West Eugene Native Wetland Restoration Research Project: Seed Dormancy, Germination, and Establishment

Creator:

Wilson, Mark V., Ingersoll, Cheryl A., and Clark, Deborah Louise, 1950-

Abstract:

Seed size, abundance, viability, dormancy, and germination requirements strongly influence plant establishment and therefore are important considerations in restoration of native vegetation. These characteristics provide criteria for selection of suitable species, development of collection and pretreatment methods, and determination of seeding densities. The first set of objectives of this study...
