Based on the analysis, the pathogenic rate of the rice Zhe 173 to hybrid medium indicia rice, medium japonica rice and hybrid medium japonica was higher than others.

根据白叶枯病菌不同致病型菌株对参试品种致病率的分布情况分析，浙173菌株对杂交中籼、常规中粳稻和杂交中粳稻的致病率较高。

Experimental sowing with two cultivars was realized combining three inter row distances ( IRD: 0.70m, 0.50m and 0.30m) and two interplant distances (IPD: 0.06 and 0.12m).

试验采用2个品种(分别属于西班牙型和兰娜型)，方式为3种行间距(分别为0.70m、0.50m和0.30m)和2种株间距(分别为0.06m和0.12m)的组合，株行距比值较低(介于0.1和0.4之间)。

Strains M110 and M113 isolated from Aedes albopictus and Armigeres durhami, respectively, which were fatal to suckling mice at 4 days after intracerebrally inoculation and had cytopathologic effects on BHK21 cells, showed a positive reaction to dengue antibody and could be amplified Ly using flavivirus primers and dengue type-4 NS1 gene primers and dengue type-4 NS2a gene primers.

结果 从白纹伊蚊和达勒姆阿蚊中各分离到一株病毒，分别命名为M110和M113，这两株病毒对BHK21细胞能产生明显的细胞病变，脑内接种乳鼠4d左右导致乳鼠死亡。该病毒经血凝、血凝抑制和间接免疫荧光试验提示为黄病毒。分别用黄病毒属特异引物、登革4型病毒NS1和NS2a基因片段特异引物进行RT-PCR扩增、序列测定，证实为登革4型病毒。

It is concluded that the intracutaneous vaccination with the genome DNA of mycobacterium tuberculosis H37Ra strain induces activation of macrophages and generates strong immune responses, and this effect is not significant difference from immunizing with BCG.

结核分枝杆菌国际标准无毒株H37Ra菌株基因组DNA小鼠皮内接种后，能诱导小鼠腹腔巨噬细胞活化并产生较强的抗结核免疫效应，且该效应与卡介苗菌无明显差异。

The results showed that there were intraspecific differences in plant height and stem diameter of tolerant clones, and plant height and stem diameter of sensitive clones decreased significantly.

结果表明：(1)割手密耐性无性系株高和茎径对UV-B辐射响应具有明显的差异；敏感无性系的株高和茎径显著或极显著的下降。

The results indicated that the astaxanthin-hyperproducing strains of oceanic red yeast could be efficiently isolated on the selective medium containing β-ionone.
