种子

Abstract; We analyzed patterns of species composition and dominance in the soil seed bank along the

白山南坡土壤种子库物种组成与优势成分的垂直格局。主要研究结果有：(1)从种子数量上看，在不同的海拔段

There is hybrid rice seeds, hybrid corn seed production.

有杂交水稻种子、杂交玉米种子的生产。

If we don't manage to stop their spread in our fields, soon we'll be forced to buy our corn seed because our own won't work anymore?

如果我们不终止它们在我们的田地里的传播，用不了多久我们将被迫使购买玉米种子，因为我们自己的玉米种子无法再繁殖。

It is difficult to meet people that the methods of past identifications.

论文摘要：种子纯度在种子生产中的地位日益提高，以往的形态鉴定等方法难以满足人们的要求。

The status of Seed purity are increased in seed production .It is difficult to meet people that the methods of past identifications.

种子纯度在种子生产中的地位日益提高，以往的形态鉴定等方法难以满足人们的要求。

They are drawn to a wide range of seed types like many North American birds but the mourning dove has a real fondness for corn, millet, safflower, and sunflower seeds.

与很多北美的鸟类一样，哀鸽以各种种子为食，但是它们最喜欢的还是玉米、小米、红花和向日葵种子。

Tomato seeds were firstly immersed in 0.1% mercuric chloride for 10 to 15 min with shaking and then rinsed four or five times with sterile distilled water.

另将番茄种子浸于75%酒精1~2 min，弃酒精后加入足量的0.1%升汞溶液充分振荡10~15 min，再以灭菌水充分漂洗种子4~5次。

Results show that mercuric chloride is an effective chemicals. Optimum treatment by mercuric chloride is 0.128%concentration and 461 second on bacteria-bearing wheat seed.

结果表明：没处理的种子由于发芽时100％长有霉菌，正常幼苗率只有40％，而此批种子经生活力测定结果为生活力64％。

One hundred and thirty four families, 578 genera and 1197 species are recorded in this area. According to the information of historical geology and natural conditions, the composition of seed plant flora and the areal-types of genera were analyzed. The results showed that its origin was rather ancient and its geographical compositions were complicated. There were many species of rare and endangered plants, e.g. Taxus chinensis var. mairei, Bretschneidera sinensis, Emmenopterys henryi, Fokienia hodginsii, Torreya grandis, Phoebe bournei, Ormosia henryi, and so on. Most of these plants had high value in economics and scientific research. According to statistics and analysis of genera in the present flora, 578 genera were divided into 14 areal-types. The ratio of tropical and temperate genera was respectively 48.6% and 49.2%, so its flora was characterized by transitional floristic elements, and in wide connection with the world.

该地区植物种类丰富，共有野生种子植物134科、578属、1197种；根据地史资料和自然条件，通过对种子植物种类的组成和分布区类型的分析，认为该区系起源古老，区系成分复杂；珍稀特有植物多，如南方红豆杉、钟萼木、香果树、福建柏、榧树、闽楠、花榈木等大量古老树种，并且绝大多数具有重要的经济价值和科研价值；区内578属可分为14个类型，热带和温带分布的属分别占48.6%和49.2%，具较明显的南北过渡的现象，与世界各地有广泛的联系。

The effect of free-fall on quality of the seed was studied by dropping six seed lots from four different heights on to cement and galvanized iron floors.

种子自由下落质量检测的效果是这样去衡量的，六个种子一组，从四个不同高度降落到水泥地和电镀铁地板上。

She gently rebuff ed him, but agreed that they could be friends
