| Performance evaluations of three coconut cracking devices was carried out and its results compared with the conventional (hand cracking technique) of hitting on hard surface. The three devices include a punch-split device, an impact-split device and hydraulic press split device which were developed at the Department of Agricultural & Bioenvironmental Engineering Technology, Federal College of Agriculture, Ishiagu. Each technique was evaluated for output capacity, cracking efficiency, ergonomics, and time required to crack a unit of different grades of coconut. The average cracking efficiency for punch split was 87.09 per cent with a range of 86.76 to 95.00 per cent, impact split efficiency varied from 83.33 to 95.00 per cent with the average of... |

| ABSTRACTStem bleeding disease (resinosis) of coconut palm is caused by Thielaviopsis paradoxa and is very important in the state of Sergipe, Brazil. Understanding the epidemiological behavior of the disease is essential for establishing more efficient control strategies. Thus, we characterized the temporal progression and spatial distribution of stem bleeding in a commercial orchard under conditions of natural infection in the area of Neopolis, Sergipe. Three plots with 729 plants each were selected and evaluated every two months for stem bleeding incidence. In the temporal analysis, the monomolecular model gave the best fit to data on disease incidence, as it accurately showed the temporal dynamics of the disease during the experiment period. The spatial... |

| ABSTRACT The oxidative stability of linseed (L), cotton (A), and coconut (C) oils, as well as of linseed:cotton (LA), linseed:coconut (LC), and linseed:cotton:coconut (LAC) compound oils was evaluated under accelerated storage at 60°C/20 days. Coconut oil showed to be rather stable, mainly due to low levels of peroxides, conjugated dienes, ρ-anisidine, and long induction period. In addition, along with cotton oil, it improved the stability of linseed oil in the formulation of LAC compound oil. As to fatty acid profile, the compound oils showed to be composed mainly by unsaturated fatty acids. Cotton and coconut oils presented higher retention of total phytosterols, 78.87 and 76.16%, respectively, after 20 days of storage, when compared to linseed oil. The... |

| Abstract Owing to the high content of lignocellulose, desiccated coconut become a healthy material for dietary fiber supplementation. In this study, the changes in solubility of the fibers of desiccated coconut were evaluated. The changes of the pHs and weight losses were studied. Furthermore, variations of the ingredient structures of desiccated coconut by hydrolysis by hydrochloric acid were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). After hydrolysis 30 s, the pHs of all systems increased, while six hours later, the pH of only system with initial pH = 1.00 decreased. The decline of pH only existed in hydrolysis systems with initial pH = 1.00, there is no relevant with... |

| Coconut palms of the Tall group were introduced to Brazil from the Cape Verde Islands in 1553. The present study sought to evaluate the genetic diversity among and within Brazilian Tall coconut populations. Samples were collected of 195 trees from 10 populations. Genetic diversity was accessed by investigating 13 simple sequence repeats (SSR) loci. This provided a total of 68 alleles, ranging from 2 to 13 alleles per locus, with an average of 5.23. The mean values of gene diversity (He) and observed heterozygosity (Ho) were 0.459 and 0.443, respectively. The genetic differentiation among populations was estimated at θ = 0.1600 and the estimated apparent outcrossing rate was t a = 0.92. Estimates of genetic distances between the populations varied from... |

| O coqueiro é constituído de uma só espécie (Cocos nucifera L.) e de duas variedades principais, a gigante (Typica) e a anã (Nana). É a palmeira mais amplamente distribuída e extensivamente cultivada, além de ser uma das mais importantes espécies tropicais utilizadas pelo homem. Marcadores baseados em DNA têm sido indicados como os mais adequados nos estudos de diversidade genética em coco e os marcadores microssatélites (SSR) têm se mostrado como ferramenta poderosa em análises de estrutura de populações. O objetivo do presente trabalho foi avaliar a diversidade genética em dez populações de coqueiro-gigante-do-Brasil por meio de 13 marcadores microssatélites (SSR). A diversidade genética medida em 195 indivíduos de dez populações de coqueiro gigante do... |
