Publisher : International Coconut Community

Knowing the magnitude of therapeutic plants such as Micrococca mercurialis (MM), Abutilon palmeri (AP) and Callistemon citrinus (CC), we also planned to extend our research work on Cocusnucifera fibers (CF) and dust (CD) as it has copious medicinal properties. The current study deals with the green synthesis of silver nanoparticles (AgNPs) from fresh aqueous extracts and AgNO3 solution. The biogenic conversion of silver ion to silver is relatively expeditious at two different time intervals and pH. The isolated silver nanoparticles (AgNPs) from the bio extracts were identified initially by scrutinizing the colour variations. The biosynthesized AgNPs were characterized by UV, XRD, Laser Diffraction Particle size Analyser, fluorescence spectroscopy, SEM and TEM. UV absorbance at 435-460nm for silver nanoparticles was observed for the above extracts. The XRD pattern of all extracts showed the distinctive Bragg peaks of face centre cubic (fcc) crystalline system available in nature. SEM and TEM analysis of the silver nanoparticles indicated that the particle size was in the range of 2-100nm with polygonal and spherical shapes. The biosynthesized AgNPs were evaluated for antimicrobial activities. The CFAgNPs showed an efficient antibacterial activity at lower concentration (25mg/ml) against Pseudomonas demolytica followed by Staphylococcus aureus and Escherichia coli. Similarly all plant extracts have better activity against fungal strains. It is concluded that the biogenic blend of AgNPs is simple, extremely rapid, beneficial, eco-friendly and more stable without any toxic effects. Of these, CFAgNps may be used for the preparation of antibacterial groupings against Pseudomonas demolytica and Staphylococcus aureus.

Breeding programs of kopyor dwarf coconut require a population base with high genetic diversity especially for characters that relate to fruit production. The study aims to determine the appearance of three kopyor dwarf coconuts from Pati District and correlations among 13 characters of Kopyor Green Dwarf, Kopyor brown dwarf, and Kopyor Yellow Dwarf and to study twelve vegetative and generative characters which directly and indirectly affect the number of fruits. The study was conducted at The Paniki Experimental Garden, North Sulawesi, Indonesia from August 2015 to February 2016. The design used was randomized block design with three treatments and three replications. Observed thirteen characters including number of bunches (NB), number of fruit (NF), number of leaves (NL), number of leaflets (NLL), width of leaflets (WLL), length of the leafleats (LLL), length of petiole (LP), width of petiole (WP), thick of petiole (TP), length of rachis (LR), length of leaf (LL), height of stem (HS), and girth of stem (GS). Path analysis among morphological characters to number of fruits was worked out using the formula of Singh and Chaudary. Results of variance analysis showed Kopyor Green Dwarf and Kopyor Brown Dwarf significantly differed from Kopyor Yellow Dwarf. Results of simple correlation analysis found no correlation among twelve characters with number of fruits for the three kopyor dwarf coconut, but the results of the path analysis of characters NL (r=0.5627), NLL (r=0.5920), HS (r=0.4861), and GS (r=0.6123) for the Kopyor Green Dwarf; NB (r=0.4241), LP (r =0.6390) , WP (r = 0.8705), LR (r = 0.5235), and LL (r = 0.6257) for the Kopyor Brown Dwarf; and WLL (r = 0.8413), LLL (r = 0.5617), TP (r = 0.5864), LR (r =1.5795), and LL (r = 1.0228) for the Kopyor Yellow Dwarf directly affect the number of fruits. These characters can be used for basic selection in breeding of kopyor coconut.

Aquatic weeds cause severe productivity loss in agriculture. These plants invade lakes, ponds, rivers, canals and agricultural fields, becoming noxious weeds. The study was conducted at the vermicomposting unit of the Coconut Research Institute, Lunuwila, in the Low country Dry Zone of North Western province of Sri Lanka from August 2012 to May 2013 to find out the feasibility of producing vermicompost from three aquatic weeds; Salvinia molesta, Eichhornia crassipes and Lagenandra toxicaria. Vermicompost and compost were prepared separately from aquatic weeds and Gliricidia and Guinea grass combinations. During the vermicomposting process, growth parameters of earthworms; number of earthworms, was taken in every ten days interval further, physical, chemical and biological properties of compost and vermicompost were analyzed. Experiment was carried out in a Complete Randomized Design (CRD) with eight treatment and five replicates in each treatment. Eichhornia and Salvinia recorded the highest adult earthworm number and juvenile number with the lowest mortality rate. Electrical conductivity (6.75 dSm-1), organic carbon (13.21%), phosphorous (3.61%), potassium (5.03%) and calcium (6.12%) were significantly high in Lagenandra toxicaria, Gliricidia and Guinea grass treatment was significantly high in nitrogen content (3.93%) and low in C: N ratio (2.51), compared to aquatic weeds. Salvinia showed comparatively higher nitrogen content and lower C: N ratio among aquatic weeds. Both Eichhornia and Lagenandra showed significantly higher microbial activity. Vermicompost was superior in all the properties compared to compost in the same substrate. The study revealed that aquatic weeds such as Salvinia molesta, Eichhornia crassipes and Lagenandra toxicaria which are readily available in the coconut triangle can be successfully used to produce Vermicompost. It can be concluded that the Vermicompost produced from aquatic weeds locally could be a suitable organic fertilizer for organic coconut farming in Sri Lanka.

