“…Similar results have been reported for other plant species (Banyai et al, 2010;Majdi et al, 2010;Mishra et al, 2010;Caruso et al, 2011;Dehghan et al, 2012;Abdoli et al, 2013;Lavania, 2013;Dixit and Chaudhary, 2014). Phenolic compounds are active in pathogen resistance, pigment production, and protection against ultraviolet radiation (Winkel-Shirley, 2001); they also qualitatively and quantitatively improve the biochemical profile of plants (Maruška et al, 2010). Polyploidy often enhances the expression and concentration of some secondary metabolites and defence chemicals (DeJesus-Gonzalez and Weathers, 2003;Jones et al, 2008;Nilanthi et al, 2009;Dhooghe et al, 2011;Dehghan et al, 2012;Hsia et al, 2013;Gomes et al, 2014;Zahedi et al, 2014).…”
