Offspring generation
The number of nodes on the main stolon, number of branches and growth rate of the main stolon and branches significantly differed among the genotypes (Table 1). Number of nodes on the main stolon, number of branches and growth rate of the main stolon and branches were also significantly affected by the time period since the last drought (Time since the last drought, Table 1). Biomass of offspring ramets produced by parental ramets that experienced last drought event 2, 4 and 6 weeks before transplantation was higher compared to offspring biomass of parental ramets from control conditions (Fig. 3, Table 2). Number of nodes of the main stolon was higher for offspring of parents that experienced last drought event 4 and 6 weeks before transplantation compared to offspring of other drought treatments (Table 2). Plants of parental ramets that experienced last drought event 4 weeks before transplantation produced more branches than plants of other parental drought groups (Table 1, Fig. 2). The growth rate of node number of the main stolon and number of branches was lower in plants created by parental ramets that experienced last drought event 2 and 8 weeks before transplantation in comparison to other treatments (Table 2).
