a Germination rate (%) of the different oak species. The “N” corresponds to the number of sub-batches analyzed. b Correlation between mean germination time in days and the germination rate (%). The colors of the points indicate the different species, and they correspond with the colors of the map in Fig. 1. Each point is the data from one sub-batch
