Abstract

Antimony is a toxic heavy metal for plants, animals and human being. Considering its effects on plants growth, different concentrations on watermelon growth and development were studied. The experiment was established on a factorial experiment based on a completely randomized design with 3 replications. The seedlings were grown hydroponically in nutrient solution containing Sb-EDTA (0, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6 and 8 mg/L). Samples were harvested after four weeks to determine biochemical and morphological parameters. With increasing Sb concentration in culture medium, resulted in significantly decreased chlorophyll content and some other growth parameters in treated plants (p
