Abstract

This work deals with the surface modification of Coir fibre through graft copolymerization process. Graft copolymerization of methyl methacrylate (MMA) onto coir fibre was carried out with Potassium per sulphate (PPS) as an initiator under the catalytic influence of Ferrous ammonium sulphate (FAS) in aqueous medium. Control and grafted coir fibres were subjected to evaluation of properties like tensile strength, flexural rigidity, density, water absorbance and light fastness studies. It was observed that MMA grafted coir fibre shows more resistance towards water and light fastness when compared with that of control coir fibre. Further morphological, structural changes and thermal stability of control and grafted coir fibre have also been studied by SEM and TGA techniques. For statistical significance the Analysis of variance (ANOVA) were studied and the P values obtained were less than 0.05 which revealed that the value was highly significant for the improvement of physical properties on coir fibre by graft Co- polymerization.

Abstract

The purpose of this research was to study processing of coconut oil which focused on evaluation of the quality of oil by using fruit of several Dwarf coconut as raw materials. The varieties used were Salak Green Dwarf (SGD), Raja Brown Dwarf (RBD) and Bali Yellow Dwarf (BYD). The oil was extracted through the wet process by heating technique. The coconut oil volume was measured and evaluated for its fatty acids profile, free fatty acid contents, moisture content, color, smell and taste. The by-products such as coconut residue and blondo were measured, too. The results showed that processing of oil from 200 Dwarf nuts produced 7.1-8.4 L. The highest volume of oil (8.4 L) was resulted from SGD. The oil was generally having high medium chain fatty acid around 58.50-62.32% including lauric acid at 46.82-48.46%. The oil made from fruits of SGD contained the highest lauric acid around 48.46%, followed by RBD and BYD reaching 48.06% and 46.82%, respectively. It had a good smell, and fatty acid and moisture content were in accord with Indonesian National Standard. The coconut oil processed using the fruit of the SGD and RBD has a clear white color, while the BYD having clear yellow in color, like corn oil.

Abstract

A member of the Aintegumenta sub-family of Apetala gene family encoding two APETALA2 (AP2) domains was isolated and termed as Cocos nucifera Aintegumenta like gene (CnANT). The deduced amino acid sequence of the conserved domains shared a high similarity with Aintegumenta-Like (ANT like) genes in Arabidopsis thaliana, Elaeis guineensis, Oryza sativa. Comparison of transcriptomes in different tissues revealed that CnANT transcripts were high in mature zygotic embryo (12 months after pollination; 12ME). Quantitative RT-PCR results confirmed the higher CnANT transcript accumulation in mature zygotic embryos while transcripts were rarely detected in vegetative tissues such as leaf. The expression data and global transcriptome data were therefore consistent across the embryo maturity stage and showed that CnANT could play a role in embryogenesis.

Abstract

The peculiar farm of coconut,” Dikiri” was studied for its kernel composition including pectin content with the objective of developing a jam out of Dikiri kernel. Three levels of Dikiri pulp, 20%, 30% and 40%, were evaluated to prepare Dikiri based jam. Two types of jam were prepared; Jam made with Dikiri only as the fruit pulp and the jam with Dikiri pulp together with 10% pineapple. They were tested for sensory attributes and were compared with pineapple jam prepared with added commercial high methoxyl pectin. The best jam was selected for shelf life study at room temperature. Results showed that Dikiri kernel differs from ordinary coconut for all the variables tested in proximate composition analysis. Dikiri kernel contained 16.6% of high methoxyl pectin on a dry weight basis. The jam with 30% Dikiri pulp was selected as the best total pulp ratio and the incorporation of 10% pineapple pulp into Dikiri gives better sensory properties compared with Dikiri only jam. In conclusion, there is a possibility of formulation of jam without adding external pectin with considerable sensory acceptability and good keeping quality.

Abstract

Characterization of conserved coconut germplasm has been undertaken globally for identification of important features of different accessions for them to be effectively used in coconut breeding. One hundred and fifty seven accessions comprising of local and exotic material have been conserved in ex-situ field genebanks of Coconut Research Institute in Sri Lanka. The objective of this study is to quantitatively characterize nut yield and fruit components by weights among Sri Lanka Tall (Typica) coconut accessions. Twenty local tall coconut accessions were characterized for nut yield and fruit components following Bioversity International descriptors for coconut. Bunch wise nut yield was recorded in all the coconut phenotypes in the six most mature bunches in 25 randomly selected palms from each accession. Sampled nuts were scored for weights of fresh nut, husked nut, split nut and kernel and the weights of husk, water and shell of each nut were derived from the scored data. Analysis of variance by general linear models procedure and mean separation by Duncan’s multiple range test were performed in SAS v8 and principal component analysis and cluster analysis using squared Euclidean distances were performed in Minitab V17. General linear models procedure revealed significant differences for nut yield and all the fruit components at 5% probability level. Walahapitiya recorded the highest average nut yield followed by the Razeena with statistically equal performances. Clovis recorded the highest values for most of the parameters for fruit component analysis followed by the accession Margaret, grouping together in Dendogram and the scatter plot. The highest per nut kernel producer, Clovis, was followed by Margaret with statistically equal performances and this is important because kernel is the main economically important component followed by the husk. Results revealed that there is no significant correlation between nut yield and all the fruit components in tall accessions indicating the importance of taking these two parameters separately to formulate germplasm conservation strategies.

Abstract

Coconut (Cocos nucifera) is an important economic crop in Sri Lanka; one of the world's largest exporters of coir fiber and coir products. Ceratocystis paradoxa is a pathogen causing stem bleeding, leaf and fruit rot in variety of crop plants including coconut. Since C. paradoxa is associated with coconut trees, there is an opportunity for the pathogen exist in coir and coir products as well. According to the quarantine requirements, this pathogen has to be free in coir and coir products that are exported from Sri Lanka. During this study the pathogen was isolated from the samples of coir collected from different locations in North Western Province and Western Province of Sri Lanka. Colony morphology and spore morphology were compared among these isolates. Bio-control and the sensitivity of the isolates to the antagonist were evaluated against Trichoderma viride. According to the results the pathogen was present in all the samples collected from different locations of the coconut growing triangle. The isolated colonies grown on Potato Dextrose Agar (PDA) plates were white in early stage but became black, one or two days later. The growing colonies produced two asexual spores; the endoconidia and chlamydospores. Endoconidia are formed in the conidiophores making long chains. They are thin-walled cylindrical 9-12 µm x 4.8-7.2 µm in size, yet two isolated from North Western Province had a smaller width of 2.4 µm endoconidia. Chlamydospores are thick walled formed in short chains, dark color, and are mostly oval shaped, 9.6-16.8µm x 7.2-9.6µm in size, yet one isolated from North Western Province had a width of 4.8 µm. The chlamydospores are varied in morphology according to the geographical distribution of the pathogen. The variability of chlamydospore morphology predicts the genomic variability among the isolates. Biological control of C. paradoxa using T. viride was successful in all the isolates used in vitro studies. The experiments showed similar effects of T. viride on all C. paradoxa isolates as the biological control agent by killing the vegetative growth and losing the spore viability.
