结果表明：适当浓度的水杨酸能够降低盐胁迫下草莓叶片质膜相对透性和过氧化程度，提高叶绿素含量和抗氧化酶活性，从而缓解NaCl对草莓的伤害，改善草莓的生长状况。

In leaves,the concentration of Cd and Cu been up to 168.6μg·g~(-1) and 30.1μg·g~(-1),while in roots, they have been to 610.9μg·g~(-1) and 384.6μg·g~(-1).In these concentration compages,the leaves could accumulate Cd at a high rate,Cd50mg·g~(-1) Cu50 mg·g~(-1),Cd80mg·g~(-1) Cu30 mg·g~(-1),Cd80mg·g~(-1) Cu50 mg·g~(-1).At the concentration of Cd50mg·g~(-1) Cu50 mg·g~(-1), Iris pseudacorus L. could accumulate Cd and Cu at a high rate:inleaves,Cd82.908μg·g~(-1), Cu30.722μg·g~(-1),in roots, Cd266.181μg·g~(-1), Cu395.83μg·g~(-1),and at this concentration the plant could grow well, the dry weight of leaves and roots of it were 64.3% and 81.1% of the concentration compage Cd0mg·g~(-1 Cu50 mg·g~(-1)s.

研究表明，①黄菖蒲对Cd、Cu均有较强的吸收积累能力，其中对Cd的吸收积累能力相对大于Cu：地上部Cd、Cu含量最高分别达168.6μg·g~(-1)和30.1μg·g~(-1)，根部Cd、Cu含量最高分别达610.9μg·g~(-1)和384.6μg·g~(-1)；黄菖蒲地上部分Cd积累量均随处理浓度的升高而增加，特别在处理Cd50mg·g~(-1) Cu50mg·g~(-1)组合胁迫下，黄菖蒲对Cd、Cu的积累量为：叶的Cd含量为82.908μg·g~(-1)，Cu为30.722μg·g~(-1)；根的Cd含量为266.181μg·g~(-1)，Cu395.83μg·g~(-1)，且生长良好，叶和根的干重分别为处理Cd0mg·g~(-1) Cu50 mg·g~(-1)的64.3％和81.1％。

The levels of drought tolerance and nucleotide polymorphism at CBF4 locus in a worldwide sample of 17 core accessions of Arabidopsis thaliana were examined. The results showed that different accessions had quite difference in adaptation to drought stress.

以生长于不同生态气候条件下的17个拟南芥核心生态型为材料，分析了它们的相对抗旱性和抗旱转录因子CBF4 基因的单核苷酸多态性。

The traits correlation analysis indicates: The table mould correlation of stem volume and height ,DBH ,crown width , has achieved the utmost point level of significance , The straightness with other traits correlation indicates that we can get some improvements when we select other traits.

发现它们的家系和单株遗传力大小关系：树高＞材积＞胸径＞冠幅＞高径比＞冠径比＞通直度；即树高生长相对其他性状具有较强的遗传力。

It was obvious that the adaptability to lower temperature and critical low temperature are two relative independent character.

两种逆境对黄瓜生长的影响结果不同，黄瓜对两种逆境的耐受性是两个相对独立的遗传性状。

Based on the information taken from the subcompartmental records a comparison between the actual and normal forests was made and a new point of view was proposed in the article: in the case of cultivating timber-forest which is different in cutover age, age class and growing speed within the range of the whole forest station, the forest age class distribution showing the opposite shape of "J" is of more benefit to keeping the relative stability of all the age class area than the age class distribution of th...

本文在统计森林资源小班档案卡片有关资料的基础上，把现实林分与法正林相比较，用法正林学说来指导全场森林的调查。并提出了一个新的观点：在整个经营单位内，培育不同生长速度，不同主伐年龄，龄级期不同的用材树种，森林的龄级结构呈反"J"形分布此法正分布更有利于维持各龄级面积的相对稳定，并且，年伐量的波动不大，有利于森林的永续利用。

This transformation for the D'Arcy Thomson on growth and morphology and Julian Huxley discussion on the relative growth is essential.

关于生长与形态和 Julian Huxley 关于相对增长问题的讨论是至关重要的。

To transplant Elodea nuttallii,Potamogeton crispu in winter when water level is lower and its transparence is higher than other season is an effective way to establish pioneer submersed plant community.

利用冬季水位低、透明度相对高的时机种植伊乐藻、菹草等这些适合冬春季生长的沉水植物是建立沉水植物先锋群落的一个有效途径。

Word fluency was not affected by folic acid supplementation, perhaps not surprisingly, because encyclopaedic memory is a component of crystallised intelligence that stays relatiely intact as one grows older.

文字流利度并没有被叶酸补体所影响，也许只是不明显，因为百科全书式的记忆是明确智力（它作为一个生长顺序而相对完整）的一个组成部分。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
