ABSTRACT

FELDA Agricultural Sdn Bhd (FASSB) has been exploiting various germplasm and advanced materials to broaden the narrow genetic base of its breeding population since 1968. The utilisation of these materials has resulted in more than 200 progeny test trials. From a total of 25 progenies analysed in this study, performance tended to group the teneras, according to their pisifera sources. Cluster analysis shows that the pisifera Dumpy AVROS and La Me were closely related populations in terms of performance while the pisifera Yangambi was the most different pisifera group. The highest bunch weight production was dominated by all the DxP (Yangambi) progenies for the young mature, mature and eight-year mean periods at 130.42, 217.00 and 175.34 kg palm‾¹ yr‾¹, respectively. In addition, DxP (Yangambi) progenies also scored highest for oil to bunch ratio at 29.50%, which differed significantly from the other pisifera sources. The highest bunch index and bunch dry matter were also attained by DxP (Yangambi) progenies at 0.41 and 12.65 t ha‾¹ yr‾¹, respectively. The highly significant differences indicated in the bunch yield, bunch components, vegetative and physiological traits from the analysis of variance revealed the existence of genetic variability among these traits which may allow for further improvement and exploitation.

ISOLATION AND FUNCTIONAL PROPERTIES OF HEMICELLULOSES FROM OIL PALM TRUNKS

Approximately 80% (dry weight) of the total hemicelluloses (xylan) was extracted from oil palm trunks (OPT). Analysis of OPT gave the following composition (dry basis): 42%-45% cellulose, 26%-29% hemicellulose and 16%-18% lignin. Optimisation of the aqueous extraction was done using the following parameters: 3.0 M alkali concentration, 40°C temperature, 4 hr soaking time, 50 g […]

MICROEMULSIONS FORMED WITH PALM OIL-BASED MATERIALS AS ALL-PURPOSE SPRAY LIQUID CLEANERS FOR HAND SURFACES

This article describes the formation of microemulsions by utilising fatty acid methyl esters (FAME) and a surfactant or mixed surfactant system derived from palm oil-based oleochemicals. The effects of 1,2 hexanediol as a conventional non-toxic co-surfactant were investigated by observing the ternary phase behaviour of palm oil-based microemulsions for three types of surfactant systems, i.e., […]
