1. CHICKEN MANURE AND LUMINOUS AVAILABILITY INFLUENCE GAS EXCHANGE AND PHOTOCHEMICAL PROCESSES IN Alibertia edulis (Rich.) A. Rich SEEDLINGS
ABSTRACT Information on the physiological responses of native plants from the Brazilian Cerrado regarding the use of chicken manure and luminosities are important for their silvicultural management. Thus, aimed to evaluate the effect of chicken manure and luminous availability on the photosynthetic metabolism of Alibertia edulis (Rich) A. Rich. The experimen

2. Spondias rootstock in the formation of seedlings of the yellow mombin
RESUMO O objetivo deste trabalho foi determinar o efeito de porta-enxertos de Spondias na formação de mudas enxertadas de cajazeira. O experimento foi instalado no Campo Experimental da Embrapa, em Pacajus-CE no delineamento inteiramente casualizado, com quatro tratamentos (porta-enxertos), cinco repetições e dez mudas/parcela. Os porta-enxertos de pé-f

4. Using White Star (Nymphoides humboldtiana) for lake landscaping
RESUMO Estrela Branca (Nymphoides humboldtiana), espécie nativa da flora brasileira, proveniente de ambientes aquáticos, foi selecionada visando seu uso como planta ornamental em lagos. Plantas de Estrela Branca foram submetidas a dois níveis de água (nível alto, até 30 cm de lâmina de água e nível baixo, até a saturação do substrato) e duas inte

5. Management Of Commelina benghalensis with Saflufenacil in Shaded Environments
RESUMO: O uso repetitivo de glyphosate no controle de plantas daninhas em plantios de eucalipto tem selecionado espécies tolerantes a esse herbicida, como a Commelina benghalensis. Diante disso, torna-se necessária a aplicação de herbicidas de outros mecanismos de ação, como o saflufenacil, em rotação ou em mistura com o glyphosate, para reduzir os d

6. Experimental reproduction of cyanogenic poisoning by star grass (Cynodon nlemfuensis Vanderyst var. nlemfuensis cv. “Florico”) in cattle
RESUMO: Descreve-se a reprodução experimental da intoxicação cianogênica por grama estrela (Cynodon nlemfuensis vanderyst var. nlemfuensis cv. ‘Florico’) em bovinos. A grama estrela foi plantada em quatro piquetes em área sombreada (1, 2, 3 e 4) e em três piquetes em área ensolarada (5, 6 e 7) e foram adubados com o equivalente a 0, 750, 200 ou 1

7. Influence of Seasonality and Sunlight Effects on Rollinia mucosa Leaves Fingerprint
Rollinia mucosa fruit has generated great interest due to the presence of bioactive compounds, which exhibit promising biological activities. Fingerprinting analytical techniques, chromatographic-diode array detection (DAD), infrared, mass spectrometric, 1H and 13C nuclear magnetic resonance (NMR) spectra, associated with chemometric analysis and mixture des

8. Anatomy and microscopy of Piper caldense, a folk medicinal plant from Brazil
ABSTRACT Piper caldense C. DC., Piperaceae, commonly known as “pimenta-d’água”, “pimenta-darda” or “paguarandy” in Brazil, is a shrub that grows mainly in humid and shaded habitats. The present study investigates the anatomy of the leaves and stems of P. caldense by light and scanning electron microscopy in order to provide supporting data for

9. Leaf phenotypic variation and developmental instability in relation to different light regimes
ABSTRACT For pioneer plants, shaded habitats represent a stressful condition, where sunlight exposure is below the optimum level and so leaves expand in order to intercept a greater amount of light. We investigated changes in both phenotypic variation and stress of Bauhinia brevipes in sunny and shaded microhabitats. Leaf area was used as a measure of phenot

10. Discrimination of Annona muricata and Rollinia mucosa Extracts by Using Multivariate Curve Resolution and Partial Least-Squares Regression of Liquid Chromatography-Diode Array Data
Species of the Annonaceae family are used in traditional medicine, and several antitumor acetogenins have been isolated from the leaves of Annona muricata and Rollinia mucosa. Leaves samples (self-shaded and sun-exposed) of these species were collected during winter and summer seasons. Extraction media were prepared from mixtures of five solvents according t

11. Ecophysiology of deciduous plants grown at different densities in the semiarid region of Brazil
Physiological differences in the Cordia oncocalyx tree growing at different densities in two distinct areas were investigated. An agrosilvopastoral system (AGP) and a secondary forest (SF) were studied. Under both types of land-use, C. oncocalyx presented a relative frequency of approximately 50%, and absolute densities of 670 and 80 individuals per hectare,

12. Vegetative and productive aspects of organically grown coffee cultivars under shaded and unshaded systems
Although Coffea arabica species has its origin in the African understories, there is great resistance on the part of the Brazilian producers for growing this species under agroforestry systems as they fear that shading reduces production. This study aimed at evaluating some vegetative traits and the productivity of organically grown coffee (Coffea arabica L.