A comparison is made on the effect of organic and inorganic fertilizers on the some morphological characters of coconut. The study demonstrated that the treatments T1 {Nitrogen, Phosphorus and Muriate of potash (NPK) + Neem seed powder (NSP) + Gliricidiasepium leaves (GSL)} and T2 (NPK+ GSL) significantly increased most of the morphological characters (stem girth, number of leaves, petiole and leaflets). The study revealed that vegetatively the coconut was grown well on soil amended with organic and inorganic fertilizers. The morphological characters i.e the stem girth (173.77 cm) of coconut at 20 cm height T1 (NPK + NSP + GSL) treatment produced maximum girth as compared to T2 to T8 {T2 (NPK+ NSP), T3 (NPK+ GSL), T4 (NSP + GSL), T5 (NPK), T6 (GSL), T7 (NSP), T8 (Control)} treatments. The 11 leaf scars length (80.44 cm) was significantly (p<0.05) highest in T1 as compared to T3 to T8 treatments. The present study also revealed that the number of leaves (28.77) were significantly (p<0.05) greater in T1 as compared to T5 to T8 treatments. The petiole length (139.44 cm) and thickness (3.27 cm), were found significantly (p<0.05) highest in T1 as compared to T8 treatment. Leaflets length and number of leaflets were significantly high in T1 and T2 as compared to T3 to T8 treatments while, the leaflets width (5.04 cm) was significantly high in T1 as compared to other treatments. It is therefore, recommended that treatment T1 {NPK (1.0:0.5:1.0kg) + NSP (10.0kg) + GSL (20.0kg)}/palm/year was enough to improve the morphological characters to enhance future productivity.

Coconut is one of the most important small holder crops worldwide. Conservation of coconut as seeds or field gene banks is not effective due to a range of limitations. Cryopreservation, which is the conservation of living propagules at very low temperature (-196ºC), is the only method available currently for the long-term conservation of germplasm for problem plant species such as recalcitrant and vegetatively propagated plant species. This review summarizes different cryopreservation techniques that have been published from 1984 until the present in relation to different coconut material; it includes a brief discussion about short and medium-term cryopreservation before describing long-term preservation. It discusses factors affecting the process and success of cryopreservation, such as selection of plant material, pre-culture of tissues, osmoprotection, dehydration, cryo-storage, thawing and post-culturing of tissues, and finally to plants. The review also describes histological and ultra-structural studies on and the use of molecular markers to assess genetic stability after cryopreservation. Limitations and future directions related to coconut cryopreservation are discussed. Additional experiments are identified that will need to be undertaken to improve our understanding of the different cryopreservation methods.

The aim of the study is to formulate sports drinks using fruit juices and tender coconut water and to test their organoleptic acceptability. Sports drinks were developed using sweet lime juice (F1), lime juice (F2), pineapple juice (F3) and tender coconut water (F4) blended with honey, salt and water. The prepared sports drinks were calculated for their nutrient content and organoleptically evaluated using a 5 point hedonic scale. The energy content of F4 was the highest (68.3 Kcal/100 ml), followed by F1 (65.35 Kcal/100 ml) and F3 had the lowest value of 54.9 Kcal/100 ml. The iron content of F3 was the highest (1.2 mg %). The amount of sodium and potassium of F1 was high (237.1 and 245.78 mg %) and almost equal in quantity. The sodium content of F3 was highest (301.05 mg %) followed by F4 (289.6 mg %) and F2 (473.8 mg %). The potassium content of F3 was the least (47.38 mg %), while that of F2 and F4 was 140.19 mg % and 128.69 mg % respectively. The mean scores obtained for overall acceptability was 3.5±0.7, 3.1±0.7, 4.2±0.6 and 4.6±0.5 for F1, F2, F3, F4 respectively. F3 and F4 obtained a mean score of more than 4.0 for taste and overall acceptability. Results of ANOVA indicate no significant difference for colour, appearance and flavour (p≥0.05) between the four variants whereas it was significant for texture, taste and overall acceptability (p≤0.05). The formulated sports drinks contribute to the nutrient requirement of the athletes. On comparing the costs of all the formulated sports drinks, F4 (sports drink made from tender coconut water) was found to be more cost effective and had less food wastage. It may be concluded that sports drink prepared with tender coconut water (F4) being highly acceptable and cost effective can be recommended for athletes for optimal performance.

Publisher : International Coconut Community

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.

Publisher : International Coconut Community

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.

Expression of Aintegumenta-like Gene Related to Embryogenic Competence in Coconut Confirmed by 454-pyrosequencing Transcriptome Analysis Bandupriya, H. D. D.
International Coconut Community Journal Vol 31 No 2 (2015): CORD
Publisher : International Coconut Community

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.

Publisher : International Coconut Community

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.
