抗病

The results showed the resistance was controlled by at least two pairs of genes, and was incompletely recessive. Effect of backcross was very significant and that of reciprocal cross was not. Resistance was dominated by nuclear genes, narrow inheritability was comparatively high. The resistance was in keeping with additive-dominance model, and dominance was dominating, and showed a quantitative character.

结果表明：苦瓜对白粉病的抗性受两对以上基因控制，两对主基因抗病相对感病为不完全隐性，回交效应极显著，正反交效应差异不显著，抗病性主要受核基因控制，两对主基因的狭义遗传力较高，符合加性－显性模型，加性效应较大，抗性效应在亲本和F1间存在极显著正相关，表现为数量性状遗传的特点。

The results showed that there are remarkable differences in the content and proportion of water-soluble amino acids in different resistant varieties and the same variety of normal and diseased leaves of Amorphophallus. In this study, the bank of fingerprint chromatogram was established and can be used to analyze the related characteristic peaks and the resistance of Amorphophallus.

结果表明：不同抗病性的品种及同一品种的正常魔芋叶片和病株魔芋叶片中水溶性氨基酸的含量存在显著差别，因而可以以此方法为基础建立指纹图谱库，分析特征峰与魔芋抗病性的关系，为研究魔芋病害防治技术提供新的思路。

In this review, the evidence of association between poly-morphisms of PRNP and resistance or susceptibility to scrapie and its effects on reproduction and performance traits were focused. The aim is to provide theory guidance for sheep breeding resistant to disease.

文章主要介绍了绵羊PRNP遗传多样性与痒病抗病性的关系以及PRNP遗传多样性对繁殖力和其他主要生产性能的影响等方面的研究成果，旨在为绵羊抗病育种研究提供理论参考。

It suggests that there exists a self-defensive mechanism to diseases or a natural disease-resistant mechanism.

提示，机体内存在着自身抗病机制即自然抗病机制。

Cotyledon inoculation method was used to estimate infection rate and to screen resistant and susceptive cultivars of water spinach to white rust (albugo ipomoeae-aquaticae). the results of resistance screening are (1) levels of resistance were not the same among cultivars.

利用子叶感染法，计算感病率来分辨蕹菜品系对於蕹菜白锈菌(white rust， albugo ipomoeae-aquaticae)之抗病能力的实验结果显示：(1)蕹菜对於白锈病的抗病能力随品系而异。

According to the identification, Bacillus subtilis CGMCC No.1982 is a typical Bacillus subtilis. Compared with other Bacillus subtilises, Bacillus subtilis CGMCC No.1982 has broad-spectrum antipathogen fungal activity; the fermentation broth and spore have sound effect in preservation of fresh fruits such as peach, grapes, etc, and also have sound antiviral effect in production of cucumber, tomato and other greenhouse vegetables.
