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

摘要

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