A METHOD FOR VEGETATIVE PROPAGATION OF DRYOBALANOPS LANCEOLATA (DIPTEROCARPACEAE) BY CUTTINGS

Abstract

Two-node cuttings were prepared from the apices of juvenile seedlings of D. lanceolata. Leaves were trimmed reducing leaf area to approximately 30 cm² and the basal end of each cutting was treated with a fungicide solution (0.1 % w/v Benlate) followed by 3 % NAA powder. Cuttings were rooted in a closed chamber mist propagator. After roots formed, cuttings were potted in 7 X 21 cm polybags and weaned for two weeks in high humidity chambers. Percentage rooting after 12 weeks was 80 %. Mortality in the weaning-off stage was around 6 %.
