In this paper, male sterile line of alfalfa was used to be improved with crossing, because the seed production of crossing is low. The affecting factors of seed production of male sterile line of alfalfa and its crossing progenies that are crossed with male sterile lines of alfalfa and good alfalfa that male is fertile were analyzed. The characteristics of female reproductive organs of male sterile line and its crossing progenies are analyzed in cell morphology. The genetic difference of male sterile line and its crossing progenies are analyzed in enzyme protein. The results showed: 1、Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plant BC1-2 that is the crossing progency of male sterile line of alfalfa and Medicago varia Martin.cv.'Caoyuan No.1'is higher than male sterile lines. Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plants BC1-19、BC1-21、BC1-22、BC1-23 that are the crossing progencies of male sterile line of alfalfa and Medicago sativa L.cv.

针对苜蓿雄性不育系杂交制种产量低的问题，采用杂交法对苜蓿雄性不育系进行改良，以原苜蓿雄性不育系为轮回亲本与雄性可育优良苜蓿品种杂交，分析苜蓿雄性不育系及其杂交后代种子产量的影响因素，从细胞形态学方面观察和分析杂交后代及原不育系在雌性生殖器官上的变异特点，从酶蛋白水平对杂交后代及原不育系的遗传差异进行分析，初步研究结果如下： 1、苜蓿雄性不育系与草原一号苜蓿的杂交后代不育株BC1-2，以及苜蓿雄性不育系与X′(苜蓿雄性不育系与新疆大叶苜蓿的杂种F1代)的杂交后代不育株BC1-19、BC1-21、BC1-22、BC1-23的天然杂交结荚率和人工杂交制种的结荚率和百粒重均高于原苜蓿雄性不育系。

To analyze effect of diclazuril and maduramycin on 18S rDNA of Eimeria tenella, the 18S rDNA of sporulated oocyst of the E. tenella anti-diclazuril strain, the E. tenellaanti-maduramycin strain and the E. tenella drug-sensitive strain were cloned and sequenced, and were compared by using DNAStar 5.0 and RNADraw 1.1, respectively.

Soil-aggregate mixture is composed of gravel or cobble as its coarse grain and clay or sand as its filling. Whether natural or man-made, the mechanical properties of this material are widely different from homogeneous and continuous soil or rock.

土石混合体是由作为骨料的砾石或卵石与作为填充料的黏土或砂土组成的特殊工程地质材料，无论天然形成或人工合成，其力学特性与均质土体或岩体相比均有较大差异。

Methods Basolateral amygdala slices of rats were prepared. Field excitatory post-synaptic potentials of BLA were recorded by stimulating the external capsule. Two TBS's were applied to induce LTP in BLA. Each TBS included a brief, high-frequency pulse train (5 pulses at 100 Hz) given at the theta-rhythm (5Hz) for 4 seconds. Experiments compare the effects of different intervals of two TBS's on the expression of LTP in BLA.

制备杏仁核脑片，刺激外囊记录BLA场电位，应用两串θ频率波刺激诱导LTP，每串θ频率波刺激为20个(频率5Hz)短时间高频串脉冲(5个脉冲，频率为100Hz)，通过改变两串θ频率波的刺激间隔，分析不同参数诱导的LTP是否存在差异，并在灌流的人工脑脊液中加入TPK抑制剂genistein，观察其对杏仁核LTP的影响。

The gene effect difference of maize variety Mo17 which is an important resistant germ plasm to maize head smut is studied in this experiment in various susceptible backgrounds on condition of manual inoculation.

The investigations found that there were obviously different in the species richness and individual abundance in the different sampling site. The number of species and the quantity of individual collected from the littoral zone were much higher than those from the open area. The protozoan colonizing rate on PFU in the littoral zone was also significantly higher than that in the open water.

研究结果表明：（1）湖中敞水区和沿岸带原生动物种类数和个体丰度存在较明显差异，前者低于后者；（2）同一生境条件下PFU人工基质收集的原生动物种类多于采自自然基质的种类；（3）定量数据显示该湖原生动物个体数量秋、冬季在每升水中440—180个个体之间波动，较少的个体丰度与该湖属寡营养型特征有关。
