Abstract

Information is given concerning the germination and early establishment of 30 prairie species. A stratification treatment was included for all seeds, and scarification was also used for the legumes. Germination percentage in greenhouse flats was generally higher than in field plots with variation in germination ranging from 96% in compassplant, Silphium laciniatum, to zero in some such as Rosa suffulta and Gentiana puberula. Seedlings in field plots were subjected to five levels of competition throughout the growing season. Establishment, measured by numbers of seedlings and vigor in September, was most successful on weed free treatments, least successful on cover crop treatments.
