    Description

    Two species of dwarf mistletoe were studied: Arceuthobium abietinum (Engelm.) Hawksworth and Wiens and A. occidentale Engelm. Viability of fresh seeds was high and not significantly influenced by year of collection, where collected, or plant from which collected. Temperature affected viability most noticeably. It also significantly affected rate and percentage of seed germination. Longevity of radicles of germinated seeds was inversely proportional to temperatures above 5°C.
