发育能力

On the base of review the research development in tissue culture and genetic transformation, Comparative analyses were made on the callus induction and embryogenetic abilities of anther and non-pollinated ovules of rubber tree. Fluorescence detection was implemented with the different in vitro material of Hevea brasiliensis.

本研究在综述了橡胶树组织培养及遗传转化研究进展的基础上，系统地比较了橡胶花药和未授粉胚珠愈伤组织诱导及体细胞胚胎发生能力，对橡胶树不同离体组织进行荧光背景检测，将在植物胚胎发育时期起重要作用的BBM基因导入橡胶树，对电激法转化游离小孢子细胞以及农杆菌介导花药愈伤组织进行初步探索。

Frederica Perera, DrPH, director of the Columbia Center for Children's Enironmental Health noted that, By identifying enironmental exposures that adersely effect fetal deelopment and also affect children's ability to learn, the research proides new opportunities for preention.

哥伦比亚儿童环境健康中心的主管Frederica Perera博士表示，通过证明环境暴露对胎儿发育和对儿童学习能力的副作用，这项研究为预防提供了新的可能性。

Early intervention was used to educate and train the hypophrenia children initially, but in these years, it has been gradually utilized in the clinical therapy of HIE because the happeness of sequels of the moderate and severe HIE was not decreased well even when active drug treatment has been used in neonatal period.

早期干预就是根据小儿神经生理与神经发育的原理和规律，利用各种方式刺激运动及感知通路上的神经元，调节其兴奋性，以获得正确的感知力及运动控制能力的一类早期预防康复治疗技术。

In contrast, the ontogeny of call usage and comprehension is stongly influenced by experience in several nonhuman primates, and possibly in some birds (Cheney and Seyfarth 1990; Hauser 1996; Marler 1991), with benefits accruing to individuals that can learn to use call types and subtypes in new ways.

相反，对一些非人类灵长类来说，合体发育过程中鸣叫的使用和理解能力受经验的强烈影响，尤其是对一些鸟类来说（切尼和塞法特1990；豪瑟1996年，马勒1991年），个体积累的利益是可以学习使用呼叫类型和亚型。

The results showed that the compound antiseptic-antibiotics which were composed with sorbic acid, BCM and doxycycline, not only improved the antiseptic ability of the artificial diet, but treated the septicaemia and muscardine very well with the effect of more than 90 percent.

作者以小蚕生长发育及人工饲料保质期为指标，对多种防腐剂、防霉剂及抗菌素在人工饲料中添加效果进行了比较，筛选出由山梨酸、BCM 及强力霉素组成的复合型防腐抗菌剂，不仅明显提高了人工饲料的防腐能力，而且对蚕的败血症和僵病的治疗效果均达到90％以上，具有防腐和防病的双重作用。

Lipid peroxidation would cause the deficiency of myelinogenesis, Dysfunction of synaptic conduction and developmental anomaly of nerve cell if the deficiency of completely.

当硒缺乏时，硒蛋白活性降低，清除H2O2能力减弱，脂质过氧化导致髓鞘形成不良，突触传导障碍，神经元发育异常，造成严重的脑功能紊乱。

The development cycle in the silkworm accorded with the feature of Genus Nosema.

b。有差异；黑条灰灯蛾微孢子虫的发育周期符合Nosema属的特征；对家蚕有中等程度的感染能力，经卵传染频率较低。

The Vg-negative reaction of the triploid female rainbow trout could not provide full evidence for the impossibility of liver to synthesize Vg. That Vg was not synthesized resulted from insufficient estradiol due to the retardation of ovaries development, the un-differentiation of follicular cells and the lost interaction of germ cell and somatic cells. It could be concluded from yolk genesis that the shortage of female triploid rainbow trout's Vg resulted from the abortive ooecium, but did not result in sterility.

由于三倍体雌性虹鳟卵巢发育受阻，无滤泡细胞分化，生殖细胞与体细胞的互作缺失，不能分泌足量的17β-E2以诱导Vg的合成，因而肝脏的Vg阴性并不能说明肝脏不具备合成Vg的能力，从卵黄发生的角度分析，卵黄蛋白原的缺乏不是导致三倍体虹鳟雌性不育的原因，而是其卵泡败育的结果。

Important pediatric issues, including bodysize, pubertal development, and ability to tolerate nil peros status, must be considered.

儿科方面包括身体大小、青春期发育及耐受禁食的能力都是必须考虑的重要问题。

Polyphenols and antioxidant capacity in different organs of Muscat Hamburg in the whole growth periods, and the effects of seedlessness treatment on polyphenols and antioxidant capacity of Muscat Hamburg were studied. The main results are as follows: 1. From the beginning of blooming period to the ripening period of Muscat Hamburg, the content of polyphenols in different organs decreased at first, and then increased with the development of the grape berry.

本文以玫瑰香葡萄为材料，研究了整个生长发育期内葡萄各个器官及无核处理葡萄的酚类物质及抗氧化能力变化，主要结果如下： 1从玫瑰香葡萄始花期开始，至浆果成熟期止，随着果实的发育，葡萄内各个器官的酚类物质含量呈现先下降后上升的趋势。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
