Abstract

The planting stocks raised from rooted stem cuttings of two Dipterocarp and five non-Dipterocarp species were planted in Field 48, Bukit Hari, Bukit Lagong Forest Reserve, Kepong, Selangor, Malaysia. Seven years after planting, the survival of Dipterocarp species planted were 87% for Hopea odorata and 95% for Dipterocarpus chartaceus. Mean annual height increment (hMAI) of H. odorata was higher (106 cmy-1) than D. chartaceus (78 cmy-1). The mean annual diameter increment (dMAI) of H. odorata was 1.4 cmy-1. The diameter increment for D. chartaceus is not yet available due to the slow growth of this species. For the non-dipterocarps, Khaya ivorensis had the highest survival rate (88%) followed by Endospermum diadenum (71%), Azadirachta excelsa (49%), Pouteria malaccensis (28%) and Dyera costulata (20%). In terms of hMAI, K. ivorensis had the highest increment (269 cmy-1), followed by E. diadenum (262 cmy-1), A. excelsa (148 cmy-1), P. malaccensis (141 cmy-1) and D. costulata (137 cmy-1). The dMAI for E. diadenum and K. ivorensis were higher (2.6 and 2.3 cmy-1 respectively) compared to those of P. malaccensis, D. costulata and A. excelsa which ranged from 1.2 to 1.8 cmy-1). The results showed that the planting stocks raised from rooted cuttings can be used as an alternative planting material for plantation.
