An 18-hr photoperiod (LD) significantly increased cambial activity, rooting, bud respiration, and also hastened bud break of stem cuttings as compared with similar cuttings propagated under a 9-hr photoperiod (SD). Rooting response was modified by sampling date and temperature of the rooting medium. Rooting was least from August through November and greatest in December and January. Rooting temperatures of 18 and 26°C enhanced rooting without affecting bud activity.
