Parental plants of the first phase
Parental biomass differed among the genotypes (mean±SE, genotype A: 24.50 g ± 3.87; genotype B: 17.87 g ± 2.83; genotype C: 24.21 g ± 3.83) and was affected by the time period since the last drought (Table 1). Control plants were the biggest whereas the plants that received drought treatment were on average of half of the size of control plants. Parental plants with the last drought treatment 8 weeks before transplantation were the biggest and the parental plants that received last drought 14 days before transplantation the smallest among the plants that received drought stress (Fig. 1S). There was also a significant interaction between 5-azaC and time since the last drought (Table 1). Application of 5-azaC only decreased the parental biomass in 4 W (Table 1, Fig. S2).
