胁迫地

Using 192 lines from BC2F2 backcross population and their equivalent progeny BC2F3, fine mapping of SKC1 was performed.

SKC1是一个控制盐胁迫下水稻地上部K+浓度的主效QTL，它可以解释40.1%的K+浓度表型变异。

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％。

Compensatory effects were also found in the growth of both shoots and roots of rice.

水稻地上和地下部生长对轻度胁迫也存在明显的补偿效应。

Ascorbate is concomitantly oxidized to monodehydroascorbate. Some monodehydroascorbate radicals are re-reduced in a reaction catalyzed by monodehy- droascorbate reductase, but the remainder undergoes spontaneous dismutation to ascorbate and dehydroascorbate.

在抵抗氧化胁迫的反应中，抗坏血酸自身被氧化为单脱氢抗坏血酸，一部分单脱氢抗坏血酸在单脱氢抗坏血酸还原酶的催化作用下还原为抗坏血酸，另一部分单脱氢抗坏血酸的在歧化作用下被不成比例地还原为抗坏血酸或氧化为脱氢抗坏血酸。

The products of these defen-sive genes could act on the herbivore in...

植物的各种防御信号途径之间既存在拮抗作用又有协同作用，共同组成了一个复杂的防御体系，在一定程度上有效地抵御各种生物胁迫。

He sets out to prove that to punish the mad, the infant child or those who break the law unintentionally or under duress or even under 'necessity' must be inefficacious; but all that he proves is the quite different proposition that the threat of punishment will be ineffective so far as the class of persons who suffer from these conditions is concerned.

他试图证明惩罚疯子、法定未成年人或在受到胁迫的情况下无意识地乃至在"紧急避难"的情况下触犯法律的人[MSOffice1] ，必定毫无效果。但是，其所证明的却是这样一个完全不同的命题，即惩罚的威吓对那些处于此类状况下的人不起作用。

Interviews typically begin with mild, nonthreatening questions concerning demographic matters.

关于人口统计学的物质用温和又非胁迫的疑问典型地接见开始。

Meanwhile, ions and nitrogen accumulation in shoot had significantly positive correlations with those root morphologic characteristics.

高盐胁迫下增加氮营养，显著增加了地上部Na+、NO3-、有机氮的含量和硝酸还原酶的活性；降低了Cl-和K+的含量。

The results showed that:Under NaCl stress,the reductions in the shoot and root dry weight, leaf area,stem diameter of grafted plant were lower than those of ungrafted plants.The Na~+ content,Na~+/K~+ ratio,Na~+/Ca~(2+) ratio in the leaf and scion stem of grafted plants were lower whereas those of in the rootstock stem ad root were higher than in ungrafted plants. The K~+ contents,soluble sugar contents,shoot water contents,SOD,POD,CAT,APX activity,the stability of AsA/DHA,Photosynthetic rate,transpiration rate and stomatal conductance were higher,whereas the MDA contents in the leaf of grafted plants were lower than that in ungrafted plants.The reductions in leaf area and stem diameter of grafted \'Jinchun No.2\' plants were more severe than those of grafted \'Zaoduojia\' ones.

结果表明，盐胁迫下，嫁接苗地上部和根干重、叶面积、茎粗降低的程度显著低于自根苗；嫁接苗叶片和接穗茎中Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著低于自根苗，而砧木茎和根中的Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著高于自根苗；嫁接苗叶片中K~+含量、可溶性糖含量、地上部含水量、SOD、POD、CAT、APX活性、AsA/DHA的稳定性、光合速率、蒸腾速率、气孔导度显著高于自根苗，MDA含量显著低于自根苗。

The results showed that:The reductions in the shoot and root dry weights, leaf area,stern diameter of grafted plants were lower than those of ungrafted plants under the same NaCl stress.Na~+,MDA,H_2O_2 contents,O_2~- producing rate,Na~+/K~+ ratio, Na~+/Ca~(2+) ratio were lower,whereas K~+,solube sugar,shoot water content,SOD,POD, CAT,APX activity,the stability of AsA/DHA,Photosynthetic rate,transpiration rate and stomatal conductance in the leaf of grafted plants were higher than those of ungrafted plants at the same NaCl stress.Intercellular CO_2 concentration of grafted plants decreased whereas that of ungrafted plants increased significantly under salt stress.

结果表明，盐胁迫下，嫁接苗地上部和根干重、叶面积、茎粗受抑制的程度显著低于自根苗；嫁接苗叶片中Na~+、MDA、H_2O_2含量、超氧阴离子产生速率、Na~+/K~+和Na~+/Ca~(2+)比值显著低于自根苗，而叶片中K~+含量、可溶性糖含量、地上部含水量、SOD、POD、CAT、APX活性、AsA/DHA的稳定性、光合速率、蒸腾速率、气孔导度显著高于自根苗；嫁接苗的胞间CO_2浓度显著下降，自根苗的则显著上升。
