quantification of seed oil from species with varying oil content using supercritical fluid extraction.the quantity and composition of seed oil affects seed viability and storability and hence the value of a species as a resource for nutrition and plant conservation. supercritical fluid extraction with carbon dioxide (sfe-co2) offers a rapid, environmentally friendly alternative to traditional solvent extraction.200818473329
host response of ornamental palms to rotylenchulus reniformis.the responses of 20 species of ornamental palms and one cycad (cycas revoluta) to two populations of the reniform nematode, rotylenchulus reniformis, from southern florida were studied in two greenhouse experiments conducted in 1989-1991 and 1991-92. ornamental palms in pots were exposed to initial population densities of 400 and 1,500 r. reniformis/l00 cm(3) soil for 16 and 15 months, respectively. nematode reproduction occurred on acoelorrhaphe wrightii and washingtonia robusta, but not on the ...199419279956
evaluation of an oil dispersion formulation of imidacloprid as a drench against rhynchophorus ferrugineus (coleoptera, curculionidae) in young palm trees.background: the red palm weevil, rhynchophorus ferrugineus (olivier), is a phytophagous insect that feeds on soft succulent tissues of most palm species and is considered the main palm pest in the middle east and the mediterranean basin. the aim of this study was to test the efficacy of imidacloprid oil dispersion (od) as a drench in preventive and curative treatments against r. ferrugineus in phoenix canariensis, washingtonia robusta, washingtonia filifera and trachycarpus fortunei. results: le ...201122262504
