The significance of population successional status to the evolution of seedling morphology in Pinus contorta var. latifolia (Pinaceae)

Abstract

A greenhouse study of lodgepole pine (Pinus contorta var. latifolia) seedlings tested the hypothesis that the successional role of a population, because of its influence on selection, partly determines autecological evolution. Seeds came from seral, climax, and persistent populations in the Blue Mountains of NE OR and SE WA. Indeed, greater
