For each environmental stress treatment, values indicate 95th percentile of P-values obtained for each tested factor after simulating the initial composition of the theoretical G0 populations 500 times (see Material and Methods section). Values in bold indicate significant P-values. GERM: germination timing, BT: bolting time, INT: interval between bolting and anthesis, FLO: flowering, RP: reproductive period duration, FRR: flowering-to-reproductive period ratio.
