In order to explore the chemical regulation of the plant type dwarfing of Coleus blumei, its cutting plantlets were used as the experimental materials in this research. Through studying its height and cytological characters of each treatment, we found that spraying 800-fold liquor of 15% Paclobutrazol wettable powder and 7,000-fold liquor of 5% Unlconazole (S3307D) on its leaves had significant dwarfing effect on it; 400-fold liquor of 50% chlormequat chloride had not any.

为了探索彩叶草株型矮化的化学控制，以其扦插幼苗为材料，通过对其株高及其细胞学特性研究，发现叶面喷施15%多效唑可湿性粉剂800倍液和5%烯效唑可湿性粉剂7000倍液对彩叶草株型具有显著的矮化作用；叶面喷施50%CCC水剂400倍液，矮化效果不显著。

The coppiced shrub remained two coppice shoots adding the parameters obviously of the number, the total length,1 the biomass of new branch and the number and biomass of leaf. 3. the leaf area decreasing with the increasing of adjusting degree.

在相同的生境下，三种调控措施中对基径、顶梢生长影响最明显的是2克隆株/丛与3克隆株/丛；2克隆株/丛的调控措施明显增加当年新生枝的数量、总长度、生物量以及叶片的数量和生物量；而叶面积随调控措施程度的增加有逐渐减小的趋势。

Then they were identified by serum plate agglutining test, HI test and serotype-specific monocolonal antibody. The results showed that 15 isolates among them were serotype A, and 4 isolates were serovar B. This results indicates that there are some new epidemiological characteristics of infectious coryza in china.

又将分离株用血清平板凝集试验、血凝抑制试验和型特异性单抗进行了血清型的鉴定，结果表明分离菌有15株为A型，4株为B型，说明我国鸡传染性鼻炎的流行已经出现了新的特点，在疾病预防和控制中应加以注意。

All of the P. multocida strains generated positive signal, and no cross-reaction was observed with non-P, multocida strains in the PCR detection.

结果表明：所有的多杀巴斯德氏菌标准菌株和分离菌株都能被检出，而全部39株非多杀巴斯德氏菌都没有扩增出特异性条带。

Preventing and controlling crown gall disease applied the early biological controls strain K84, itself did not have the pathogenicity, its plasmid may synthesize one kind of bacteriocin Agrocin84, may suppress many pathogenic strains, but did not have pathogenicity to non-pathogenic strain .

防治根癌病应用较早的生防菌株是K84，本身无致病性，它的质粒可以合成一种细菌素Agrocin84，可以抑制很多有致病性的菌株，而对非致病性的菌株则无影响。

Among pesticides insecticides exhibited best compatibility,then herbicides,the last was fungicides.The process of mycelium of SYAU-06 strain infection to dayflower leaf was observed under light and electronic microscope.

结果表明杀虫剂与SYAU-06菌株的相容性最好，杀菌剂与SYAU-06菌株完全不相容，除草剂与SYAU-06菌株的相容性介于杀虫剂和杀菌剂之间。3。

The research included host range,biological characteristics,infection process and infection influence factors of SYAU-06 strain as well as the herbicidal activity,extraction technology,action mechanism,biological safety,separation and purification technology and structure elucidation of phytoxin produced by the strain.The experiment provided a new method to biocontrol dayflower.

通过对SYAU-06活体菌株的寄主范围、生物学特性、侵染过程、侵染影响因子和毒素的除草活性、提取工艺、作用机理、生物安全性、分离提纯技术研究以及结构解析，从活体菌株和毒素两个方面系统评价了SYAU-06菌株防除鸭跖草的潜力，为鸭跖草的生物防治提供新的方法和思路。1。

The main regions (405-1 146 nt) in the glyco pro tein gene of 8202,BRV and MRV,isolated from deer,cattle and mouse in China re spectively,of rabies virus was amplified by reverse transcriptase-polymerase ch ain reaction,cloned and sequenced.

对来源于鹿、牛和鼠的狂犬病病毒野毒株82 02、BRV、MRV的G基因405～1 146位核苷酸序列进行了RT-PCR扩增、克隆和序列测定，并应用计算机软件对这3个毒株的测定序列和人源株CGX89的相应序列进行了分析比较。

Result The three strains all produced the AHL signal molecules; the strains FML05-land FML05-2 produced two types of AHLs at least and the N-3-oxo-octanoyl-homoserine lactone was the predominant signal molecules. The production of siderophore and proteinase in FML05-2 were reduced by co-incubation with AHL degrader strain.

结果］3株菌均产生AHLs信号分子；菌株FML05-1、FML05-2至少产生两种AHLs分子，二者所产生的主要信号分子是N-3-氧代－辛酰基－高丝氨酸内酯(N-3-oxo-C8-HSL)；FML05-2与降解AHLs的菌株共同培养，发现嗜铁素的产量与蛋白酶活性明显下降。

PartⅡTransform the yeast, screen the excellent expression yeast strain, induce the yeast to express the fusion protein and depurate the target protein. The recombination plasmid was transformed into the yeast GS115 successfully by means of electrotransformation. The excellent yeast strain was got by G418 screening. We achived the yeast supernatant including target protein induced by methanol.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
