渗透调节

Breeding Behavior of Monosomic s in Triticum aestivum L.cv. Chinese Spring and Sava;2. Winter wheat 12057 monosomics and its euploid were evaluated for drought resis-tant physlological index.

利用12057单体及其二体连续两年进行抗旱生理指标的比较，结果表明：12057单体系与其二体在灌浆中期旗叶相对含水量、细胞膜稳定性、叶片渗透势以及渗透调节能力等均存在差异。

In addition, under the condition of drought stress, the continuous rise of the content of fusibility total sugar and proline increased the osmotic adjustment ability.

另外，可溶性糖和脯氨酸等渗透物质含量在干旱胁迫下持续升高也使其渗透调节能力加强。

Osmoregulation arising based mainly on accumulation of both proline and K+,lesscontribution of soluble sugars to osmoregulation.

叶片中脯氨酸和K+含量的快速升高是导致叶片渗透调节发生的主要原因，可溶性糖对渗透调节的贡献较小。

They avoid heavy salt loads through a combination of selective accumulation of ions, ion compartmentalization, salt excretion and salt exclusion, accumulation or synthesis compatible solutes which are mainly pinitol and mannitol for maintaining osmotic balance, and promotion of antioxidative to scavenge reactive oxygen species.

红树植物具有盐腺、叶片肉质化等形态特征，通过离子选择性积累、盐分区域化、泌盐和拒盐等机制降低体内的盐分浓度，积累或合成渗透调节物质来维持渗透平衡，增强抗氧化系统以清除活性氧。

The eco-physiological characteristics of drought endurance of Pinus sylvestris var.mongolica were studied under different climatic regions, soil water and leaf water condition.Furthemore,the response and adaptability of trees to water stress was done.The below showed the results. 1 The parameters of drought endurance of P. sylvestris var. mongolica was measure and studied by PV technology in the subhumid, semiarid and arid regions The results indicated the osmotic potentials at water saturation condition and at the initial loss turgor decreased as the climatic drought degree increased,and related linearly with the climatic moisture index.It was proved that the drought endurance of P. sylvetris var. mongolica was varible and the elevation of the osmotic adjust capability was a main way to the adaptation of trees to the drought climatic environment.

本文研究了樟子松(Pinus sylvestris var.mongolica)的主要耐旱生理生态特征在不同地区、不同土壤水分状况和叶水分状况下的变化，进而研究了樟子松对水分胁迫的反应和适应，结果如下： 1 应用 PV 技术对半湿润区、半干旱区和干旱区樟子松耐旱性指标测定研究指出，水饱和总体渗透势和初始失膨点总体渗透势随着气候干旱程度增加而增加，与气候湿度指标呈直线相关，证明了樟子松属于耐旱性可变的树种，渗透调节能力增加是其对干旱气候适应的主要途径。

Research on the osmoregulatory role of theGHGF-I axis is deried from a small number of teleost species. The study of more species with different osmoregulary patterns

对于彻底说明GH/IGH- I轴在鱼类渗透调节中的作用还需要对更多的、具有不同渗透调节特点的种类进行研究。

The results of appraisingwith the water parameters showed that all clones had the abilities toincrease osmotic adjustment and turgor maintain during water stress.

根据6项水分参数对无性系渗透调节和维持膨压能力综合评价结果表明，在水分胁迫条件下，各无性系均有一定的提高渗透调节和维持膨压的能力。

Leaf turgor loss point osmotic potential and saturation osmotic potential during the dry season were both significantly lower in all the three species, indicating a strong osmotic adjustment in adaptive to seasonal drought.

三树种叶片膨压丧失点的水势和饱和渗透势在旱季也均显著降低，表明三树种都通过较强的渗透调节来适应季节性的干旱。

Before fissuration, osmotic adjustment occurred by the addition of solute to cells and decreasing the loss of water in the body, so that it could maintain normal turgor pressure during drought. After fissurate growth, turgor pressure was maintained by higher cell and tissue elasticity lower ε(superscript max and by osmotic adjustment for normal plant development in dry conditions and to avoid dehydration under water stress during the drought period, but it also became more sensitive to water stress. The ability to maintain turgor pressure varied from strong to weak during the period before, during and after fissuration. Fissurate growth decreased the ability of P. mongolica to maintain turgor pressure and led to changes in walls related to drought tolerance.

结果表明：1未劈裂绵刺主要通过增加细胞内溶质，减少细胞内的水分丧失来进行渗透调节，从而在干旱胁迫下能够维持正常的膨压。2己劈裂绵刺通过渗透调节和高的组织弹性两条途径来共同保持膨压，以抵抗不良的生存环境；同时对环境水分胁迫具有较高的敏感性。33种状态绵刺保持膨压的能力由强到弱依次为：未劈裂绵刺、正在劈裂绵刺、已劈裂绵刺。4劈裂的发生导致绵刺保持膨压能力的降低，同时耐旱方式和途径发生了变化。

The osmoregulation of Aloe vera seedlings was stronger under water stress than under iso-osmotic NaCl treatment, the main osmoregulatory substances of Aloe vera seedlings were soluble sugars, organic acids, K〓, Ca〓 and Cl〓, strong osmotic osmoregulation of Aloe vera under water stress was mainly caused by accumulation of organic solutes.

水分胁迫下芦荟幼苗的渗透调节能力高于等渗盐分胁迫，主要渗透调节物质可溶性糖、有机酸、K〓、Ca〓和Cl〓，有机溶质含量高是水分胁迫下渗透调节能力较强的主要因素。
