对抗病

The resistance of strawberry was observed at each phase of the invasion after formation of the appressorium.

而草莓不同品种对白粉菌的抗性表现在附着胞产生后的各侵染阶段，随品种抗病性增强，病菌侵入率降低，吸器数目减少，菌丝扩展缓慢，分生孢子数目减少。

The fungicidal activities and disease resistance of short peptide LD-1 against Botrytis cinerea were tested in this paper.

本文以番茄灰霉病为供试菌株，研究了短肽LD-1对番茄灰霉病的抑制作用及其抗病性。

With the Shuangyi and Gongrong as rootstock and large white articles and green bitter gourd as cion, the effect of engraft with different rootstocks on the quality and disease resistance were studied.

方法］以双依、共荣为砧木，以大白苦瓜和绿苦瓜为接穗，研究不同砧木嫁接对苦瓜品质、抗病性的影响。

In this study the clubroot resistant CR DH line, susceptible inbred line 94SK of Chinese cabbage, the resistant and susceptible DNA bulks constructed from F2 individuals of CR DH line and 94SK were used to select the adaptive AFLP primer combination. AFLP analysis was performed with 256 Pst Ⅰ/Mse Ⅰ primer combinations.

为了筛选出大白菜适宜的AFLP引物组合，研究以抗根肿病大白菜双单倍体CR Shinki、感病自交系94SK及其后代F2构成的纯合抗病和纯合感病DNA混合池为材料，利用256对Pst Ⅰ/Mse Ⅰ引物组合进行了AFLP分析。

By bulked segregant analysisin F2progenies of 95-5383×HB1,we have identified one codominant RAPD marker〓 closely linked to SMV resistance gene.

利用BSA法对95-5383×HB1的F2代进行鉴定，筛选出与SMV抗病基因紧密连锁的共显性RAPD标记〓。

The experiment were designed into three experiments and investigate the effect of mannanoligosccharide, Chinese herbal Medicine, Microecologics on disease-resistant,the activity of digestant enzyme, growth performance of broilers.

本研究分为三个试验，分别研究甘露寡糖、中药和微生态制剂对肉鸡抗病性、消化酶活性和生产性能的影响。

And soon they become disincline to anything arround them, meanwhile, their immunity against disease is weaken, then kinds of diseases will come to visit.

很快他们对周围事物不感兴趣，同时，抗病能力下降，种种疾病接踵而至。

Furthermore, 13 Italian durum and 20 bread wheat cultivars and 11 Chinese wheat cultivars were also tested at seedling stage with 10 Italian isolates of pathogen.

在田间成株抗性监测中，12.2％和58.9%的硬粒小麦品种和面包小麦品种分别表现抗病或中抗；在苗期抗性鉴定中，参试的很多中国品种对大部分意大利菌株表现免疫、近免疫或高抗。

The protein encoded by RBB1 contained two conserve domain ATP-synt-DE-N and AtpC from 3 to 83 and from 1 to 133. All above showed that the full length cDNA RBB1 encoded ATP synthase CF1 epsilon chain protein The plant resistant mechanism is very sophisticated and one of the mainly responses is the metabolic change.

植物的抗病机理非常复杂，其主要反应之一就是代谢上的变化，例如，在利用cDNA微阵列对水稻抗稻瘟病近等基因系的分析中，检测到了很多与光合作用和糖代谢功能有关的差异表达片段；在小麦中也筛选到一个植物中ATP酶具有高度同源性的cDNA序列可能与小麦抗白粉病相关。

The results indicated that the types and contents of amino acids examined were different in these root exudates.

研究结果表明：感病品种根系分泌物能够刺激胞囊的孵化，而抗病品种根系分泌物对胞囊的孵化未表现明显刺激作用。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
