胁迫的

The ability of maintaining turgor pressure, osmotic adjustment,capable of preserving and endurance of water separation capability were increased under elevated CO_2 concentrations,whereas the resistance of water separation capability decreased.Theε~max increased in normal water condition of Acer truncatum under 720μmol·mol~(-1)CO_2,and cytoderm more hardness and less elasticity.But in circle 3,ε~ decreased in light and middle drought conditions and increased in serious drought condition.(5) The branch 0,branch 1 and branch 2 of hydraulic conductivity of 7 trees increased along elevated CO_2 concentration.

随着CO_2浓度的增加，RWC~0/RWC_s下降，Ψ~0π和Ψ~(100)π在循环1时先增加后下降，一直持续到循环3，高CO_2浓度下元宝枫维持膨压的能力增强，渗透调节和自身保护能力，以及忍耐脱水能力虽然增加，但是抗脱水能力却减弱了，不能同时兼得。720μmol·mol~(-1)CO_2元宝枫ε~在水分条件较好时增加，细胞壁较坚硬，弹性小，但是到循环3时，ε~在轻度干旱和中度干旱时下降，到后期水分严重胁迫时却升高。

The result indicated, In the MS culture medium, and the damagement increased with Pb(superscript 2+) concentrition, when Pb(superscript 2+) concentration was up to 1000μmol/L, the callus was geatly damaged and its character is small, hard, skin drying; Organic acid of suitable concentration was able to improve the induction and growth of rice callus under the Pb(superscript 2+) stress, i.e. ascorbic acid, critic acid and oxalic acid The effect was the best which added 750 mol/L citric acid in MS culture medium, the callus was fresh, light yellow, loose, the surface moist. and survival was as higher as controlled treatment.

而添加不同有机酸（抗坏血酸、柠檬酸和草酸）均可明显改善Pb(上标 2+)胁迫下愈伤组织的生长，尤以750μmol/L柠檬酸对Pb(上标 2+)毒害的缓解效果最佳，其愈伤组织块颜色浅黄，表面湿润，愈伤组织成活率高，与对照愈伤组形态较接近。

And the diurnal variation of physiological characteristics of photosynthesis of Magnolia denudate under heavy metals stress were studied with the Li-6400 portable photosynthetic system.

为了解锑矿区土壤复合重金属污染对白玉兰光合生理特性的影响，分重度污染、轻度污染和无污染土壤栽培白玉兰苗木进行盆栽试验，并采用LI－6400光合测定系统对重金属胁迫处理的白玉兰进行了光合生理特性日变化研究。

The results show that there existlaminal paraheliotropic movement and diaheliotropic movement under light stress,whichadjusts absorption of light energy.

结果表明：自然强光胁迫时，无性系通过叶角的&避光运动&调节对光能的摄取量。

Three Elsholtzia splendens populations,one from an uncontaminated site and the other from two Cu mine sites,were studied in hydroponic experiments for the photosynthesis and transpiration under Cu treatment.

通过水培实验，对种子分别来自湖北省铜绿山、赤马山铜矿区和红安非矿区的海州香薷种群在铜胁迫下的光合作用和蒸腾作用进行了比较研究。

In order to study the pyrethroids pesticides stress on the physiological and biochemical process of vegetables, effects of different concentrions of fenvalerate stress (20% emulsifiable concentrate, recommended dose: 1500 times dilution; double dose: 750 times dilution) on the activities of antioxidant enzymes, and contents of malondiadehyde in pakchoi were investigated under the open-field condition.

为探讨菊酯类农药胁迫对蔬菜生理生化过程的影响，以小白菜为研究对象，采用大田试验研究了不同浓度氰戊菊酯（20%乳油，推荐用量：稀释1500倍；加倍用量：稀释750倍）对小白菜抗氧化酶活性及丙二醛含量的影响。

In our experiment, we treated leaves of Vicia faba in vitro with solution of different pH value to research the activity change of defense enzyme.

利用不同pH值的酸碱溶液处理蚕豆或者离体蚕豆叶片，研究酸碱胁迫下蚕豆叶片保护酶活性的变化。

I have thought of going to work, but I am unwilling to admit that I do not know how to use my freedom and have to embrace the flunkydom of a job because I have no resources - in a word, no character.

我曾考虑去工作，但是我不愿承认我不知道如何获取自由，如何融和工作的胁迫，总之，我没有从分的准备，没有这种品质。

The increase in the ratio of root to shoot was more in Spiraea pubescens and Lespedeza bicolor than in Quercus liaotungensis and Fraxinus, which shows that biomass allocation preferred to roots not to stems or leaves under drought conditions.
