Abstract The effects of different seawater concentrations on seed germination，growth and quality were studied in this paper，using 4 kinds of vegetables varieties，including three pakchoi（Brassica campestris L.var. communis Tsen et Lee）varieties‘ Gailiangjingchunlyu’，‘Qibaoqing’，and‘ Shanghaikangre605’，and one Kale（Brassica oleracea L. var. acephala DC.）variety‘ Dongfanglyunen’as experimental materials. The results showed that‘Gailiangjingchunlyu’has the strongest seawater-tolerance among these 4 vegetables. Its seed germination rate could reach 100% when seawater concentration was between 40% and 60%，and when seawater concentration reached to 80%，its seed germination rate could still reach 40%. When seawater concentration were 40%，the contents of soluble protein，chlorophyll（except‘Shanghaikangre605’），VC and β-carotene in these 4 vegetables were all higher than that of the contrust by 142.5%，99.2%，101.5% and 117.5% in soluble protein concentration，59.0%，18.4% and 16.8% in chlorophyll production，101.0%，75.9%，31.2% and 5.2% in VC content，77.8%，48.9%，77.5% and 51.9% in β-carotene content respectively. These results indicated that certain seawater concentration could improve the nutritional quality of vegetables.
