Abstract

In the absence of quality seeds for massive rehabilitation and restoration of degraded forest lands, the use of vegetative parts of plant like stem as planting material, is a feasible alternative. However, there are reports indicating the morphological differences between cuttings and seedlings, hence, gauging the extent of how such differences could affect the growth and performance in the field. This study compares the growth (height and diameter) and survival of the macropropagated and seedlings of Narra (Pterocarpus indicus Willd.) in the established field trail plantation in Davao Region of Mindanao. Three hundred seedling materials were evaluated. After 2 years, survival in the stock-type trials was 96% for rooted cuttings, and 98% for seedlings. Mean diameter and height ratios revealed that rooted cuttings are better than seedlings with 14.42mm and 121.51cm: 13.98mm and 119.81cm, respectively. Despite the differences of cloned and seedling results, differences in size and relative growth rates had no significant differences between treatments.
