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.

Along with seawater stress strength upward, the ratio of root to shoot, Na+, Cl- and soluble sugar contents were increased significantly. Under the 10% and 20% seawater treatments, chlorophyll contents have no obvious difference compared with the control, but significantly decreased when the seawater stress further increased. Under the 10% seawater treatments, K+ contents in the shoot and root of Lactuca indica seedlings have no distinct difference compared with the control, but along with seawater stress strength upward, K+ content were markedly decreased by degrees.
