渗透调节

These facts indicated that Vicia faba L.had certain osmoregulation ability.However,osmoregulation ability had certain limitation.

这些指标均与土壤含水量呈负相关，表明蚕豆具有一定的渗透调节能力。

An experiment was conducted to investigate the effects of salt stress on biomass, activated oxygen metabolism and osmoregulation content of split-root Leymus chinensis seedlings in an auto-rain-shelter greenhouse.

在自动控制的遮雨棚中，研究了200 mmol·L-1NaCl胁迫对不同分根处理羊草幼苗生物量、活性氧代谢以及渗透调节物质含量的影响。

The results also suggested that a better capacity for osmoregulation in S. przewalskii might account for its greater capacity for freezing tolerance than S. chinensis .

祁连圆柏的相对含水量和自由水含量均低于圆柏，3种有机渗透调节物含量均高于圆柏，表明祁连圆柏在抗冷冻性诱导中具有更广泛的适应性策略。

Both proline content and K+ content in leaf at four different ABAconcentrations increased more than that in control plant, exogenous ABA promotedproline generation and K+ accumulation in leaf resulting in osmoregulation.

四种ABA浓度下叶片中的脯氨酸和K+含量均比对照明显升高，外源ABA能够促进叶片中脯氨酸形成和K+的积累，导致渗透调节的发生。

Only under the sudden strike of extremely low temperature, such as -10癈,-20 癈, the cell membrane could be seriously damaged by lipid peroxidation.The variations in the content of main metabolic osmoregulatory substances, such as soluble sugars, protein and free proline were all tightly related to the cold resistance of podocarpus fleuryi Hickel seedlings.

只有极低温，如10oC、《0C的突然袭击下，细胞膜才会发生严重的膜脂过氧化作用长叶竹柏幼苗的主要代谢渗透调节物质，如可溶性糖类、游离脯氨酸和可溶性蛋白质含量变化都与长叶竹柏幼苗的抗寒性密切相关，但又不尽不同。

In the osmotic adjustment, soluble sugar had the primary function under the early stage of drought stress, while it was praline under the late stage of drought stress.

在渗透调节上，刺槐在干旱胁迫初期可溶性糖起主要作用，在胁迫后期脯氨酸起主要作用。

There was a little difference betweenphotosynthesis characteristic of the two varieties,response of Jiamusi to low temperature andpoor light was more sensitive than that of Longjiao No.2 and decreased pronouncedly withdecreasing light.6.EC and MDA of pepper leaves increased under low temperature and poor light,therewere no significant differences between them with decreasing light at 21-23℃/8-10℃,butthey were increased dramatically at 15-20℃/5-6℃.So we can speculate that lowertemperature was the direct reason resulted in cell membrane lipid peroxidation.7.No significant difference of SOD activity was observed under suboptimal temperatureand poor light21-23℃/8-10℃;150μmol·m~(-2·s~(-1),but SOD and POD activity substantiallydeclined with lowering temperature and light as well as treatment time.8.Under suboptimal temperature and lower light,proline accumulated to increaseosmotic regulation capacity and alleviate chilling damage.Soluble carbohydrate of pepper leaves decreased progressively and significantly with decreasing temperature and lightintensity as well as longer treatment time.So we think that synthesis and transport ofphotosynthetic product were inhibited by low temperature and poor light as solublecarbohydrate was important component of photosynthetic product.

两个供试辣椒品种之间的光合特性略有差异，佳木斯对低温弱光的反应比陇椒2号敏感，尤其随光照降低，其光合作用显著降低。6、低温弱光胁迫下，辣椒叶片的相对电导率和丙二醛含量都有不同程度的提高，在偏低温下，随着光照减弱，相对电导率和丙二醛含量差异不显著；在极端低温下，随着光照进一步减弱，相对电导率和丙二醛含量明显提高，随着处理时间延长，同一温度下，随着光照降低，叶片丙二醛含量也显著增加，由此可初步判断，低温是导致细胞膜脂过氧化的直接原因。7、经偏低温较弱光21～23℃／8～10℃、150μmol·m~(-2·s~(-1)处理后，辣椒叶片的超氧化物歧化酶活性变化与对照无显著差异，但随着温度、光强的逐步降低和处理时间的延长，SOD、POD活性显著降低。8、在偏低温较弱光下，辣椒能积累更多的脯氨酸，增强渗透调节，减轻低温冷害。

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