The Role of Boron in the Oil-palm (Elaeis guineensis)

ABSTRACTMolecular genetic analysis of hard bunch phenomenon in oil palm was done in order to elucidate the role of genetic factor underlying hard bunch in oil palm plantation. The aim of this study was to identify the AFLP primer combination that co-segregates with hard bunch phenotype related gene in oil palm. Molecular analysis was done by bulk segregant analysis approach. DNA was isolated from leaves of the normal and hard bunch palm. DNA from ten individual palms from each category were pooled and used as a template. A total of 56 AFLP primer combinations were selected for selection of polymorphic primer, and as a result it was found that 22 AFLP primer combinations (39.28%) were polymorphic. A total of 48 individual of palm DNA containing 24 individual for each group were further genotyped by those 22 polymorphic markers. Of these, one AFLP primer combination (E-ACC/M-CTG) was obtained as a co-segregated marker that distinguished the hard bunch DNA from the normal one. Based on the analysis of the target sequence aligned to the oil palm DNA sequences available in database, we found that our sequence has similarity with Ty-1 copia retrotransposon. This sequence distribute in all 16 linkage group of oil palm genome.Keywords: abnormal fruits, AFLP, oil palm, Ty-1 copia retrotransposon

African Oil Palm

Monocultures of the African oil palm (Elaeis guineensis) were studied between 2006 and 2013 so as to determine which species of snakes frequented them and to estimate the abundances of each species encountered. Thirty five species of snakes (three boas, one coral, 27 colubrids, one tropidophid, one typhlopid, and two vipers) were captured within palmeras. Palm plantations are revealed to (1) augment the densities of ten species of snakes well beyond the densities found by collectors in natural and/or relatively transformed habitats and (2) to not offer benefits to at least 75% of the snake community found in the vicinities of palm plantations. The majority of snake species (60%) found in palmeras are nocturnal species. The most common species (defined by having 15 or more captures) were Atractus univittatus, Bothrops asper, B. atrox, Epicrates maurus, Leptodeira annulata, Liophis melanotus, Ninia atrata, Oxyrhopus petolarius, Pseudoboa neuwiedii, and Tantilla melanocephala. Palm plantations permit substantial local population sizes for a fraction (< 25%) of the local snake community. Internal practices of such plantations could be modified so as to protect a larger share of the fauna by means of two practices: (1) construction and maintenance of paleras as well as (2) creating a mosaic of palm plantations enclosing “islands” of secondary forests.

Hybrid Embryo

Oil palm OG hybrid genetic potentials are high in term of vegetative and generative traits, such as: low height increment, compact palm, high free fatty acid and high carotenes. However, OG hybrid reproduction is hindered due to its low germination rate. So, alternative method for germination is needed, which is in vitro embryo zygotic culture. This study objective was to reveal the best medium composition for OG hybrid embryo culture by modificated several oil palm basic medium from oil palm tissue culture protocol and to understand the role of plant growth regulators, activated charcoal, and sucrose on in vitro growth and development of OG hybrid embryo. The design used was Completely Randomized Design (CRD) with 16 replication and 4 embryos for each replicates, while the treatments were: A1 = M129 (control); A2 = M129 + activated charcoal; A3 = M129+ activated charcoal + sucrose; A4 = ½ M129 + activated charcoal + sucrose; A5 = M129 + GA3 ; and A6 = M129 + GA3 + NAA. From the study we found that the best medium for OG hybrid open pollinated clone's embryo culture was M129 with GA3 and NAA (A6). This medium gave percentage of in vitro germination up to 14.06%, and later on the plantlets from this medium gave the best vegetative growth performance such as high number of leaves and primer roots.

Elaeidobius Kamerunicus

Abstract Oil palm (Elaeis guineensis Jacq) is an economically important crop in South-east Asia, especially in Malaysia and Indonesia. In Malaysia, oil palm is the most profitable commodity in the agriculture sector. The future of oil palm lies in obtaining a higher yield that is aligned and directed towards achieving the Sustainable Development Goals (SDG) by 2030. Elaeidobius kamerunicus was introduced into Malaysia during the late 1980s to boost the production of oil palm fruit bunches. Almost 40 years since the introduction of E. kamerunicus, significant improvements have been witnessed in the increase of oil palm yield. Nevertheless, the current concern in the oil palm sector is regarding the decreasing of fruit set that may be affected by E. kamerunicus. The weevil population plays a crucial factor in the pollination of oil palm. Several factors had been reported to reduce the weevil population such as natural enemies, interaction with local insects, pesticides, climate and male inflorescence. These factors have been addressed in this article based on various studies conducted since the first investigation in Cameroon by Syed in 1977. The role of the pollinator in terms of its biology, behaviour and pollination mechanism is also described in this article, together with the population management of the weevils. This review article will provide a summary of the current state of Elaeidobius kamerunicus in Malaysia and other neighbouring oil palm-producing countries.
