胁迫的

At the same time, the content of the praline turned to be 118.85%, 128.28%, and 183.61% of CK, respectively.

强度试验显示，随酸雨胁迫强度增加，可溶性蛋白含量经历了升降转变过程，其中pH值为4.5、3.0和2.5时，蛋白质含量是CK（对照，pH 7.0）的147.98%、111.50%和73.69%；但脯氨酸含量持续上升，pH值为4.5、3.0和2.5时，脯氨酸含量是CK的118.85%、128.28%和183.61%。

The increment of praline content and SOD activity in the seedlings raised in organic soil base was more than that in the seedlings raised in nutritional soil base under moderate drought stress.

在中度干旱胁迫条件下，有机基质所育秧苗水稻叶片的脯氨酸含量和SOD活性增加的幅度大于营养土所育秧苗。

The content of free proline of three treatment increased at the beginning, then decreased and went up again.

水杨酸、热锻炼和对照的脯氨酸含量在胁迫过程中均表现先升高后降低，再升高的变化趋势。

Proline is accumulated in higher plants in response to different environmental stresses.

中文摘要环境胁迫诱导的脯氨酸积累是植物一种非常显著的代谢适应机制。

The above results indicate that exogenous Putrescine could improve osmotic adjustment ability of winter wheat seedling leaves under drought stress and increase drought tolerance of plant.

这说明外源腐胺能改善冬小麦幼苗叶片干旱胁迫下的渗透调节能力，从而增强植株的耐旱性。

The scion and radicle had different response to the salts, and the salt concentrations had more influence on the radicle.

幼根和幼芽对不同种类盐胁迫表现出不同的反应，盐浓度对根的影响较大。

If it is not severe, such as at 50℃ for 1 minute, the relative content of the inactive PS Ⅱ center decreases to 70% and further to about half of its control during the following readaptation to room temperature in 60 minutes. The reason for this unusual phenomenon is not clear.

发现在高温胁迫不太严重时（如50℃1分钟），无活性PS Ⅱ中心的含量降至对照的70％，在随后室温60分钟恢复过程中继续降为50％。

The transformation of the active and inactive PS Ⅱ centers in the readaptation period under room temperaturre after heat stress is studied.

高温胁迫后的室温恢复期中有活性和无活性PS Ⅱ中心相互转化的研究。

Under drought stress,content of soluble protein increased first and thendecreased,and content of soluble saccharide increased continuously.

在干旱胁迫下，可溶性蛋白质含量呈现先升后降的变化特点，而可溶性糖含量则持续上升，因而推测可溶性糖在逆境条件下，起抗脱水作用的时间可能比蛋白质要长一些。

Salt absorption, transpiration induced water uptake and the radial reflection coefficient of the root system of arrowleaf saltbush were measured in order to analyze ultrafiltrational characteristics of its root system in relation to salt tolerance of the plant.

对耐盐蔬菜三角叶滨藜在盐胁迫下的蒸腾吸水量、Na吸收和根系径向反射系数进行了测定，分析其根系超滤特性与植物耐盐性的关系。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
