Cuttings of aspen root suckers were rooted in aqueous medium under controlled conditions. Various concentrations of idole-3-acetic acid (IAA), gibberellic acid (GA), kinetin, and abscissic acid (ABA) were tested. IAA stimulated the number of roots per cutting, whereas GA and kinetin inhibited root numbers. ABA had no effect on number of roots at the concentrations tested. The distilled water controls exhibited seasonal variability in root numbers with respect to the date cuttings were harvested for rooting tests. Forest Sci. 18:21-22.
