In the fenced plot of site A, the seed percentage of annual and biannual herbs in soil seed bank reserve was very high, and the percentage was even higher in the unfenced plot.

羊草样地围栏内外土壤种子库内的种子均以一、二年生牧草为主，远多于多年生牧草的数量。而围栏外一、二年生牧草在种子库总贮量中所占的比例更高。

First seed, no seed, it doesn't matter, he says, somewhat referring to the fact that he was unseeded for 2005 ESWC - which he won.

一号种子，或是不是种子，都没有什么关系，他说，这里他显然是在暗示在今年的ESWC上他并没有被列入种子，但是却最终夺冠了。

Seedlings from small seeds have higher relative growth rates RGR; gg^(-1d^(-1) than do seedlings from large seeds, under both shaded and unshaded conditions.

在遮荫条件下，幼苗的LAR、SLA、LWR显著增加，但大、小种子幼苗间差异不显著，幼苗的RGR减小，小种子幼苗的减小趋势大于大种子幼苗。

These species represent 13 extant species vegetatively present in the community which and 17 species of earlier, seral species.

种子库中有现存植物种子13种，群落演替前期各阶段产生的种子17种。

Seminal attestation is seminal quality pilot one of important steps, had carried out more than 100 years in Euramerican developed country, it is the seed on current international one of the most successful systems are pursued acceptedly in the industry.

种子认证是种子质量控制的重要手段之一，在欧美发达国家已经推行了一百多年，是当前国际上种子产业中公认的推行最成功的制度之一。

Seed dormancy of M. adenophora was broken by stratifying seeds at alternating temperatures of 30/20℃, 30/15℃, or at a constant temperature of 25℃ for 2mo followed by 5℃ for 3mo, and resulted in rapid germination.

恒春杨梅种子经2个月30/20℃、30/15℃变温层积，或25℃定温层积，接著3涸月5℃低温层积，皆能打破种子的休眠，使种子迅速发芽。

The Hg could inhibit seed germination of Alisma orientale Juzepcz, no seed germination was observed under the Hg solution in this experiment, the reason needs to be studied in the near future. Atrazine along concentration gradient could stimulate seed germination except the low concentration. The seed germination increases with the increasing atrazine content. When the atrazine concentration reaches 50mg/L, the seed germination reaches its peak.

结果表明：重金属汞对泽泻种子有抑制，未能诱发出芽来，其根源还有待于进一步的研究；有机污染物阿特拉津在一定浓度下却促进了泽泻种子的萌发，除了低浓度的T1处理比CK发芽率低以外，随着浓度的增加，发芽率逐渐升高，当阿特拉津浓度为50mg/L时，为泽泻种子发芽率最大值。

The reserves and density of seed banks showed a similar pattern along the altitudinal gradient.

3土壤种子库的种子储量与种子密度的变化规律基本一致。

L Lawfully supervising agricultural ecology protection tasks, organizing ecological and sustainable agriculture tasks; supervising water resources utilization and exploration for fishery, being responsible for the protection of aquicolous and wild animals and plants; supervising utilization and exploration of rural energy resource.

This study investigated the effects of different concentration GA3 on Aralia continentalis Kitagwa seed germination under fluctuating temperature (25℃/5℃), temporal changes in α-amylase activity at 150mgL^(-1) GA3 during stratification were determined.

在变温层积(25℃/5℃)的基础上，采用不同浓度GA3处理长白楤木种子，测定种子发芽率和发芽势，测定150mgL^(-1) GA3处理的种子－α淀粉酶活性的变化。

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

在美国，慢性酒精中毒，肝炎是最常见的。
