Abstract

Even though current forest plantation practices in Malaysia are focusing on planting exotic species such as Acacia mangium and Eucalyptus sp. several disease incidences such as wilt disease had caused significant losses to the planters. Therefore FRIM has taken an initiative to explore indigenous species such as Shorea roxburghii which has the potentials to be grown as a forest plantation. S. roxburghii or locally known as meranti temak nipis is from the family of Dipterocarpaceae. Generally this species is harvested from the natural forest for its timber. Many reforestation efforts in Malaysia and Indonesia have proved that S. roxburghii is a robust species with a high survival rate and considerably fast growth for indigenous species. Several studies on silviculture practices reforestation and rehabilitation using the S. roxburghii species have been conducted but none focuses on the genetic resources of the species. Therefore improvement through the selection of plus trees has been initiated with the main objective to provide high-quality planting materials resources. In this study the variations on the growth performance among the families grown at different sites will be evaluated. The study was started with the seeds collected from the 27 selected mother trees. The seeds were then germinated and grew at nursery until mature before the establishment of the progeny trial plots at three FRIMs research station (SPF); SPF Jeli (Kelantan) SPF Mata Ayer (Perlis) and SPF Setiu (Terengganu). The progeny trial plots were laid out in Randomized Complete Block Design (RCBD) with a total of 3240 seedlings; SPF Jeli (864 seedlings) SPF Mata Ayer (1296 seedlings) and SPF Setiu (1080 seedlings). Upon the establishment of the progeny trial plots the growth data were collected every three months interval. This paper will be discussing the findings on the survival rates and early growth performance (16 months old) of the 27 families. The assessment of the height (HT) parameter at 16 months old showed that there were high variations among the Site Family and Site by Family interactions with p values 0.000. Survival rates of the seedlings were very promising varied from 81.9 (SPF Jeli) to 96.4 (SPF Mata Ayer) whereas SPF Setiu scored 95.7. In terms of growth performances seedlings at SPF Jeli scored the highest overall HT (152.4 cm) followed by SPF Mata Ayer (107.97 cm) and SPF Setiu (92.7 cm). Whereas for the families variations the top three highest HT scored by the families F22 (128.4 cm) F38 (125.98 cm) and F48 (125.92 cm). The forthcoming outcome from this study would be an improved seeds sources for high quality planting materials. Besides the progeny trial plots could be converted into Seedlings Seeds Orchards which would also serve as germplasms in an effort towards genetic conservation.
