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).
