查询词典 instinct of reproduction

Biological characteristics of the pathogen and the resistance of 13 cultivars of tea plant to tea brown blight were studied by means of natural infection in the field and artificial inoculation in vitro. Resistant cultivars and susceptible cultivars of tea plant were divided. And the resistance mechanism was researched tentatively. The findings are as follows: 1 Some biological characteristics of the pathogenic fungus The experiment result showed: the optimum temperature for the growth of fungus mycelium was from 24 to 27℃, the optimum temperature for sporulation ranged 22 to 30℃. Treated at 54℃ in 10 minutes, the spores didn't germinate. The optimum pH for the growth of the mycelium was 5.1～5.9, the optimum pH for sporulation ranged 5.0～6.0. Light had no much effect on the growth of fungus mycelium, but had much effect on the reproduction of the spore.

首先，研究了茶云纹叶枯病病菌的生物学特性；其次，通过田间抗性调查和室内人工接种鉴定，对 13 个茶树品种进行了抗病性鉴定；第三，在前人研究的基础上，对茶树抗病机理作了更深入的研究，结果发现： 1 病原菌的生物学特性病原菌的分生孢子萌发的最适温度范围为 24～27℃，菌丝生长的最适温度范围为 22～30℃；致死温度为 55℃；菌丝生长的最适 pH 范围为 5.1～5.9，孢子萌发的最适 pH 范围是 5.0～6.0；光照对病菌生长速度及分生孢子萌发影响不大，但对其产孢的影响很大，特别是有光照与无光照处理之间差异显著，光照有利于分生孢子的形成。

The establishment of the technology of silkworm egg long-term storage and its application in commercial production will play an important role in strengthening the planning and controlling ability of silkworm production, in reducing economic losses caused by unbalanced supply and demand of silkworm eggs and the reproduction times of germplasm resources, in preventing race degeneration and in sparing expenditure of silkworm race conservation.

蚕卵长期保存方法的建立及实用化，对增强蚕种生产的计划调控能力，减少蚕种供需失衡造成的巨大经济损失；减少品种资源保存的饲养繁殖代数，防止品种退化，节省保种经费有重要作用，具有很好的推广应用前景。

All things considered, as long as I got to know the above these effects flexo business card printing and membership card making gray balance of factors, and in a real production, all the links in the control to ensure the accuracy of the gray balance reconstruction, so that not only can you make prints get stable and accurate color reproduction, but you can improve business card printing and membership card production quality control and business card printing and membership card making enterprise productivity.

综上所述，只给不妨相识到以上这些感化柔性版制卡和会员卡制息灰不均的不败分，并在本质的不入产洋不差其各个步骤举动公道把持，包管灰不均边现的不确性，这样不仅可以使印品获得安定而又不确的色彩边现，而且还可以提矮制卡和会员卡制息品格度和制卡和会员卡制息企业的不入产效果。

The research results had reference significance for making marker-assisted selection of the reproduction performance in small-tailed Han sheep and other sheep varieties.

结论］该研究结果对小尾寒羊和其他绵羊繁殖性能进行标记辅助选择具有借鉴意义。

Five microsatellite loci (OarHH55, OarJ1A, McM53, BM1329 and BM143) with tight link to FecB gene in small-tailed Han sheep were selected to analyze their polymorphism in the population of small-tailed Han sheep. And its correlation with high reproduction performance of small-tailed Han sheep was preliminarily discussed.

方法］选取与小尾寒羊FecB基因紧密连锁的5个微卫星位点(OarHH55、OarJ1A、McM53、BM1329、BM143)，分析其在小尾寒羊群体中的多态性，并初步探索其与小尾寒羊高繁殖性能的关系。
