The effects of pre-sowing He-Ne laser seed treatment on secondary metabolites and nutritional value in sunflowers. For each trait, means with the same letters, do not differ significantly from each other at P ≤ 0.05. Data are presented mean ± standard deviation (n = 3 independent biological replicates). (K) Phenolic content, (L) Total flavonoid content, (M) Anthocyanin, (N) Carotenoid contents, (O) Metabolizable energy, (P) Nutritional value. Statistical significant differences determined by LSD (P < 0.05) are denoted by a, b, c, d.
