Techniques for the successful vegetative propagation of forest tree species by cuttings are urgently needed. This implies that practical methods as well as detailed procedures are necessary for use with individual species. It is known that optimum auxin treatments of greenwood cuttings of red and sugar maple stimulate rooting considerably. Several factors concerned with obtaining maximum rooting response are the time of year cuttings are obtained, specificity and concentration of certain growth substances, and the length of treatments. Another complicating factor in obtaining consistent results with red maple particularly is the large amount of variability between individual clones. Experiments dealing with these and other factors are reported in this paper.
