种子

The sea coconut tree, which is also known as king palm, grows only in Seychelles in Africa.

世界上最大最重的种子，一粒种子重量可达15公斤。

Both of them, to be codominant markers, can identify false hybrids not only from selfed seeds of male and female but also from foreign pollen and mechnical contamination.

两引物均能在父母本中扩出特异带，为共显性标一记，不仅能够鉴别杂交种中混杂的母本自交的种子和父本的种子，还可鉴别部分由于外来花粉或机械混杂等造成的假杂种。

Then we hypothesize that mesenchyma stem cells from DAC are heterology,which have the potential ability to regenerate root/periodontal complex structures as a new kind of seed cells. Therefore, this study focuses on characteristics of the mesenchyma stem cells at tooth root developing stage and the evaluation of the possibility of being seeds cells.

因此，本研究拟对牙根发育期相关间充质干细胞的生物学特性进行研究，探讨其作为种子细胞在牙根/牙周组织工程中应用的可行性，以期为组织工程化牙根/牙周组织构建优选新的种子细胞。

When we give up all claim to a knowledge of the final end, we shall clearly perceive that just as we cannot invent any flower or seed more truly appropriate to a plant than those it produces, so we cannot imagine any two persons, with all their past in such complete congruity down to the smallest details, with the part they were destined to play.

放弃对最终目的的探求，我们便会清楚地看到，一种植物有一种植物的花朵和种子，我们无法去空想更适合于这种植物的其他花朵和种子。同样，我们也无法想象其他两个有各自经历的人能比拿破仑和亚历山大更合适地、更细致地和更彻底地完成他们天赋的使命。

All the contents of Extractable heavy metal like Pb, Cu, Zn and Cd in limestone slagged wasteland are higher than those in contrapositive soil nearby. The slag filtrate has no effect on seed germination rate of Mung beans, Broad beans and Corns but restrains their germination vigor and protraction of hypocotyls with root restraint rate exceeding 30-50%; While it has an apparent effect on germination rate and germination vigor of sensitive seeds like Beans with P=0.05. Simulate to plant the 4 different seeds in pot for a month, Test groups have a lower data in total leaf area, plant height and weight but a much higher content of protective materials like PRO and MDA in biochemical mensuration experiment compared with CK group.

石灰炉渣废弃地中Pb、Cu、Zn、Cd重金属有效态含量均高于临近对照土壤，其炉渣淋出液对绿豆、蚕豆、玉米3种植物种子发芽率无影响，但均抑制其发芽势和下胚轴伸长，根长抑制率达30%~50%以上，对敏感种子黄豆的发芽率、发芽势（4d）影响明显，摸拟盆栽一个月苗期，4种植物试验组在总叶面积、株高、生物量方面均低于对照组；生理生化测定，4种植物其体内抗逆性保护物质脯氨酸和膜过氧化产物丙二醛含量试验组均高于对照组。

In previous study,the ability of plant resist-drought almost focuses on plant foot,corm and leaf,except seed, especially,large number kinds of plant species is not report.

以往的植物抗旱性研究，多集中在植物成株后的根、茎、叶组织等方面，而对种子的抗旱性研究较少，特别是对批量旱生植物种子，在各种水分条件下的响应方式的研究未见报道。

Key words: paddy field; perennial weed; seed bank;tuber;corm

同时阐述了种子和块茎的寿命，以及免耕和水旱轮作对稻田多年生杂草种子库的影响，并提出了控制措施。

Having been regenerated not of corruptible seed but of incorruptible, through the living and abiding word of God.

你们蒙了重生，不是由于能坏的种子，乃是由于不能坏的种子，是藉着神活而常存的话。

Using male sterile make crossbreed is the best way of hybrid seed production,and have achieved some success,but in seed yield and production of three-line there are still many problems and shortcomings,in particular, In China,the male sterile technology is still in the preliminary study stage.

采用雄性不育系生产杂交种是种子生产中最好的方法，一直受到苜蓿育种工作者的重视，并取得了一些成绩，但在种子产量和三系配套生产中还存在很多问题和不足，特别在我国，不育系杂交制种技术还处于初步研究阶段。

Then he spoke to the birds, and they carried seeds of every kind of flower and strewed them far and wide, and soon the prairie bloomed with crocuses and roses and buffalo beans and the yellow crowfoot and the wild sunflowers and the red lilies all summer long.

"你的花在那里？"，原野回答说："主人，我没有种子。"。于是主人吩咐禽鸟把各类花的种子带来，四处播种。不久原野上就开出了番红玫瑰，水豆花，毛莨花，向日葵，红今兰，以及一些耐热的夏季花卉。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
