whole-plant adjustments in coconut (cocos nucifera) in response to sink-source imbalance.coconut (cocos nucifera l.) is a perennial tropical monocotyledon that produces fruit continuously. the physiological function of the large amounts of sucrose stored in coconut stems is unknown. to test the hypothesis that reserve storage and mobilization enable the crop to adjust to variable sink-source relationships at the scale of the whole plant, we investigated the dynamics of dry matter production, yield and yield components, and concentrations of nonstructural carbohydrate reserves in a c ...200818519251
antiulcerogenic effects of coconut (cocos nucifera) extract in rats.a warm water crude extract of coconut milk and a coconut water dispersion were investigated for their antiulcerogenic effects in male wistar albino rats. ulcers were induced in the male rats by subcutaneous administration of indomethacin (40 mg/kg) using standard procedures. the ulcer inhibition rate (uir) was taken as a measure of the cytoprotection offered by test substances. coconut milk (2 ml daily oral feeding) produced a stronger percentage (54%) reduction in the mean ulcer area than cocon ...200818521965
correlation between the distribution of lignin and pectin and distribution of sorbed metal ions (lead and zinc) on coir (cocos nucifera l.).plant fibres are capacious for sorption of metal ions, and can be used in water cleaning. knowledge about the sorption will help in selection of the fibre and optimisation of its chemical modification, if any. the aim of this paper is to investigate the connection, if any, between the distribution of lignin and pectin and the loading of pb and zn on coir (mesocarp fibres from cocos nucifera l.). the coir consisted mainly of xylem and a fibre sheath. the lignin was evenly distributed in the cell ...200818558484
analysis of monoglycerides, diglycerides, sterols, and free fatty acids in coconut (cocos nucifera l.) oil by 31p nmr spectroscopy.phosphorus-31 nuclear magnetic resonance spectroscopy ( (31)p nmr) was used to differentiate virgin coconut oil (vco) from refined, bleached, deodorized coconut oil (rco). monoglycerides (mgs), diglycerides (dgs), sterols, and free fatty acids (ffas) in vco and rco were converted into dioxaphospholane derivatives and analyzed by (31)p nmr. on the average, 1-mg was found to be higher in vco (0.027%) than rco (0.019%). 2-mg was not detected in any of the samples down to a detection limit of 0.014% ...200818576656
sex ratio and female sexual status of the coconut pest, oryctes monoceros (coleoptera: dynastidae), differ in feeding galleries and pheromone-baited traps.oryctes monoceros is a serious coconut pest, causing up to 40% damage in tropical africa. synthetic aggregation pheromone, ethyl 4-methyloctanoate, has been used to lure adults to traps. traps with pheromone plus decaying palm material captured a high proportion of males. this raises the question whether individuals, which damage palms are receptive to the pheromone. we studied the sex ratio of the insects feeding on coconuts and those attracted to pheromone traps. sixty two percent of adults fr ...200818662429

stomach nematodes (mastophorus muris) in rats (rattus rattus) are associated with coconut (cocos nucifera) habitat at palmyra atoll.black rats ( rattus rattus ) and their stomach nematodes (mastophorus muris) were historically introduced to islets at palmyra atoll in the central pacific line islands. to investigate patterns of parasitism, we trapped rats and quantified nematodes on 13 islets of various sizes and habitat types. most rats were parasitized (59%) with an average of 12 worms per infected rat. islet size did not greatly influence parasite population biology. nematodes also did not appear to affect rat condition (w ...201019799487
phylogenetic analysis of seven wrky genes across the palm subtribe attaleinae (arecaceae) [corrected] identifies syagrus as sister group of the coconut.the cocoseae is one of 13 tribes of arecaceae subfam. arecoideae, and contains a number of palms with significant economic importance, including the monotypic and pantropical cocos nucifera l., the coconut, the origins of which have been one of the "abominable mysteries" of palm systematics for decades. previous studies with predominantly plastid genes weakly supported american ancestry for the coconut but ambiguous sister relationships. in this paper, we use multiple single copy nuclear loci to ...200919806212
