Effects of crude plant extracts on wounded Ricinus communis plants
Journal Title: European Journal of Biological Research - Year 2016, Vol 6, Issue 2
Abstract
The effects of mechanical wounding with or without crude extracts of neem (Azadirachta indica) and Citrullus colocynthis (CCT) supplementation on hydrogen peroxide (H2O2), lipid peroxidation (MDA), ascorbic acid (Asc A), phenolic compounds, and some enzymes activities in Ricinus communis plants were studied. In response to mechanical wounding Ricinus plants produced more ascorbic acid, MDA, free and bound phenolic components and to less extent H2O2. On the other hand, peroxidase, catalase and SOD activities were declined upon wounding as compared with unwounded plants. Neem and CCT crude extracts application, whether independently or in combination, counteracted in various degree the deleterious effects of wounding stress on the parameters tested. Effectively, their supplementation increased the antioxidant defense ability through enhancement of ascorbic acid, reduction of H2O2 and MDA intensities. In addition, crude extracts reduced membrane injury, increased phenolic components and improved wounded plants growth. The results clearly indicate that the protection by CCT and neem crude extracts may be mediated through the modulation of cellular antioxidant levels.
