Temporal variations in the rooting ability of cuttings of Populus balsamifera and Salix planifolia from natural clones–populations of subarctic Quebec
Temporal variations in the rooting ability of cuttings from five clones of Populusbalsamifera L. and five populations of Salixplanifolia Pursh from the Great Whale River valley in subarctic Quebec were determined. Cuttings were sampled monthly from May through October and rooted in a greenhouse. Roo...

Temporal variations in the rooting ability of cuttings from five clones of Populusbalsamifera L. and five populations of Salixplanifolia Pursh from the Great Whale River valley in subarctic Quebec were determined. Cuttings were sampled monthly from May through October and rooted in a greenhouse. Root number and length of the longest root per cutting were determined 35 days after planting. There were significant variations among the six sampling dates in the rooting potential of cuttings of both species. A higher percentage of cuttings formed adventitious roots in May and June before or shortly after bud break than later, during the growing season; root number and length followed a similar trend. There was an increase in the rooting ability of cuttings of both species towards the fall period. Salixplanifolia produced more roots per cutting than P. balsamifera early in the season (i.e., May and June), but later in the season the differences between the two species were not great; root length showed no such trend.
