The effect of chilling on the photosynthetic activity in coffee (Coffea arabica L.) seedlings. The protective action of chloroplastid pigments
(2002-12-01)
Coffea arabica is considered to be sensitive to low temperatures, being affected throughout its entire life cycle. Injury caused by chilling (low temperatures above zero degree centigrade) is characterized primarily by ...
Evaluation of Rhodocyclus gelatinosus biomass for broiler pigmentation
(Poultry Science Assoc Inc, 2002-03-01)
We evaluated the influence of dietry inclusion of corn gluten meal, apocartenoic acid ethyl ester (APO-EE), canthaxanthin, and Rhodocylus gelatinosus R-1 biomass on broiler carcass color. These oxycarotenoid sources were ...
Alterations in chlorophyll a fluorescence, pigment concentrations and lipid peroxidation to chilling temperature in coffee seedlings
(2009-11-01)
Coffea arabica L. is considered to be sensitive to low temperatures throughout its life cycle. In some Brazilian regions, seedling production occurs under shade conditions and during the winter, with average temperatures ...

Respostas fisiológicas de cultivares de cana-de-açúcar submetidas à deficiência hídrica e a reidratação
(2013-12-01)
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, ...
Nitric oxide reduces oxidative stress generated by lactofen in soybean plants
(Academic Press Inc. Elsevier B.V., 2010-05-01)
Nitric oxide (NO) is a molecule able to directly scavenge ROS and end chain reactions, which can be generated by some herbicides This study aimed to evaluate whether the pretreatment of soybean plants with sodium nitroprusside ...
Physiological and biochemical responses of sugarcane to oxidative stress induced by water deficit and paraquat
(2015-08-06)
Physiological and biochemical responses to oxidative stress induced by paraquat or water deficit were examined in this study with respect to photoinhibition, stomatal conductance, photosynthetic pigments, organic solutes, ...
Photosynthetic pigments, nitrogen status, and flower behavior in eggplant exposed to different sources and levels of potassium
(2012)
The aim of this study was to investigate (i) the influence of different sources and levels of potassium on photosynthetic pigments, (ii) measure nitrogen status in leaf, (iii) evaluate flower behavior in eggplant (Solanum ...
