Setup of the experiment. The 7-day drought priming events (NP- no priming, DP- drought priming) were successively applied in the 1st, 2nd, and 3rd growth season (experimental year), the 5-day drought stress (NS, no drought stress; DS, drought stress) was conducted in the 4th year. Both the drought priming and the drought stress were initiated at 10 days after anthesis. In total, eight treatments were given: 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.
