Abstract: In this study}the seeds of 27 types of vegetable crops,Cruciferae,Cucurbitaceae,Solanaceae,Leguminosae,Umbelliferae and Liliaceae were treated with NaCI solution of different concentrations. We preliminarily got the suitable concentration, the critical concentration and the lethal concentration. The result showed that the reaction of different vegetable crops was different under salt stress. With increasing of NaCI concentration the seed germination rate gradually deceased. Part of the Cruciferae vegetable crop seeds can adapt to a low salt stress and the low salt stress had promotion effect on seeds germination. The relative germination rate of vegetable crops existed negative correlation with salt concentration. According to the critical concentration,Liliaceae,Cruciferae were the most tolerant Solanaceae was the least tolerant Cucurbitaceae,Umbelliferae,Leguminosae were the medium tolerant to NaCI stress.

Key words: NaCl stress, Vegetable crops, Salt tolerance
