Parental generation
Parental biomass differed among the genotypes (mean±SE, genotype A: 24.50 g ± 16.45; genotype B: 17.87 g ± 13.55; genotype C: 24.21 g ± 17.06) and was affected by the time period since the last drought (Table 1). Control plants were the biggest and the plants that received drought treatment in different time slots were almost identical (Fig S1, supplementary material). There was also a significant interaction between 5-azaC and time since the last drought (Table 1). Application of 5-azaC decreased the parental biomass in control but not in any of the drought stress treatments (Table 1, Fig. S1).
