Growth and nutritional efficiency of watermelon plants grown under macronutrient deficiencies
(2019-04-01)
Biological damage caused by macronutrient deficiency in watermelon plants is still not known, and may lead to nutritional disorders and alterations in absorption and utilization efficiencies, depending on the evaluated ...
Uso racional de nutrientes no cultivo hidropônico de amorperfeito
(2006-07-01)
The objective of this work was to evaluate different concentrations of nutritional solution in the hydroponic cultivation of Viola x wittrockiana Gams. The experiment was conducted in DFT hydroponic system, in a completely ...
Concentração e redistribuição de nutrientes minerais nos diferentes estádios foliares de seringueiraConcentration and redistribution of mineral nutrients at different stages in the development of the rubber tree leaf.
(Instituto Nacional de Pesquisas da Amazônia, 2012)
A seringueira na fase adulta possui um crescimento intermitente com o processo de troca de folhas, que é caracterizado pela senescência. Esse é um mecanismo que as árvores utilizam para reciclarem os nutrientes, por meio ...

Kinetics of zinc uptake and anatomy of roots and leaves of coffee trees as affected by zinc nutrition
(Taylor & Francis Inc, 2005-01-01)
Zinc (Zn) uptake kinetics and root and leaf anatomy were studied in coffee trees grown in nutrient solutions with or without Zn. Leaves and roots were sampled and cuts were made in the medium part of the leaves and in root ...
Exportação de nutrientes e qualidade de cultivares de rosas em campo e em ambiente protegido
(Associação Brasileira de Horticultura, 2008-12-01)
Foram avaliadas a exportação de nutrientes por cultivares de rosas e as características que refletem qualidade em campo e ambiente protegido. O delineamento experimental foi inteiramente casualizado, sendo os tratamentos ...
Biomass, carbon and nutrient storage for dominant grasses of cold temperate steppe grasslands in southern Patagonia, Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2010-01)
We hypothesized that different dominant grasses species display contrasting nutrient accumulation, allocation and conservation strategies. Also, we expect a distinctive pattern of carbon and biomass partitioning according ...
Effects of nutrient enrichment on epipelic diatom assemblages in a nutrient-rich lowland stream, Pampa Region, Argentina
(Springer, 2015-09-03)
We analyzed the diatom assemblages inhabiting the epipelic biofilm of a Pampean stream, characterized by their high basal nutrient levels, when exposed to a continuous surplus of inorganic nutrients. An in situ experience ...
Photochemical activity of PSII of tropical phytoplankton communities of Southern Brazil exposed to solar radiation and nutrient addition
(Elsevier Science Inc, 2014)
We carried out short- and mid-term incubations to assess the combined impact of solar ultraviolet radiation (UVR, 280-400nm) and nutrient addition on tropical phytoplankton communities from BabitongaBay, Southern Brazil. ...
