The results showed that all contents were lower in male sterilie anthers than in fertilisable ones.With anther developing,the contents of soluble starch,protein and free proline increased obviously in male fertilizable anthers,but not in sterile ones.

结果表明：太空诱变处理玉米核不育材料的可育株花药中的可溶性糖、淀粉、蛋白质以及游离脯氨酸含量均高于不育株花药的，且可育株花药中的可溶性淀粉、蛋白质和脯氨酸含量都随着花药的发育逐渐累积，在不育株花药中这些指标的变化不明显。

So in our test aantagonistic germ was isolated from ginger soil and was studied. 108 strains of germs were isolated by tube dilution assay from the soil of gingerin Qingmu town,Bazhong city. Q6 strain was screened from these strains of germsthough the first screened and rescreened double with deck agar method andimproved aperture-strikeing method.

本实验从巴中市青木镇堆放腐烂姜并且又长出健康姜苗的根际土中分离出106株细菌，在涂布有姜瘟病原菌青枯劳尔氏菌的肉汤培养基上进行初筛，得到6株对青枯劳尔氏菌有较强拮抗作用的细菌，通过摇瓶发酵后利用发酵液，采用改良的琼脂孔扩散实验复筛，获得一株具有强拮抗作用的菌株，命名为Q6号。

Four field strains of infectious bronchitis viruswere isolated from chicken kidney, trachea and lung of the young layer flocks in some regions of Shaanxi province. Biological characterizations of the virus were investigated by virus pathogenicity to chicken embryo and healthy chickens, hemagglutination test, hemagglutination inhibition test, dwarfing embryonated chicken eggs, electron microscopy and reverse transcription polymerase chain reaction. It demonstrated that allantoic fluid of each passage virus could hemagglutinate chicken red blood cells by treatment with 1% trypsin. The standard positive serum to IBV could inhibited the hemagglutination. The isolates could make respiratory and kidney diseases in chickens.

采集陕西省宝鸡市、扶风县、兴平市和榆林市等地鸡场疑似传染性支气管炎发病鸡病料，通过9～11 日龄非免疫鸡胚进行了病毒的实验室分离和传代，并对分离毒株进行了病毒的血凝性、血凝抑制性、致病性、鸡胚矮小化、电镜特征等生物学特性鉴定，结果表明，4 株分离株经1%胰酶处理后的各代病毒尿囊液均可凝集鸡红细胞，标准阳性血清可特异性的抑制其凝集性，回归试验可复制出与自然发病相同的病例，病毒传代物有明显的致鸡胚矮小化作用，透射电镜下可见有近似球形、直径100 nm左右的冠状病毒粒子，将分离鉴定的4 株IBV 定名为BJ-04、FF-04、XP-03 和YL-04。

The results showed that the lactic acid bacteria were belongs to those special homotype fermention types of Lactobacillus.9 strains belong to Lactobacillus gasseri, one does Lactobacillus.salivarius and the other 9strains do Lactobacillus.crispatus.

其中1-1、1-2、1-3、1-7、51-1、51-4、52-1-1、52-1-2、52-3 共9 株为格氏乳杆菌， 23-2-1 为唾液乳杆菌(Lactobacillus.salivarius)，23-2-2、23-4、23-5、23-8、32-3、46-1、46-2、46-3、50-3 共9 株为卷曲乳杆菌(Lactobacillus.crispatus)。这19 株乳杆菌发酵过程中都产生细菌素，除了32-3，51-1，51-4 这3 株菌外，都产生过氧化氢。

Prain, Trifolium repens Lam, Aeachynomene Mica L, Indigofera bungeana Steud.The same strains used in numerical taxonomy were analysed by BOXAIR-PCR fingerprinting. All tested strains were clustered into 47 groups at the similarity level of 50%. Compared with the result of numerical taxonomy, strains belonged to one phenon in numerical taxonomy always distributed into several BOXAIR-PCR groups, most of reference strains come from one recognized rhizobial species were not grouped together.

B(来源：dd9dAB94C论文网www.abclunwen.com)OXAIR-PCR指纹图谱的聚类结果显示：全部供试菌株在50％的相似性水平上分为47群，与数值分类的结果相比较，其分群的结果更分散，在数值分类80％相似性水平上位于同一表观群的供试未知菌株大多分布于几个综合的BOXAIR-PCR群内；另外在数值分类中来自同一个种的已知根瘤菌参比菌株几乎都聚在同一个表观群，而在BOXAIR-PCR分析中，已知参比根瘤菌的同一个种内的大部分菌株都单独成群。

Up to date, QTL analysis of adult-plant resistance against powdery mildew has not been reported in China. In the present study, QTL mapping of APR was conducted using a doubled-haploid population derived from the cross (Fukuho-komugi × Oligoculm) and a F_(2:3) population from the cross (Bainong64 × Jingshuang16). The methods and main results are described as follows:1. A doubled-haploid population from an intervarietal cross between the Japannese cultivar Fukuho-kumugi and the Israeli wheat line Oligoculm was prouduced by means of wheat × maize crosses.
