Abstract：Soaking treatments were simple and effective measures to improve the quality of vegetable seedlings.In the study,tomato was used as material to test the effect of different concentration (100,200,300,400 mg/L) of choline chloride on seedling growth and partial physiological indexes of tomato by soaking seed using distilled water as control.The results showed that compared with the control,suitable choline chloride soaking treatment promoted the tomato seedling growth,increased the plant height,stem diameter,fresh weight and plant dry weight,and hence improved the seedling index.The optimal concentration of choline chloride was 200 mg/L,and in high concentration(400 mg/L) treatment tomato seedlings growth was inhibited.Suitable concentration of choline chloride soaking could increase the chlorophyll content of tomato seedlings,the PSⅡ maximum photochemical efficiency,soluble protein content,soluble sugar content,and decrease MDA content.The results indicated that suitable concentration of choline chloride could increase the tomato seedling photosynthetic performance and resistance capacity,promote seedling growth and strong seedling cultivation,and the optimal concentration was 200 mg/L.
