Effects of parental drought-priming on contents of proline and glycine betaine in flag leaves of offspring plants under drought stress during grain filling in wheat. T0C, no former-generation priming + no offspring drought stress; T0D, no former-generation priming + offspring drought stress; T1C, one-generation priming + no offspring drought stress; T1D, one-generation priming + offspring drought stress; T2C, two-generation priming + no offspring drought stress; T2D, two-generation priming + offspring drought stress; T3C, three-generation priming + no offspring drought stress; T3D, three-generation priming + offspring drought stress. Data are means ± SE (n = 3). Different lowercase letters indicate the significant difference at p < 0.05 level.
