Abstract
Germination of seeds of 91 species of prairie plants was studied by stratification and scarification techniques. In a group of 51 spp. stratification was beneficial for 73% and harmful for 14%, while in a group of 12 spp. with hard seed coats scarification was beneficial for 83% and harmful for 8%. Germination values for the same spp. under comparable conditions fluctuated greatly for seeds collected in different yrs.
