Malaysian Palm Oil Board (MPOB)
The role of water deficit in oil palm is discussed in this paper. Factors such as evapotranspiration, relative humidity and vapour pressure deficit affect the carbon assimilation process and oil palm growth in general. Various irrigation techniques have been tried to overcome this water deficit and some of the results are discussed. Abstrak: Peranan defisit […]
Changes in the melting points of palm oil (PO), sunflower oil (SFO), palm kernel olein (PKOo) and their blends thereof before and after chemical interesterification (CIE) were studied by the dropping point (DP) method. PO and binary blends of PO/SFO at 3:1 ratio, PO/PKOo at all ratios and ternary blends of PO/SFO/PKOo at 4:1:1, 1:1:4 […]
The Malaysian Palm Oil Board (MPOB) studied the effects of applying oil palm empty fruit bunches (EFB) to oil palm planted on bris soil. Several combinations of EFB with inorganic fertilizers were also tested. The results showed that with proper management, bris soil with no water limitation has the potential to be developed for oil […]
Previous oil palm simulation models such as OPSIM and SIMPALM have relied on direct measurements of vegetative biomass and biomass production as a basis for predicting total biomass production and bunch yield. To overcome the limitations imposed by the need for extensive on site measurements, methods of simulating vegetative biomass production (VBP) are needed. This […]
The trunk represents an important component of the vegetative dry matter of oil palm. This paper describes the approaches taken to model trunk growth as part of a comprehensive model of oil palm dry matter production and development, and the problems and limitations encountered. Several approaches are described including the independent simulation of trunk height […]
The ability of the fungi, Aspergillus niger and Aspergillus terreus, to degrade palm-based flexible polyurethane foam was determined via the petri dish and shake flask tests. A dense fungal growth was detected by visual examination of foams inoculated on minimal nutrient agar/solution (MN)but not on the mineral salts agar/solution (MS). Both the palm-based and commercial […]
Red palm olein (RPOo) containing a high content of carotene was compared to other vegetable oils and their blends. Blends of different ratios of RPOo and refined, bleached and deodorized palm olein (RBDPOo) were used in a cake for-mulation. The ratios were A (30:70), B (50:50), C (70:30) and D (100:0) RPOo: RBD POo. The […]
This paper reviews past and recent work on at- mospheric concentrations of carbon dioxide (CO2)in and above stands of oil palm.Although data is limited, atmospheric CO2 concentrations both within and above stands,determined for several plantings,showed large diurnal variations with CO2accumulating to high levels over-night.Over much of the day, higher concentrations than are generally recognized as […]
There have been significant losses of biodiversity in the tropics at ecosystem, species and genetic levels as a consequence of agricultural development resulting in simplified landscapes with large areas dominated by crop monocultures. While it is suggested that many ecosystem services can be maintained by a few key species under present environmental conditions, particularly in […]
As both embryogenic and non-embryogenic calli were found to be distinctly different, this implies that their gene expression would be differentially regulated as well. Studies in other areas, in particular, medical research have used gene expression patterns to classify and predict the outcomes from specific conditions. This then led to a concerted effort to isolate […]
