Modelling the effects of physiological and morphological characters on oil palm growth and productivity
The model OPRODSIM is a mechanistic simulation model of oil palm growth and yield, the output of which depends crucially on the values assigned to various physiological and morphological characters. In this article, the effects of manipulating these values are explored and related to what is known concerning the magnitude of their natural variation. The […]
Modelling oil palm yield based on source and sink
Although fruit bunch production by oil palm is often considered to be mostly dependent upon the ability of the plant to produce assimilates, the availability of an adequate sink is also of importance in optimizing yield. The model OPRODSIM initially simulated yield based on the assimilates remaining after the requirements of vegetative growth had been […]
Pesticide application in the oil palm plantation
This article attempts to give an overview of the combined practice of pesticide management in oil palm plantations, the types of pesticides commonly used and the method of analysis to determine pesticide residues in palm oil. A brief outline of the regulatory controls for pesticides is also included. Artikel ini memberi suatu peninjauan umum tentang […]
Biomarkers: finding a niche in oil palm tissue culture. Part 2 – targeting the transcriptome
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 […]
Biodiversity, agricultural development and valuation of ecosystem services
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 […]
Modeling oil palm bunch components, palm oil and kernel yields
The source-based model OPRODSIM (Oil Palm Production Simulator) simulates fresh fruit bunch (FFB) yield based on the assimilate remaining after the requirements of vegetative growth have been met. However, in its initial form it does not take account of pollination as a factor limiting yield, nor does it provide an estimate of palm mesocarp oil […]
Improving the efficiency of oil palm tissue culture
Planting clones seems to be the best approach to higher yield. Although the oil palm has been cloned for some years now, the production is still vastly below demand due to inefficiency at some of the cloning stages. This article describes some technologies developed by MPOB to improve oil palm cloning – liquid culture, efficient […]
A review on seed dormancy and germination
An overview of seed dormancy and germination in plants is presented with reference to various crops, especially oil palm, and the effects of plant growth regulators (PGRs) and chemicals are also highlighted. This review also includes the biochemistry and molecular studies in seed germination, and related issues. Rumusan keseluruhan bagi kedorminan biji dan pencambahan dalam […]
