The effects of pre-sowing He-Ne laser seed treatment on primary metabolites in sunflowers. For each trait, means with the same letters do not differ significantly from each other at P ≤ 0.05. Data are presented as mean ± standard deviation (n = 3 independent biological replicates). (E) Soluble sugar content, (F) Total soluble proteins, (G) Reducing sugar content, (H) Free proline content, (I) Percent oil content in the leaf, (J) CAT activity. Statistical significant differences determined by LSD (P < 0.05) are denoted by a, b, c.
