Pigments and photosynthesis of understory grasses: Light irradiance and soil moisture effects
(Springer, 2016-03)
Phleum alpinum and Poa pratensis are major forage species that often grow in various environments in Tierra del Fuego, Argentina. To investigate how these species acclimate to the different irradiance of the microenvironments ...
Transition dipole moments of the Qy band in photosynthetic pigments
(American Chemical Society, 2011-11)
From studying the time evolution of the single electron density matrix within a density functional tight-binding formalism we calculate the Q y transition dipole moments vector direction and strength for a series of important ...
Blooms of Myrionecta rubra in Bahia de La Paz, Gulf of California, Mexico in early summer 2005
(CICIMAR Oceánides, 2008)
Blooms of the ciliate Myrionecta rubra are quite common in Bahía de La Paz. In June and July 2005, two blooms of this species were sampled to determine abundance, plankton biomass, nutrients, dissolved oxygen, and temperature. ...
Cattleya orchids seedlings in vitro performance under artificial and natural light
(2018-01-01)
In vitro seed germination represents an important alternative to overcome limitations of the orchid conventional propagation. The use of natural light demonstrated potential in promoting in vitro hardiness of tropical ...
Seasonal variations of the photosynthetic activity and pigment concentrations in different reproductive phases of gigartina skottsbergii (rhodophyta, gigartinales) in the magellan region, sub-antarctic chile
Seasonal environmental changes may significantly influence macroalgal diversity and biomass. Cryptogam species richness increases towards the poles, especially in sub-Antarctic environments. Yet, subpolar seaweed biodiversity ...
Synthesis of solar cells sensitized using natural photosynthetic pigments & study for the cell performance under different synthesis parameters
(Institute of Physics Publishing, 2016-06)
In this study we used photosynthetic pigments extracted from spinach and purple cabbage for their potential application in dye sensitized solar cells (DSSC). Pigments were extracted by dissolving small amounts of each one ...
Photosynthetic responses of understory savanna plants: Implications for plant persistence in savannas under tree encroachment
(2018-03-01)
Savannas are ecosystems where plants are expected to have leaf-level adaptations conferring tolerance to high irradiances, which characterizes this type of open canopy vegetation. The neotropical savannas of Brazil (Cerrado) ...
Respostas fisiológicas de cultivares de cana-de-açúcar submetidas à deficiência hídrica e a reidratação
(Univ Fed Rural Semi-arido-ufersa, 2013-01-01)
The aim of this work was to study the physiological responses of three contrasting cultivars of sugar cane subject to water stress and rewatering, The experiment was carried out in a greenhouse, where the cultivars SP83-2847, ...
