Provedor de dados: 14
Autores: SILVA, C. M. M. de S.
Foram avaliadas no Banco Ativo de Germoplasma de Forrageiras do Centro de Pesquisa Agropecuaria do Tropico Semi-Arido- CPATSA da EMBRAPA, oito cultivares de leucena de diferentes procedencias. Foram avaliados com relacao a producao da materia seca, na fracao comestivel, digestibilidade in vitro da materia seca, para diferentes cultivares. A composicao mineral da fracao comestivel de leucena, para macro e micronutrientes. A leucena, na zona semi-arida de Pernambuco, pode proporcionar um suplemento forrageiro de alta qualidade.

Provedor de dados: 14
Autores: LEITE, G. G.; SILVEIRA, L. F. da; FERNANDES, F. D.; GOMES, A. C.
O trabalho foi realizado em uma area de baixada, com solo Gleissolo haplico no Colegio Agricola de Brasília-DF, no periodo de outubro de 1998 a fevereiro de 1999. Foram avaliados o crescimento, o vigor da rebrotacao e a composicao quimica do capim Paspalum atratum cv. Pojuca aos 14, 21, 28, 35, 42, 49 e 56 dias de idade, em tres periodos de crescimento (C1, C2, C3), defasados de sete dias. Utilizou-se o delineamento experimental de blocos ao acaso com parcelas subdivididas com tres repeticoes. Aplicou-se a analise de variancia com regressao para analisar os efeitos de idade e, o teste de Tukey para estudar os efeitos de crescimento. A graminea apresentou padrao de desenvolvimento linear ao longo da estacao de crescimento. O vigor de rebrotacao nos...

Physical and thermal properties of mud-dominant sediment from the Joetsu Basin in the eastern margin of the Japan Sea

Physical properties (bulk density and porosity) and thermal properties (thermal conductivity, heat capacity, specific heat, and thermal diffusivity) of sediment are crucial parameters for basin modeling. We measured these physical and thermal properties for mud-dominant sediment recovered from the Joetsu Basin, in the eastern margin of the Japan Sea. To determine thermal conductivity, heat capacity, and thermal diffusivity, the dual-needle probe method was applied. Grain density and grain thermal properties for the mud-dominant sediment were estimated from the measured physical and thermal properties by applying existing models of physical and thermal properties of sediment. We suggest that the grain density, grain thermal conductivity, and grain thermal...

Estudio composicional de las arenas ferrotitaníferas del sector comprendido entre el Estero Data de Posorja y el Monasterio de Santa Teresa, Provincia del Guayas, Ecuador
Provedor de dados: 20
Autores: Soledispa, B.; Villacres, J.
En el presente artículo se trata de remarcar las características mineralógicas y la génesis de este tipo de arena en un sector de Playa situada en la zona costera de la provincia del Guayas. Se pretende con este estudio:-Establecer las condiciones y mecanismos que favorecieron la acumulación de las arenas ferrotitaníferas en las playas, así como su potencial económico y su probable extensión a la zona sumergida. -Estudiar estos minerales detríticos pesados, como posible fuente para la obtención de hierro y titanio. -Iniciar el inventario de estos depósitos a nivel nacional.

INFLUENCE OF CITRUS LEPROSIS ON THE MINERAL COMPOSITION OF Citrus sinensis LEAVES
Provedor de dados: 63
Autores: Nogueira,N. de L.; Rodrigues,J.C.V.; Cabral,C.P.; Prates,H.S.
Citrus leprosis is the main viral disease affecting citrus in Brazil. Viral diseases can affect the mineral composition of citrus leaves, inducing mineral deficiencies. The aim of this work was to verify the influence of citrus leprosis on the mineral composition of citrus leaves, cultivar Pera. Orange seedlings were grown in pots containing sterile soil, and kept under greenhouse conditions. When plants had 15 to 20 leaves, they were infested with the mite Brevipalpus phoenicis, the leprosis vector, collected from infected citrus plants. Other plants were not infested, and were used as the control. Ninety days after infestation, all the infested plants presented leprosis lesions. The six upper leaves of each plant were collected and the determination of...

Biochemical characterization and antioxidant activity of walnut kernel (Juglans regia L.) of accessions from Middle and High Atlas in Morocco
Provedor de dados: 3
Autores: Kabiri, Ghizlane; Bouda, Said; Elhansali, Mohammed; Haddioui , Abdelmajid.
Biochemical composition and antioxidant activity were determined in kernel nuts for eleven Moroccan walnut (Juglans regia L.) accessions representing its main cropping area. Total oil, carbohydrates, crude protein, energy value, crude fiber and flavonoid have varied significantly between accessions, respectively within the range values of 54.50-65.48%, 8.17-19.25%, 11.5-25.58%, 648.91-713.83 Kcal, 4.17-6.75% and 12.59-62.11mg RE 100 g-1 DM.&amp;nbsp; Besides, mineral composition (mg 100 g-1) of kernel have varied also significantly among accessions and particularly for phosphorus (338.1-675.87), copper (2.08-6.67), zinc (3.39-18.63), iron (1.17-2.64), chromium (0.16-0.20), nickel (1.26-1.45) and boron (0.07-1.49). However, dry matter (96.75-98.56%),...

This study was carried out to determine, evaluation and characterization of the morphological, physiological as well as mineral nutrient vitiations among all forty five purslane accessions collected from different locations of West Peninsular, Malaysia. Significant differences (p&lt;0.05) were observed for all those traits measured regarding morphological, physiological and mineral composition. Morphological traits viz. plant height varied between 20.06-40.8 cm; number of main branch, 1.4-4.4; number of nodes, 8.4-31; internode distance, 2.1-3.43 cm; stem diameter, 2.12-3.8 mm; number of leaves, 97-1019; leaf area, 1.03-2.21 cm², number of flowers, 14-826.8; root length, 5.09-11.7 cm; fresh weight, 40-280 g; and dry weight varied between 2.71-29.16 g....
