Abstract
Taking tomato cultivar ‘Liaoyuan Duoli’as material,the EC value of the nutrient solution was improved by adding different concentrations of NaCl in the fruit development period,and the effect of high EC on the fruit yield,quality and sucrose metabolism of tomato in water culture were studied.The results showed that 3high EC treatments increased soluble sugar,organic acids and vitamin C content in mature fruit,and higher EC more obvious.With the improvement of EC value in nutrient solution,hexose(fructose+glucose) content in every part of tomato increased,invertase(acid invertase+neutral converting enzyme) activity enhanced,hexose content and invertase activity increased mainly in 40～60days after flowering.The above suggested that the increase of soluble sugar content of tomato in fruit development period under high EC management was due to enhancement of sucrose conbersion enzyme activity;the fruit quality improved the most,and dry matter weight lost the minimum under EC value treatment from 1.25,2.5,3.8to 5.2in this experiment.
