Abstract: 
Selenium (Se) is not an essential nutritious element for plants; although, the element is absorbed by them. Molybdenum (Mo) is a trace element/heavy metal, a potential toxicant in plants and other organisms in high amounts. We investigated the effects of Se-Mo interactions on the contents of photosynthetic pigments in tomato (Lycopersicom esculentum Mill. Cv. Early Urbana111). Chlorophylls a and b, beta-carotene and xanthophylls were spectrophotometrically measured (Jenway, UK) in leaf extract samples. Dry weight was also recorded. Se showed no significant effect on shoot dry weight, but statistically significantly reduced root dry weight. Also, Se increased the contents of photosynthetic pigments. Mo had toxic effects as it linearly decreased total dry weight and significantly reduced the contents of leaf photosynthetic pigments. Se detoxified Mo at 1- and 2ppm levels. It was concluded that Se is able to improve Mo-related stress symptoms.
