The terminal portion of shoots was discarded; the sub-terminal
portion (Proebsting and Reihs, 1991) was cut every third node
producing 2 buds cuttings (the basal third bud was buried). Cuttings
had a mean diameter of 4.5±0.8 mm and mean length of 16.1±2.4 cm. The basal leaf was removed whereas the highest one was cut at half length. Four replicates of 20 cuttings per treatment were used for the trial.
