The results indicate seawater concentration has no effect on absorbency, pH, relative density, dry matter and water contents in Aloe vera leaves. While, seawater stress causes increased MDA and membrane penetration, decreased phytochroms, prolines and NO_3~--N. It is beneficial to plant growth when irrigation was done with 10% seawater, because of higher ratio of K~+/Na~+ and lower ratio of Na~+/Ca~(2+). In addition, the polysaccharide contents in Aloe vera leaves increase twice and triplication under 25% and 50% seawater irrigation respectively, the barbaloin contents increase over triplication in var. 75% seawater and over twice in var. 50% seawater and var. 100% seawater. However, when seawater concentration exceeds 25% the growth of plant was inhibited, biomass decreased, flowering time was deferred, Ca~(2+) content decreased caused by Na~+ accumulation in leaves.

结果表明：在海水胁迫下，库拉索芦荟全叶汁的吸光度、酸度、相对密度、总固形物和水分含量总体上受海水浓度的影响不大；但芦荟叶的丙二醛含量和质膜透性增加，叶绿体色素、脯氨酸和硝态氮含量减少；在10％海水浇灌下，芦荟叶细胞具有较高的K~+／Na~+比和较低的Na~+／Ca~(2+)比，对库拉索芦荟的生长有一定的促进作用；在25％海水和50％海水浇灌下，芦荟多糖含量提高了2-3倍；在75％海水浇灌下芦荟甙含量增加了3倍多，在50％海水和100％海水灌溉下，其含量也增加了2倍多；当海水浇灌浓度超过25％后，库拉索芦荟的生长明显受到抑制，生物量降低，抽苔期推迟，同时，海水浓度的增加也导致芦荟叶中累积大量Na~+，从而使得芦荟叶中Ca~(2+)含量降低，但Mg~(2+)并没有受到海水浓度的影响；用浓度低于75％的海水浇灌库拉索芦荟可以降低剖面深度在0-100cm之间的土壤盐度；其抗氧化保护酶中超氧化歧化酶的酶活力相对保持稳定，过氧化物酶的酶活力在10％海水浇灌下明显提高，随后则下降，而过氧化氢酶的酶活力则随海水浓度的升高而下降。

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.
