肥沃

The response may change the fate of the turions in the second year,and affect the maintenance of the populations.

在野外池塘中，利用3种不同营养状况的底质研究底质营养盐对菹草生长及养分分配的影响，结果表明：沉水植物菹草面对底质营养盐的胁迫出现了急性的生理生化反应，在生长初期叶片总的可溶性糖含量在肥沃的底质上高于贫营养底质上；根、茎、叶和石芽各构件都具有异速生长现象，并且表现规律不一样；菹草的根冠比随底质营养盐的不同而变化；随着营养条件对菹草生长胁迫加重，根、冠的异速生长愈明显，同时石芽的N∶P和C∶N比率显著受底质营养盐的影响，而菹草叶片和茎N∶P和C∶N比率不受底质肥力的影响，这些响应将改变石芽第2年的命运和影响种群的维持；在胁迫生境下，菹草首先分配资源到无性繁殖体--石芽上以便维持种群的延续，以回避策略应对底质营养盐胁迫。

They fly,float,hitchhike--and even explode,But the many clever ways seeds get aroud make sense:after all,a plant's life depends on tinding fertile ground in which to grow.

他们飞翔、漂浮、冬眠－－并且甚至爆炸，但是许多聪明的传播种子的方式更有意义：毕竟，一个植物的生命依靠寻找肥沃的土地并生长。

The middle of the logo is a horse, symbolizing the valuable stallions bred in Stuttgart, while marked in the upper left and lower right corner is a pattern of staghorns which means that Stuttgart is a good place for hunting. At the top right and bottom left are yellow stripes on behalf of the ripe wheat, symbolizing a bumper grain harvest , black stripes for fertile land, and red, which symbolizes people's wisdom and love of nature.

车标的中间是一匹骏马，代表斯图加特市盛产的一种名贵种马；在车标左上方和右下方是鹿角的图案，表示斯图加特曾是狩猎的好地方；在车标右上方和左下方的黄色条纹代表成熟了的麦子，喻示五谷丰登，黑色代表肥沃的土地，红色象征人们的智慧和对大自然的钟爱。

The purpose of the research was to obtain bacterial polyhydroxyalkanoic acids producers with good characters. With bottom sludge from Donghu Lake, bum soil from hillside, fertile vegetable soil and oil-soaked soil as initial samples, the bacterial strains with ability of synthesizing PHAs were screened not through enriching, isolation and purification, staining with Sudan black B and qualitative and quantitative analyses by infrared spectroscopy and gas chromatography. The results of staining with Sudan black B showed that there were 3 strains with ability of synthesizing PHAs among the 12 isolated strains and their numbers were Zj-5, Zj-8 and Zj-9 resp. All the 3 strains took on adsorption peaks at the points near 1741 cm^(-1) and the infrared spectrums of the strains Zj-8 and Zj-9 were similar.

［目的］获取性状优良的聚羟基烷酸合成菌［方法］以东湖底混、山坡裸地土、肥沃菜园土和油脂浸润土为初始样品，经富集、分离纯化、苏丹黑B染色、红外光谱及气相色谱定性定量分析筛选出具PHAs合成能力的细菌菌株［结果］苏丹黑B染色结果表明，在分离出的12株细菌中有3株细菌具有PHAs合成能力，其编号分别是Zj-5、Zj-8和Zj-9.3株细菌均在174cm^(-1)附近呈现吸收峰，菌株Zj-8和Zj-9的红外谱图相似。

Method］ With bottom sludge from Donghu Lake, bare soil from hillside, fertile vegetable soil and oil-soaked soil as initial samples, the bacterial strains with ability of synthesizing PHAs were screened out through enriching, isolation and purification, staining with Sudan black B and qualitative and quantitative analyses by infrared spectroscopy and gas chromatography.
