Winter Survival of Grasses and Legumes in Subarctic Alaska as Related to Latitudinal Adaptation, Pre-Winter Storage of Food Reserves, and Dry-Matter Concentration in Overwintering Tissues

Abstract

similar experiments, were to (a) compare winter hardiness in subarctic Alaska of numerous plant species and ecotypes from various latitudinal sources within most species, and (b) seek a better understanding of certain aspects of pre-winter physiologic changes in plants that are associated with successful or with unsuccessful winter survival in this northern area. Both experiments were conducted at the University of Alaska’s Matanuska Research Farm (61.6°N) near Palmer in southcentral Alaska
