种子植物

The most significant variance lay in the 1000-seed-weight,followed by flag leaf length and inflorescence shape and then by distance between flag leaf and inflorescence with least in inflorescence length,plant form,leaf width and seed length.Meanwhile,morphological characteristics of D.glomerata have significant relationships: those with upright and constrictive inflorescences hav...

其中，种子千粒重变异最大；旗叶长度、花序形状次之；穗叶距、花药宽度、旗叶宽度等性状变异中等；而花序长度、株型、叶宽、种子长度变异最小。2鸭茅植物形态学特征间存在明显相关性，花序直立、紧缩的鸭茅，叶片窄长，茎秆粗壮，旗叶较长，雄性生殖器官发育良好，结种性能强；而花序下垂、开展的鸭茅则与之相反。3聚类分析表明，不同野生鸭茅种源可划分为3类，其中花序下垂种源聚于一类；而花序直立的种源分居另两类。4从形态学特征及相关农艺性状分析，花序直立的鸭茅更具开发利用潜力。

This paper deals with some characteristics of water absorbtion and retaining ability of water absorbents of two kinds under different relative humidity environmental conditions.

The results showed that the soil seed banks appeared significantly different in species number,seed density and life form between the different years,the quadrats under grazing and grazing suspension and the different degeneration gradients.

结果显示，土壤种子库物种数、种子密度和植物生活型在年际间、封育与放牧样地间及退化梯度间均有明显差异。

My company and the United States, the Netherlands, Spain, Taiwan, and other horticultural companies and technological exchanges, the form of friendly and cooperative relations will be advanced technology, high-quality products into the Chinese flower, I have now formed a company vanilla plant seeds, flower seeds imported, and seedlings Breeding; potted flowers, bonsai production and sales for the main business; green space conservation, landscape design and construction, supplemented by the operating system.

我公司与美国、荷兰、西班牙、台湾等园艺公司进行技术交流，结成友好合作关系，将先进技术、优质花卉产品带进中国，我公司现形成以香草植物种子、草花种子引进、种苗繁育；盆栽花卉、盆景生产销售为主营业务；绿地养护、园林绿化设计施工为辅的经营体系。

Methuselah beats out the previous oldest-seed record holder, a lotus tree grown from a 1,300-year-old seed in 1995 by Jane Shen-Miller, a botanist at the University of California, Los Angeles, and colleagues.

玛士撒拉击败了之前最老种子的记录保持者——1995年，洛杉矶加州大学的一位植物学家Jane Shen-Miller和她的同事把从一颗1300岁的种子培育成了一株荷叶。

Green fluorescent protein gene was conjugated to the 3 end of the PAP gene in order to screen easily of the transgenic cotton plants. The combined gene was cloned into plant expression vector pBI121 and then transformed. About 5000 seeds of the transgenic cotton were obtained and the some seedlings of the transgenic cotton could give a bright green fluorescence in the dark condition when the cotton seedlings were irradiated with ultraviolet rays. This result reflected that the GFP gene was expressed in the transgenic cotton; dot-blot result also demonstrated that PAP gene was exactly transformed into the cotton. The capacity of the Verticillium dahliae-resistance is being analyzed.

为了便于转基因棉花后代的筛选，在 PAP基因的 3'端融入了绿色荧光蛋白GFP）基因，然后将融合基因克隆在植物表达载体PBI 121上，再进行遗传转化，得转基因棉花种子5000余粒，将种子播种长到于叶展开时，先在黑暗中用紫外灯照射，查找表现绿色荧光的幼苗，然后再用地高辛标记的PAP基因特异性探针对这些棉花进行点杂交，最后发现有8株棉花表现阳性反应，说明PAP基因的确己经转到了棉花的基因组中，其棉花黄萎病的抗性鉴定正在进行之中。

A legume, the Kentucky coffee tree is actually a flowering plant that produces pods containing seeds that are otherwise edible apart from the toxic substance called cystine that it contains, which is poisonous to humans unless the seeds are roasted thoroughly.
