Fig. 2From: Partial and full root-zone drought stresses account for differentiate root-sourced signal and yield formation in primitive wheatChanges in production rate of reactive oxygen species (O2−) (a), hydrogen peroxide concentration (H2O2) (b), and osmoprotectants, such as proline (c) and malondialdehyde (MDA) concentration (d) in the leaves at the flowering stage of four primitive wheat varieties, MO1, MO4 (diploid); DM22 and DM31 (tetraploid). Values are mean ± SE (n = 3). Trial 1Back to article page
