植物生物学

Tillering in rice is one of important agronomic trait that determine grain yield. Tillering is also of developmental importance because tiller is special type of branches which is quite different from that of dicot plants. M0C1 gene can control formation of axillary meristematic tissues and tillering bud in rice, and its subsequent outgrowth.

分蘖是水稻等禾谷类作物最重要的农艺性状之一，它直接决定着水稻穗数的多少并进而影响水稻单位面积的产量；分蘖又是单子叶植物一种特殊的分枝现象，具有重要的发育生物学意义。

本文在简要综述前人研究的基础上，深入探讨了化感植物根际生物学问题及攻克途径，以期为深入研究植物化感作用提供依据。

Pingbianensis flowers were ants (Aphaenogaster smythiesii Forel,Formicidea), springtail (Hypogastrura sp., Hypogastruridae, Collembola) and one species of beetles (Anomala corpulenta Motsch, Rutelidae). These pollinators generally have restricted movement capacities and hence promote geitonogamy or mating between individuals in close proximity within populations. The results of out crossing index pollination experiments in our study suggest that T. pingbianensis has an animal-pollinated, mixed selfing and outcrossing breeding systems.

通过对屏边开口箭的开花物候、传粉生物学、交配系统的研究以及对近交衰退的检测，结果显示：屏边开口箭单花花期约15天左右，柱头、花粉活力持续时间较长；传粉昆虫多为蚂蚁、跳虫，偶有小甲虫拜访，缺乏长距离传粉昆虫；杂交指数以及套袋试验的结果表明屏边开口箭为高度自交亲和的混交模式植物，且在幼苗早期并没有表现出明显的近交衰退现象。

From the point of view of geobotany, with the method of correlative factors of growth of plants, a countrywide theoretic ecological division was done for the introduction of Camptotheca acuminata and three kinds of areas of ecological preferent zone, ecological adaptive zone and ecological unadaptable zone were divided. With the theory of synecology, the characteristic on environment, constitution, life form spectrum, diversity, similarity of plots of communities were researched. Applying the method of species association, discrete distribution, indensity index, fractal geometry, etc. to research relations between the species of the communities, space distribution of Camptotheca acuminata, structure of age of Camptotheca acuminata, in different communities. Using the theories of autoecology, distibutons of seeds on land and growth of seedlings in vertical and horizontal directions, biomass of organ of Camptotheca acuminata were analyzed. On the opinions of conservation biology, the external and internal factors impressing Camptotheca acuminata were analyzed to research the mechanism of the endangered species, and with using of CTM Model, the future development direction of Camptotheca acuminata in different communities were forecasted, and. Standing on the position of resources ecology, discussing the regularity of camptothein in Camptotheca acuminata of different sites and seeding of different resources, also the the derive technics of camptothecin.

本文从地植物学的角度，运用植物生长相关因子法，对我国喜树资源的生态适宜区进行了划分，理论上确定了我国的喜树的引种栽培的最适生活区域、生态适宜区域和不适宜生活区域；从群落生态学的角度，对野生喜树所在的典型群落的群落环境、群落组成、群落生活型谱、群落的物种多样性特点、群落样地间相似性进行了研究；从种群生态学的角度，运用种间联结性、离散分布模型、聚集强度指数、分析几何等分析手段，对野生喜树所在典型群落间的种间关系、喜树的空间分布格局、年龄结构等进行了分析；从个体生态学的角度，对不同年龄组的喜树的种子的散落的垂直分布、水平分布、时间分布及种子发芽率和千里重等特点、不同种源的人工喜树苗期特点、喜树的高生长和茎生长特点、喜树的器官生物量特点进行了研究；从保护生物学的角度，对野生喜树的濒危的内部因素和外部因素进行了探讨，并运用CTM模型对不同群落中野生喜树的种群趋势进行了预测；从资源生态学的角度，对我国地理环境下喜树中喜树碱含量的地理分布规律、不同种源的喜树幼苗中喜树碱含量变化规律进行了研究，并对喜树碱的提取工艺进行了探讨。

Taking Aeluropus littorolis that lived in the wetland of Yancheng as the research object, the germplasm resources distribution, habitat, stock and biology characteristics of A. littoralis were studied, so as to provide theoretical basis for using the local halophyte.

以生长于盐城滩涂的獐毛为研究对象，对盐城滩涂獐毛种质资源分布、生境和蕴藏量以及生物学特性进行研究，为更好地开发使用当地盐生植物提供理论基础。

So it has become the hot point of the research in plant heredity and molecular biology.

因此，成为近年来植物遗传育种和分子生物学研究的一大热点。

Conventional forest breeding is constrained by its long reproductive cycle, which includes long juvenile period, and by its complex reproductive characteristics, such as self-incompatibility and a high degree of heterozygosis. Gene transformation has played an important role in woody plant improvement, which can shorten breeding period and breed varieties with high salt tolerance.

随着分子生物学技术的发展，从盐生植物中分离出抗盐基因，导入林木，获得抗盐品种；况且林木由于其较长的幼年期，常规育种有明显的局限性，而通过转基因可以在较短时间内获得高抗盐品种，缩短育种周期，因此开展林木抗盐育种具有重要的意义。

Do the unfamiliar molecular experiment is not my greatest fear, few chance to hobnob with the nature is.

我不太怕做自己非常不熟悉的分子生物学实验，我怕的是没有机会去认识植物和亲近他们。

Originally designed to homogenize plant tissue for nucleic acid and protein isolations, it has since found use in all areas of biological research that require high throughput homogenization.

最初设计用于均质核酸和蛋白质的植物组织，目前已应用在所有需要高吞量同质的生物学研究中。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
