Ganoderma boninense has been identified as a ‘white rot’ pathogen that causes basal stem rot (BSR) disease in oil palm. In spite of numerous reports on the severity of BSR and its effect on the oil palm industry, no single treatment has effectively tackled the problem. Most control measures have to date continued to give […]
Screening for natural haploids by flow cytometry and chromosome counts on 518 culled tissue culture plantlets and 13 twin germinated seeds yielded no haploids. In anther culture experiments, anthers bearing pollen mother cells (PMC) at the uninucleate and tetrad stages were collected and stored at 4oC for one, two, four, six, eight, 10 and 12 […]
Safety and efficacy evaluation of the active ingredients or the cosmetic products themselves is important to ensure customer safety, and to substantiate claims. As newly synthesized or extracted ingredients become available in the cosmetics and personal care industry, new cosmetics are continually being formulated to capture new market segments. The rapid development of new actives […]
Physiological plant stress, particularly water stress, is discussed in this article. Observations made on oil palm seedlings and in the field are included. Assessment of plant water status was done through observations for stress symptoms and measurements on canopy temperature. Physiological responses of oil palm under different soil conditions, seasonal drought and different planting materials […]
In recent years, pheromone trapping has been employed in many pest management programmes worldwide. Pheromone trapping can assist decision making in integrated pest management (IPM) programmes. Considerable improvements have been made in the identification and formulation of blends of pheromones for the management of agricultural insect pests. The progress and prospects of using pheromone for […]
Application of P fertiliser is essential to achieve optimal oil palm yield production throughout Sumatra. Two trials were carried out in Sumatra, one in the north on a typical acid volcanic soil dominated by rhyolite and the other in the south on a representative acid volcanic/sedimentary soil dominated by dacite, to determine the most suitable P fertiliser type in these locations. The trials […]
Recurrent cycles of inbreeding (self or sib crosses) have been commonly used in conventional breeding to produce highly homozygous lines in a range of crop species. Thirty-two Simple Sequence Repeat (SSR) markers were involved in assessing the homozygosity of 23 oil palm Single Seed Descent (SSD) programmes which involved 509 parents. From the complete genotype […]
In South America, factorial fertilisation trials were set up on oil palm estates managed by Palmeras de los Andes in Ecuador and Indupalma S.A. In Colombia to control fertilisation during the two oil palm crop cycles. These experiments were designed to determine the optimal leaf contents of N, P, K, Mg and Cl, in recent […]
Sulphur (S) has received limited attention by researchers, agronomists and planters involved in oil palm cultivation, despite the fact that the requirement at tissue level – as indicated by published critical concentrations in Frond #17 – is the same for S and magnesium (Mg) (0.2%). The continuous trend toward S-free fertilisers (urea, rock phosphate, KCl, […]
A genetic diversity analysis was performed on 2039 dura seed palms and 25 pisifera pollen parents using eight Simple Sequence Repeat (SSR) markers. The heterozygosity of the pisifera germplasm (mostly AVROS) was higher than the Deli dura seed palms. Variation was found in heterozygosity among the Deli dura progenies, selected for seed production. As expected, […]
