   Notes: The results of correlation between the quantity of sound seeds and the percentage of seedling emergence in next year are shown. We test three types of the quantity of sound seeds: seeds of all the principal tree species are combined (left); seeds of the two Fagus species are combined (center); seeds of the five Fagaceae species are combined (right).
