Abstract

Excellent nursery trees of several clonal apple rootstocks were produced in these tests 11 months after hardwood cuttings were planted. Preplanting treatments with indolebutyric acid followed by bottom heat at the base of the cuttings, while the tops were exposed to normal winter chilling, were necessary. This method could replace the more expensive and slower “stooling” method of propagating clonal apple rootstocks.
