Chlorophyll fluorescence as a marker for herbicide mechanisms of action
(Academic Press Inc. Elsevier B.V., 2012-03-01)
Photosynthesis is the single most important source of 02 and organic chemical energy necessary to support all non-autotrophic life forms. Plants compartmentalize this elaborate biochemical process within chloroplasts in ...
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 ...
Changes in leaf gas exchange and chlorophyll a fluorescence on soybean plants supplied with silicon and infected by Cercospora sojina
(Journal of Phytopathology, 2019)
EFFECT OF DIFFERENT ROOTSTOCKS ON GROWTH, CHLOROPHYLL A FLUORESCENCE AND MINERAL COMPOSITION OF TWO GRAFTED SCIONS OF TOMATO
(2013-01-01)
Two tomato scions (cvs. 'Raf' and 'Gorety') were grafted on three different rootstocks: S. torvum, 'Beaufort' (Lycopersicum esculentum × Lycopersicum hirsutum) and intermediate grafting of eggplant 'Cristal' between tomato ...
Chlorophyll a spatial inference using artificial neural network from multispectral images and in situ measurements
(2013-04-01)
Considering the importance of monitoring the water quality parameters, remote sensing is a practicable alternative to limnological variables detection, which interacts with electromagnetic radiation, called optically active ...
Fluorescence imaging of light acclimation of brazilian atlantic forest tree species
(Photosynthetica, 2018)
Iron excess affects rice photosynthesis through stomatal and non-stomatal limitations
(Plant Science, 2018)
Responses of chlorophyll fluorescence parameters of the facultative halophyte and C-3-CAM intermediate species Mesembryanthemum crystallinum to salinity and high irradiance stress
(Elsevier B.V., 2007-07-01)
Mesembryanthemum crystallinum L. (Aizoaceae) is a facultative annual halophyte and a C-3-photosynthesis/crassulacean acid metabolism intermediate species currently used as a model plant in stress physiology. Both salinity ...
Photosynthesis impairment in cassava leaves in response to nitrogen deficiency
(Plant and Soil, 2018)
Use of Physiological Parameters in Screening Drought Tolerance in Sugarcane Genotypes
(2011-09-01)
The physiological response of four commercial sugarcane genotypes to water stress was evaluated by measuring the photochemical efficiency of the photosystem II (chlorophyll a fluorescence ratio, F v/F m), estimated chlorophyll ...
