Nitrogen assimilation in Citrus based on CitEST data mining
(Sociedade Brasileira de Genética, 2007-01-01)
Assimilation of nitrate and ammonium are vital procedures for plant development and growth. From these primary paths of inorganic nitrogen assimilation, this metabolism integrates diverse paths for biosynthesis of ...
Effects of soil water deficit and nitrogen nutrition on water relations and photosynthesis of pot-grown Coffea canephora Pierre
(2002-12-01)
Coffea canephora plants (clone INCAPER-99) were submitted to low N (LN) or high N (HN) applications and two watering regimes (daily irrigation and irrigation every 5 days for a month). Although water potential was not ...
The dietary regime of detritivorous fish from the River Jacaré Pepira, Brazil
(1999-04-01)
The diet of detritivorous fish was analysed at four distinct habitats in a tropical river during the wet and dry seasons. Two methodologies were used to determine the diet of the fish: (1) the direct analysis of the stomach ...
Seasonal variation in leaf traits between congeneric savanna and forest trees in Central Brazil: Implications for forest expansion into savanna
(2013-08-01)
The ecology of forest and savanna trees species will largely determine the structure and dynamics of the forest-savanna boundaries, but little is known about the constraints to leaf trait variation imposed by selective ...
Fotossíntese, reservas orgânicas e rebrota do capim-mombaça (Panicum maximum Jacq.) sob diferentes intensidades de desfolha do perfilho principal
(Sociedade Brasileira de Zootecnia, 2002-11-01)
Buscando-se avaliar morfofisiologicamente a rebrota do capim-mombaça, quatro desfolhas foram impostas ao perfilho principal, sendo estudado o comportamento da planta em termos da taxa de expansão da área foliar, crescimento ...
Seasonal changes in vegetative growth and photosynthesis of Arabica coffee trees
(Elsevier B.V., 2004-10-08)
Seasonal changes in vegetative growth, leaf gas exchanges, carbon isotope discrimination (Delta) and carbohydrate status were monitored in de-fruited coffee trees (Coffea arabica L.) grown in the field, from October 1998 ...
Use of different carbon sources in cultivation of baker's yeast for production of glycerol-3-phosphate dehydrogenase
(2013-03-07)
The physiological state of yeast cells changes during culture growth as a consequence of environmental changes (nutrient limitations, pH and metabolic products). Cultures that grow exponentially are heterogeneous cell ...
