ABSTRACT The economic exploitation of macaw palm [Acrocomia aculeate(Jacq.) Lodd. ex Mart.] is currently in transition, from extractivism to agricultural cultivation, thus requiring studies on the fertilization of the crop. This study evaluated the response of three genotypes of macaw palm to increasing rates of nitrogen and potassium, grown in the field until the 2nd year and to establish reference contents of mineral nutrients in the leaf. The experiment was a split-plot randomized block design with five main treatments (N and K rates) and three secondary treatments (genotypes), with three replications, each plot containing three plants. Plant height, leaf number, vigor, and nutrient contents in leaf tissues were evaluated at the end of 2nd year of...

Orthophytum grossiorum is a typical bromeliad from Atlantic forestry threatened of extinction. The objectives of this research were to select O. grossiorum clones with ornamental values easy to propagate in vitro, and establish in vitro propagation protocols for these clones. The project was developed in three steps: germination and in vitro selection of seedlings responsive to BAP (6-benzylaminopurine), selection of clones with ornamental values, and establishment of protocol for in vitro propagation of the selected clones. In the first step only 18.33% of plantlets germinated in vitro were responsive to BAP. These plantlets were selected and replicated in vitro several times, each replicated plantlet constituting a clone. In the second step these clones...

Repetibilidade em características biométricas do fruto de macaúba
Provedor de dados: 65
Autores: Manfio,Candida Elisa; Motoike,Sérgio Yoshimitsu; Santos,Carlos Eduardo Magalhães dos; Pimentel,Leonardo Duarte; Queiroz,Vanessa de; Sato,Aurora Yoshiko.
Estimativas do coeficiente de repetibilidade têm sido utilizadas no estudo de caracteres de várias espécies de palmeiras, auxiliando na definição do número e período adequado de avaliações dos genótipos para maior eficiência dos programas de melhoramento. Para macaúba, não há relatos de estudos dessa natureza. Nesse contexto, faz-se importante a determinação do coeficiente de repetibilidade das seguintes características biométricas dos frutos: peso do fruto, volume do fruto, diâmetro equatorial do fruto, peso da amêndoa, volume da amêndoa, diâmetro da amêndoa e espessura do endocarpo; e a determinação do número mínimo de avaliações para um eficiente processo de seleção e avaliação de subamostras de macaúba. O trabalho foi desenvolvido no Departamento de...

Changes in oxidative markers, endogenous antioxidants and activity of the enzyme acetylcholinesterase in farmers exposed to agricultural pesticides - a pilot study
Provedor de dados: 65

Agricultural practices are directly related to the use of pesticides, which indiscriminately and without due care may contribute to the occurrence of numerous intoxications. Several studies have demonstrated the relationship of certain pesticides and the occurrence of oxidative stress and therefore, in recent years have developed methods of analysis of several biomarkers of cellular damage that can be measured and quantified. In this context, the objective of this study was to evaluate the possible changes in biochemical markers: glutamic aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, urea, total protein, and oxidative markers such as lipid peroxidation, damage to proteins and the activity of the enzymes acetylcholinesterase...
