Abstract:
INTRODUCTION

Ornamental attributes of many native shrubs and small trees have been recognized, but some taxa remain rare in commerce, and little information on propagation is available. Availability of plants for restoration projects also remains limited while the demand for propagules for such projects is on the rise. Many species with horticultural merit also have become rare in the wild, in part due to destruction of their natural habitat for anthropogenic use, and at times because of over collection of wild plants from natural areas. Such losses prevent horticultural assessment of native plants and increase our reliance on non-native species that do not reflect a region’s natural heritage, may become invasive, or may introduce pests and pathogens. Use of native plants in natural and managed landscapes can help contribute to preserving the overall biodiversity and the within-species genetic diversity of indigenous taxa while providing attractive alternatives to the more common, homogeneous landscapes.

Approximately two-thirds of North American woody species exhibit some form of seed dormancy (Schopmeyer, 1974), and inhibitors to germination can develop at various times during seed development (Bradbeer, 1988).
