Abstract The purpose of this study is to explore the physiological mechanisms underlying attenuation Cd toxicity using Se in two cherry tomato cultivars ‘Hanluzhe’ (HLZ) and ‘Lvfeicui’ (LFC), with low high accumulation rates, respectively. Hydroponic experiments were conducted 2.5 μmol L −1 was applied hydroponic solution 50 Cd. photosynthetic parameter, antioxidant enzyme activities, non-enzym...
