Abstract:Seedlings of American elm (Ulmus americana, L.) were subjected to chilling temperatures for periods ranging from 15 through 60 days and to photoperiods ranging from 6 through 19 hours. Results show moderate chilling treatment and an extended photoperiod are most effective in giving maximum hud break in the shortest length of time. Data also indicate temperature may be a significant factor in determining bud break, especially if photoperiod is limiting.
