分析了6个性状的遗传模型并估算了各类基因效应值，比较分析了两个不同来源多小穗小麦品系六个性状各类基因效应的异同及其相对重要性。

It had broken out many times on our country history, and has great impact on wheat yield. Therefore, the forecasting of wheat midge is very important to the control of wheat midge.

小麦吸浆虫对小麦可造成毁灭性灾害，在我国历史上曾多次爆发，本世纪50年代、80年代猖獗危害。90年代以来，每年仍在部分地区猖獗危害，对小麦生产造成了较大的影响。
