The induces changes in growth and physiology of basil (Ocimum basilicum L.) by foliar application of selenium and methionine

To investigate the possible individual and combined effects of selenium (Se) and methionine in basil plants, the current study was carried out. Seedlings were foliarly treated with 2 concentrations of Se (0 and 40 mgl-1) and/or 2 levels of mrthionine (0 and 200 mgl-1). The obtained findings indicated that contents of photosynthetic pigments, including Chla, Chlb, and carotenoid was influenced by the applied supplements, in way Se had an increasing effect, contrasted with methionine. The applications of Se and/or methionine led to induction of peroxidase enzyme. Methionine provoked reduction in growth related charachtristics, including plant height and leaf fresh mass. The applied level of Se did not have condiserable beneficial effect on the plant growth. Therefore, this concenteration of Se may be utilized for biofortification to improve plant resistance via inducing antioxidant enzymes, and enhancing carotenoid content.
