1. Trocas gasosas em Vitis vinifera sob regime de estress hidrico. III. Acido abscisico e comportamento varietal.
O efeito da aplicacao de um estresse hidrico sobre a regulacao das trocas gasosas e acumulo do acido abscisico (ABA) em folhas de diferentes cultivares de Vitis vinifera L. foi analisado com o objetivo de caracterizar o comportamento varietal e identificar um marcador para as diferentes formas de resposta. Foram utilizadas plantas de dois anos, enxertadas so

2. Caracterização microclimática, ecofisiológica e fitossociológica em uma floresta estacional semidecidual secundária, em Viçosa, MG / Microclimatic, ecophysiological and phytosociological characterization of a secondary semideciduous seasonal forest, in Viçosa, MG, Brazil
A study in the domain of the Atlantic Forest was carried out in ten sites with different slope, aspect and topographic position at the Estação Experimental Mata do Paraíso, in Viçosa, Minas Gerais State, Brazil (20o45 Latitude South, 42o55 Longitude West and an average altitude of 690 m). The spatial and temporal characterization of the photosyntheticall

3. Dark Stomatal Movement in Sunflowers in Response to Illumination under Nitrogen
Experiments were performed on intact sunflowers (Helianthus annuus) placed in a specially designed experimental chamber which allows instantaneous modifications of the atmospheric composition without changing any other conditions. After one night in normal conditions, the plant was illuminated under pure nitrogen atmosphere; the opening stomatal movement, me

4. Effect of Vanadate on Bean Leaf Movement, Stomatal Conductance, Barley Leaf Unrolling, Respiration, and Phosphatase Activity 1
Vanadate (Na3 VO4) inhibits leaf movement and stomatal conductance of Phaseolus vulgaris L. cv. Carlos Favorit in light-dark cycles as well as photomorphogenetic leaf unrolling of Hordeum vulgare L. cv. Rupal. Inhibition was 50% by 10 to 100 micromolar vanadate and 100% by millimolar vanadate. Leaf unrolling was also inhibited by oligomycin and diethylstilbe

5. Effects of Phenylmercuric Acetate on Stomatal Movement and Transpiration of Excised Retula papyrifera Marsh. Leaves 1
Effects of 10−3m, 10−4m, and 10−5m phenylmercuric acetate (PMA) on stomatal movement and transpiration of excised Betula papyrifera leaves were investigated. Duco cement leaf prints and transpiration decline curves were used for the analysis of stomatal condition. PMA induced stomatal closure and decreased transpiration. Stomata of leaves treated with

11. Actin Filaments in Mature Guard Cells Are Radially Distributed and Involved in Stomatal Movement.
Stomatal movements, which regulate gas exchange in plants, involve pronounced changes in the shape and volume of the guard cell. To test whether the changes are regulated by actin filaments, we visualized microfilaments in mature guard cells and examined the effects of actin antagonists on stomatal movements. Immunolocalization on fixed cells and microinject
