1. Nutrient stock and nutritional efficiency of woody species in dry tropical forest as reforestation indicators
ABSTRACT Efficient forest species can be indicated for reforesting environments, which present nutritional restriction. The objective of this study was to determine the nutrient stock in leaf biomass of the species of greatest importance value (IV) in a tropical dry forest fragment, as well as to evaluate the nutritional efficiency of these species as refore

2. Nutritional study of Schinus terebinthifolius (Raddi) in response to potassium fertilization
Resumo O objetivo deste trabalho foi avaliar o efeito de doses de K no desenvolvimento inicial e eficiência nutricional de mudas da aroeirinha. Para isso foi desenvolvido em casa de vegetação um experimento em vasos com cinco doses de K2O (66,67, 133,33, 200, 266,67 e 333,33 mg kg-1), dispostos em delineamento experimental de blocos casualizados, com cinc

3. Incidence of stalk rots in corn hybrids influenced by sowing time and nitrogen rates
ABSTRACT Stalk rots compromise the translocation of water and nutrients, affecting grain filling. This study aimed to quantify the incidence of stalk rots in corn hybrids depending on sowing time and nitrogen topdressing rate, and to assess any correlation with grain yield. The experiment was conducted under field conditions in Atalanta, Santa Catarina state

4. Potential of hydrogen (pH) differentially modulates cadmium stress response in abscisic acid-deficient sitiens tomato mutant
ABSTRACT Uptake of nutrients and cadmium (Cd) are dependent upon many factors, including plant species, ions concentration and pH. Tolerance to Cd-induced oxidative stress can be modulated by phytohormones such as abscisic acid (ABA), which induce the production of reactive oxygen species, activating proteins and enzymes involved in stress response and possi

5. Phosphorus-Zinc Interaction and Iron and Manganese Uptake in the Growth and Nutrition of Phalaenopsis (Orchidaceae)
ABSTRACT: Visual symptoms of Zn deficiency, induced by excessive P applications, have been observed in commercial orchid nurseries. The supply of other metallic micronutrients, such as Fe and Mn, may also be inadequate in the plant due to high application rates of P. The aim of this study was to investigate this interaction in the nutrition of Phalaenopsis p

6. Avaliação de fontes, absorção foliar e translocação de zinco (68Zn) em laranjeiras / Sources evaluation, foliar uptake and zinc translocation (68Zn) in Orange
Studies of zinc fertilization on citrus foliar developed in Brazil are mostly limited to information of the nutrients quantities absorbed by the leaves, but the zinc transport of the leaves to other parts of the plants need to be clarified. Most investigations on this subject is vast array of conflicting results. As a result, the use of stable isotope techni

7. Mosaicos sucessionais em florestas tropicais: efeitos sobre o forrageio e deposição de fezes pela anta Tapirus terrestris (Perissodactyla: Tapiridae) / Successional mosaics in tropical forests: effects on foraging and dung deposition by tapirs Tapirus terrestris (Perissodactyla: Tapiridae)
Grandes mamíferos herbívoros exercem papel fundamental para a função e estrutura dos ecossistemas terrestres, através principalmente da herbivoria e da deposição de fezes e urina, que influenciam a germinação e crescimento de plantas, a composição e diversidade de comunidades vegetais, a ciclagem e translocação de nutrientes, o estoque de carbon

8. Nutrient flux associated with the emergence of Quesada gigas Olivier (Hemiptera: Cicadidae) in an urban ecosystem
Large-bodied arthropods, such as cicadas, can be able to reallocate significant amounts of nutrients during adult emergence. Evidence suggests that Quesada gigas Olivier emergence constitutes an important nutrient flux from belowground to aboveground. The purpose of this study was to estimate the amount of nitrogen, proteins, and lipids resulting from the em

9. Morfoanatomia e composição mineral de raízes de duas espécies de restinga submetidas ao excesso de ferro / Morphoanatomy and mineral composition of roots from two species of restinga submitted to iron excess
In the south coast of Espírito Santo, Brazil, the restinga has received in the last years, an additional increment of iron, due to activities of iron ore industries. It was objectified to characterize the roots structure of the native restinga species, Ipomoea pescaprae L. (Convolvulaceae) and Canavalia rosea DC. (Fabaceae), with the iron plaque development

10. Marcha de absorção de nutrientes, produção e qualidade de hastes florais de plantas de tango (Solidago canadensis L.) / Nutrient uptake, production and quality of Canada Goldenrod plants floral stems (Solidago canadensis L.)
With the purpose of characterizing the concentration and accumulation of nutrients on Canada Goldenrod leaves with different number of stems along a period, an experiment was driven on the greenhouse on the Floriculture Sector DFT/UFV, using the randomized block design, in factorial outline 3x7 (plants with one, two and three steams and collected in 0, 15, 3

11. Relação entre diversidade arbórea e aspectos do ciclo biogeoquímico de uma floresta monodominante de Brosimum Rubescens Taub. e uma floresta mista no Leste Mato-Grossense / Relação entre diversidade arbórea e aspectos do ciclo biogeoquímico de uma floresta monodominante de Brosimum Rubescens Taub. e uma floresta mista no Leste Mato-Grossense
Tropical monodominant forests in which one species represents more than 50% of the above ground biomass are a rare vegetation type. One of these forests is found in the eastern region of the State of Mato Grosso where the tree species Brosimum rubescens Taub. (Moraceae), accounts for more than 80% of the above ground biomass of the forest community. This sit

12. Accumulation and long-term behavior of radiocaesium in tropical plants
The accumulation and distribution of 40K and 137Cs in tropical plant species were studied through measurements of gamma-ray spectra from mango, avocado, guava, pomegranate, chili pepper, papaya and manioc trees. Our goal was to infer their differences in the uptake and translocation of ions to the aboveground plant parts and to establish the suitability of u
