A species/ provenance/progeny trial was established in August 1998 at Kampung Aur Gading, Kuala Lipis. The research was part of a collaborative effort between the Universiti Putra Malaysia (UPM), and the Fuel wood / Forest Research and Development Project (F/FRED) and the Australian Centre for International Agriculture Research (ACIAR) to evaluate the Genetic Variation in Fluorescence Efficiency of these species /provenances in Malaysian environment and to access the genetic worth of selected parents. The study involved the assessment of growth performance of two and an half year old Acacia mangium, Acacia auriculiformis, Acacia crassicarpa and Acacia aulococarpa trial plot at Kampung Aur Gading, Kuala Lipis, Pahang. The materials used in this trial comprised 80 progenies of the four species mentioned of which 20 progenies from each species. No significant variation was found in fluorescence efficiency between the species/provenances despite significant variation were detected in the growth performance between the species, provenances as well as among progenies. Morphological character such as leave size was observed to have given significant effect on the growth of these Acacia as they were grown together side by side. Acacia mangium appeared to give the best growth as it dominated the others. The result also revealed that physiological character such as fluorescence efficiency could not serve as on of the selection tool for advance breeding population for further improvement.
