亚种

This project was designed to investigate the mechanisms and regulation approaches to poor grain filling and unstableness in the seed setting in TIHR.

本项目旨在探讨两系亚种间杂交稻结实率低而不稳的的生理生化机制与调控途径。

Unstableness in the seed setting and filling is a major constraint in utilizing the heterosis of two-line intersubspecific hybrid rice.

结实率低而不稳是两系亚种间杂交稻杂种优势利用的一个主要障碍。

Simplex because they differ only in a few quantitative characters and seem to be altitudinally vicarious.

simplex 的亚种，因为其区别仅为量的数量特征，和好像是不同海拔的替代种。

In general, European grapes are classed as having originated from the cultivar Vitis vinifera .

一般来说，欧洲葡萄被归类为具有欧亚种葡萄品种源自。

Desert Lesser Whitethroat : minula and halimodendri . Currently, the little studied form margelanica (which may warrant species status) is also contained within this group.

沙白喉林莺： minula 和 halimodendri 亚种，目前研究所知甚少的 margelanica （可能已经被授与到『种』的地位）也包含在这一『种群』里。

The means of three indexes were 55.81%, 0.168 and 0.259 at population level. As a woody, moderately long-lived, obligatedly outcrossing and wind-pollinated species, ssp.

亚种水平的多态位点百分率为89.72％，Nei's基因多样性为0.204，Shannon's多态性信息指数为0.325.14个居群的平均多样性水平为PPB=55.81％，h=0.168，I=0.259。

The plants of the genus Abies are dominant and key species in dark conifer forest in the Northern Hemisphere.

冷杉是北半球阴暗针叶林的优势种和建群种，现全世界共有52种1亚种12变种，在北半球形成南欧、北美和东亚三个分布中心，这三个地区也是冷杉属化石最丰富的地区。

Q .Judged from fossils so far discovered,teeth fossil of Ailurarctos lufengensis can be dated back to 8 million year ago. Ailuropoda microta ,ancient panda which is half the size of today's giant pandas, lived on the planet more than 2million years ago. Ailuropoda milanoleuea daconi ,which belongs to the same species of today's giant pandas made its first appearance 600-700 thousand years ago.

答：从目前的化石记录看，始熊猫已有800万年的历史，距今200多万年前大熊猫小种（Aliuropoda microta，体型约为现今大熊猫一半的古代动物）已经在地球上生活。60~70万年前，与现今大熊猫同种的大熊猫巴氏亚种（ Ailuropoda milanoleueadaconi ，又称巴氏大熊猫）出现。

The results were as follows:(1) Seeds of 80 species or subspecies could be classified into two groups. Group Ⅰ included the seeds of Gramineae, Cyperaceae, Polygonaceae and Amaranthaceae, and Group Ⅱ included the seeds of Compositae, Euphorbiaceae, Brassicaceae and Umbelliferae.(2) Only FTIRs of the seeds of Brassicaceae were clustered together in the dendrogram,while those of the other families all appeared farraginous.(3) Among FTIRs of the 11 groups of the congeneric species,8 groups were clustered with other genus species, and 6 out of 7 groups of conspecific seeds appeared farraginous in the dendrogram.

结果表明：(1)80种草本植物的种子可以分成两类，第1类由禾本科、莎草科、蓼科和苋科植物的种子组成；第2类由菊科、大戟科、十字花科和伞形科植物的种子组成；(2)聚类图上，只有十字花科植物的种子能较好地与其他科的相区别；(3)在11组同属不同种植物中，有8组植物与亲缘关系不同的其他属的植物混在一起；在7组同种不同亚种或品种植物中，仅有1组植物被聚合在一起。
