Dormancy in Western Ironweed and Leafy Spurge
Published online by Cambridge University Press: 12 June 2017
Abstract
Internal dormancy was shown to occur in western ironweed (Vernonia baldwinni Torr.) and leafy spurge (Euphorbia esula L.) in late summer and fall. Time required for emergence and extent of growth were important indicators of dormancy. Dormancy is apparently broken naturally in the field by low soil temperatures.
