摘要

Experimental plantings of different genotypes of cottonwood were examined. The four clones tested were: a Populus hybrid (Dula, D-01), a P. trichocarpa x P. deltoides hybrid (Hybrid 11), and two native P. trichocarpa clones (Nisqually 1 and Orting 5). Establishment success and characteristics of hardwood cuttings or resulting plants that might be related to success were determined. Establishment success varied significantly (P less than 0.01) among the four clones in the order, Orting = Dula greater than Hybrid 11 greater than Nisqually. Also, there was much variation among the clones in the relative proportion of inter-nodal shoots, dead buds, and 'spent' buds. Results suggest that best establishment and growth are achieved when cuttings have a health axillary buds at planting. Establishment success from such cuttings would be fairly high, and resulting experimental plantings would permit valid comparisons of productivity of different genotypes of cottonwood.
