Abstract

The cadmium (Cd) accumulation characteristics of Lycopersicon esculentum seedlings were studied by the pot experiment, and different soil Cd concentrations (0, 1, 5, 10, 15 and 20 mg/kg) were used. With the increase of soil Cd concentration, the biomass and photosynthetic pigment content of L. esculentum seedlings had the decreasing trend. The SOD, POD and CAT activities of L. esculentum seedlings had the increase trend when the soil Cd concentration was not more than 5 mg/kg, and decreased when the soil Cd concentration was higher than 5 mg/kg. The soluble protein contents of L. esculentum seedlings had the decreasing trend with the increase of soil Cd concentrations. The Cd contents in different organs L. esculentum seedlings were ranked as root > leaf > shoot > stem. With the increase of Cd concentrations in soil, the Cd contents in roots, stems, leaves and shoots of L. esculentum seedlings increased. Therefore, the soil Cd inhibited the growth of L. esculentum seedlings.
