There are experimental results as follows:(1) Eriophorum comosum Nees shows strong cold resistance in plasmalemma permeability research. The lethal temperature of Eriophorum comosum Nees is the lowest LT_(50 in comparison with another two plants and is lower than -11.5℃ in August 2005 and December 2005; Soluble protein content of each plant is rising before or after cold hardiness. By SDS-PAGE, Protein band is analysed. Band quantity of Eriophorum comosum Nees is the most and its band color is darkest.(2) Soluble sugar content of three plants after cold hardiness are higher than before cold hardiness, moreover soluble sugar content after cold hardiness shows a decline and there is a narrow range in Eriophorum comosum Nees; Free Proline accumulation is changed by cold stress, and cold resistance is relative to free Proline accumulation; chlorophyll content of both three plants, including chlorophyll a, chlorophyll b and chlorophyll a/b, show a decline tendency along with the descent of temperature. Cynodon dactylon is highly sensitive to cold stress.(3) The soil POD and urease activities' absolute value of Erioophorum comosum Nees and Pogonatherum panideumHack were more than that of Cynodon dactylon before or after low temperature stress, especially POD activities.

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。
