Physiological traits of cauliflower cultivars “Clapton” and “Graffiti” after fortification with sodium selenate (Na₂SeO₄). In each column, same letters are not significantly different at the1% and 5% level based on Duncan’s multiple range tests with three repetitions (Chlorophyll and Carotenoid in leaves, Antioxidants, Phenol and Se concentration in floret).
