ABSTRACT
This chapter provides the information on uses, folk medicine, chemistry, germplasm, distribution, ecol-ogy, cultivation, harvesting, yields, energy, and biotic factors of Corylus Americana. According to Hartwell, the bark is used in folk remedies for a poultice for tumors. Reported to be a panacea, American hazelnut is a folk remedy for stomatitis and tumor. Reported from the North American Center of Diversity. The most important cvs of the American filbert are 'Rush' and 'Winkler', both very widely cultivated and the most hardy of all filberts. Four hybrids — 'Bixly', 'Buchanan', 'Reed', and 'Potomac', have been introduced; these have intermediate characteristics between European and American varieties. The cultivars of American hazelnut have smaller nuts than those of European filberts. American filberts or hazelnuts tend to sucker, the suckers should be removed promptly and the plant trained to a single stem. The nuts, which are the commercial seed, can then be sown, stratified, or stored.
