The values are means ± SD from four independent biological replicates. Small letters indicate a significant difference among Z16, H89, CN19, and XZ31 at p < 0.05 (Duncan’s multiplication range test). Z16, H89, CN19, and XZ31 present accessions of Triticum monococcum (W2n), Triticum dicoccum (W4n), Triticum aestivum (W6n), and octaploid Triticale (T8n), respectively.
