In this study, an OsNPR1 rice over-expression vector was constructed and transformed into rice cultivar TP309 and 17 homozygous lines were obtained by self-fertilization and selection. The genetic stability of introduced OsNPR1 in the T3, T4 progenies of homozygous lines was confirmed by PCR. When the transgenic plants were challenged with bacterial blight pathogen Xanthomonas oryzae pv.

构建OsNPR1基因水稻过量表达载体，并将其转化粳稻TP309得到转基因植株；通过自交纯合，得到17个纯合株系；对T3、T4代纯合株系进行PCR鉴定，证实转基因纯合株系中外源OsNPR1基因具有遗传稳定性；检测了T1、T2代转基因株系和T3代转基因纯合株系对水稻白叶枯病病原细菌Xanthomonas oryzaepv。

The improved line persist the main agronomic trait and combining ability of 93-11, show wide spectrum to Xoo strains and enhanced resistance to BB and stem borer. Thus, this line has good prospect in future practical use.

这一遗传改良材料在农艺性状和配合力等方面基本保持了93-11及其杂交组合的主要特征特性，拓宽和增强了其对白叶枯病的抗谱和抗病能力，增加了93-11作为恢复系所配杂交水稻的抗螟虫特性，具有较好的应用前景。

Through selection we obtained transgenic restorer line T773-1 with good agronomic traits and obvious resistance to striped stem borer and herbicide.

3转cry1Ab和bar基因的水稻恢复系T773-1和转Xa21基因的恢复系T773-2进行杂交、自交，对自交世代单株进行cry1Ab、bar和Xa21基因的分子标记辅助选择，获得了带有三基因的恢复系T773，田间种植对水稻白叶枯病、鳞翅目害虫、除草剂具有很好的抗性。

In the Taidong County pond the township paddy rice two term sent the unboiled water in the Republic of China 95 years to stick the insect harm, 97 years one term is for the first time has the spot to fly a louse and the Hu hashish dry sickness harm, the paddy rice sticks the insect for quite to be rare but already the harmful insect which based in Taiwan's paddy field.

台东县池上乡水稻在民国95年二期作首次发生水到粘虫危害、97年一期作则是发生斑飞虱及胡麻叶枯病危害，水稻粘虫为比较罕见但已经在台湾的水稻田立足的害虫。

So, mushroom derived protein amylose 0.5% soluble concentrate biopesticide has good effect on preventing Rice stipe virus, and it also can increase rice production.

因此0.5%菇类蛋白多糖水剂对水稻条纹叶枯病有较好的防治效果，有一定的增产作用。

Studies fabout mushroom derived protein amylose 0.5% soluble concentrate biopesticide on preventing rice stipe virus have been made.

要对0.5%菇类蛋白多糖水剂进行了水稻条纹叶枯病的田间药效试验。

Through investigation and study of the leaf blight disease of Lycium in 5 different areas in Mongolia, the pathogen was identified in-house as Alternaria tenuis Nees, biological characteristics of the pathogens, the bioassay of toxins from A. tenuis Nees, the pathogenic mechanism of toxin and the toxicity determination of the fungicide were studied.

通过对内蒙古5个不同地区枸杞叶枯病的调查研究，确定其致病菌为细链格孢菌，并对该菌的生物学特性、病原菌毒素活性检测、毒素的致病机理及几种药剂的室内毒力进行了研究。

The results showed that:(1)IRBB21 was resistant to all the strains except T7147,astrain from Japan belonging to the Japanese racial group 2,whereas Minghui 63 and 6078 weremoderately susceptible to most of the strains tested;(2) The resistance reactions of the hybrids derivedfrom IRBB21 appeared to be the same as that of IRBB21,whereas that of the hybrids derived fromMinghui 63 and 6078 were more susceptible to BB than the two restorers.

结果表明，IRBB21除不抗日本的T2菌系群外，对所有其它供试菌株均表现高抗，恢复系明恢63和6078对供试菌株多为中感，以明恢63或6078配组的杂交稻的抗性极差，而源于IRBB21的杂交稻的抗性与IRBB21基本相同，因而证实Xa21基因确为在我国极具应用价值的抗性基因，完全可以用于杂交水稻的白叶枯病抗性改良。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
