The germination of three groups of seeds of the plant $\textit{Penstemon digitalis}$ was studied. The seeds were soaked for 24 hours in distilled water or in a gibberellin solution. They were then placed on filter paper in dishes and kept moist for 10 days. Fig. 6.2 presents the results for each group.
