The longevity of seeds, the percentage of germina-tion and the purity of the sample have much to do withthe resulting crop. In the table on page 49, the per-centages of purity and germination (by Duvel) arc highaverages in high-grade seed; the figures (years) onlongevity are from Vilmorin. As an indication of theimportance of securing high-grade seed the followinginstance si)eaks for itself. 48 PLANT PROPAGATION.
