Abstract:: In order to explore the mechanism of plant growth under the influence of salt and pesticides，taking Brassica oleracea var. botrytis L.as test materials，the effect of seed germination percentage and seedling growth of under NaCl-acephate combined stress with NaCl concentration as 0.0%,0.2% and acephate concentration as 0.00%,0.03%,0.06%,0.09%,0.12% were studied.The results showed that the seed germination percentage，root length，seedling height，number of lateral roots，seedling fresh and dry weight were reduced with NaCl-acephate combined stress；Salt resistance of Brassica oleracea var. botrytis L.appeared with NaCl concentration as 0.2%，while sensitivity of Brassica oleracea var. botrytis L.to acephate treatments appeared with acephate concentration as only 0.03%;salt stress increased the effects of acephate stress on plants.So the research would give us good advice on how to plant Brassica oleracea var. botrytis L.using saline-alkali soil and how to do screening of Brassica oleracea var. botrytis L.germplasm with acephate resistance and salt resistance.
