1. Nutrients uptake by silver vase bromeliad roots
Resumo As bromélias são desejáveis como plantas de vaso devido as brácteas floridas e formato geralmente grande, colorido e exótico das folhas que formam uma cisterna. A principal função das raízes de bromélias epifíticas é a fixação no substrato, enquanto a captação de água e nutrientes é realizada principalmente pelas folhas. Porém, estud

2. Physiological responses of Eucalyptus urophylla young plants treated with biostimulant under water deficit
Resumo Os bioestimulantes consistem em uma mistura de reguladores de crescimento que, quando aplicados nas plantas, atuam no equilíbrio hormonal, melhorando seu desenvolvimento. Stimulate® é um bioestimulante composto por ácido indolbutírico (0,005%), cinetina (0,009%) e ácido giberélico (0,005%), que promove o crescimento das raízes, melhora a absor

3. Selenium biofortification on garlic growth and other nutrients accumulation
RESUMO O selênio (Se) é elemento essencial para os seres humanos e é considerado anticancerígeno. Alho pode acumular Se, sendo, por isso, uma opção para a suplementação de Se na dieta humana. Assim, o objetivo deste trabalho foi estudar a captação e acúmulo de selênio durante o crescimento do alho e avaliar os efeitos da fortificação de Se. Qua

4. 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

5. 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

6. DIVERSITY OF ARBUSCULAR MYCORRHIZAL FUNGI IN FOREST ECOSYSTEMS OF BRAZIL: A REVIEW
ABSTRACT Plants can stablish symbiosis with arburcular mycorrhiza fungi (AMF), in which the fungus uses carbohydrates synthesized by plant photosynthesis in exchange for soil nutrients. AMF symbiosis may benefit plants by increasing the rates of nutrient uptake, tolerance to abiotic stresses, protection against pathogens and, by promoting resilience of fores

7. Nitrogen and phosphorus uptake efficiency in Indian mustard cultivated during three growth cycles in a copper contaminated soil treated with biochar
RESUMO: O biocarvão tem sido usado mundialmente como um eficiente insumo agrícola devido à sua interação benéfica com as partículas e os nutrientes do solo. Contudo, seu efeito na disponibilidade de nutrientes como N e P em solos tropicais tem sido pouco investigado. O objetivo do estudo foi avaliar o efeito de diferentes tipos e doses de biocarvão

8. Contribution of dark septate fungi to the nutrient uptake and growth of rice plants
ABSTRACT The use of dark septate fungi (DSE) to promote plant growth can be beneficial to agriculture, and these organisms are important allies in the search for sustainable agriculture practices. This study investigates the contribution of dark septate fungi to the absorption of nutrients by rice plants and their ensuing growth. Four dark septate fungi isol

9. Nutrient Uptake by High-Yielding Cotton Crop in Brazil
ABSTRACT: Determining nutrient uptake and accumulation rates by cotton crops is important to define management strategies, especially for transgenic varieties, which are cultivated using high-technology approaches that require substantial investment to maximize yield. Currently in Brazil, the states of Bahia and Mato Grosso are responsible for 84.4 % of the

10. Tree Growth and Nutrient Dynamics in Pine Plantations in Southern Brazil
ABSTRACT For the development of nutrient budget models to recommend lime and fertilizers for agricultural and forestry crops, curves of plant growth and nutrient accumulation are required. Information about how nutrients are partitioned between the different plant organs is also necessary, but still scarce for pine in Brazil. This study evaluated the growth,

11. Nutrient Uptake and Removal by Potato Cultivars as Affected by Phosphate Fertilization of Soils with Different Levels of Phosphorus Availability
ABSTRACT Studies in the past decades have focused on how tuber yield of potato grown on different types of soil is affected by phosphate fertilizer rates. However, little is known about the effects of phosphorus availability in the soil and of phosphate fertilization on nutrient uptake and removal by the main potato cultivars currently grown in Brazil. Thus,

12. Microwave Acid Extraction to Analyze K and Mg Reserves in the Clay Fraction of Soils
ABSTRACT: Extraction of K and Mg with boiling 1 mol L-1 HNO3 in an open system for predicting K and Mg uptake by plants is a method of low reproducibility. The aim of this study was to compare the extraction capacity of different acid methods relative to hydrofluoric acid extraction for K and Mg. A further objective was to develop a chemical extraction metho
