Indolebutryic acid and wounding induced rooting in callused, non-rooted Leyland cypress (× cupressocyparis leylandii) stem cuttings

Abstract

Callused, non-rooted Leyland cypress (× Cupressocyparis leylandii) stem cuttings were treated with different wounding treatments (no, single and double wound) and solutions of indolebutyric acid (IBA) (0,5000, and 10 000 ppm). Double wound and 10 000 ppm IBA resulted in the highest percentage of rooted cuttings compared with all other treatments. Wounding had no effect on the number of primary roots produced per rooted cutting, however, cuttings treated with 10 000 ppm IBA formed significantly more roots than non-treated cuttings (4.5 and 2.6, respectively). © 2005 Taylor & Francis Group, LLC.
