Abstract

The effect of cold storage on suckering ability of excised roots was determined for 10 aspen clones. Root cuttings were collected in June, August, and October and stored for from 7 to 42 days at 2°C. In addition, cuttings from dormant trees were stored for 175 days to determine if they had cold requirements for suckering. Among clones, there were large differences in capacity to produce root suckers. Cold storage had a small but significant effect on the formation and growth of suckers on root cuttings collected in June and August. As a rule, clones responded similarly to cold storage. Sucker production by root segments from dormant trees was relatively high and was not increased significantly by storage. Incidence of callus formation at the ends of root segments tended to increase with time in cold storage.
