Effect of arsenic on reflectance spectra and chlorophyll fluorescence of aquatic plants
(Elsevier, 2015-01)
Arsenic pollution of groundwater is a serious problem in many regions of Latin America that causes severe risks to human health. As a consequence, non-destructive monitoring methodologies, sensitive to arsenic presence in ...
Chlorophyll fluorescence response of Pinus radiata clones to nitrogen and phosphorus supply
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2009)
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 ...
In vivo observation of chlorophyll fluorescence quenching induced by gold nanoparticles
(ElsevierLausanne, 2011-12)
To our knowledge, the present work reports the first in vivo observation of chlorophyll a fluorescence quenching induced by gold nanoparticles. Laser-induced fluorescence spectroscopy was used to collect in vivo chlorophyll ...
Chlorophyll fluorescence, photochemical reflective index and normalized difference vegetative index during plant senescence
(Elsevier Gmbh, Urban & Fischer Verlag, 2016-07)
The relationship between the Photochemical Reflectance Index (PRI), Normalized Difference Vegetation Index (NDVI) and chlorophyll fluorescence along senescence was investigated in this work. Reflectance and radiance ...
Atrazine and Methyl viologen effects on Chlorophyll-a fluorescence revisited. Implications in Photosystems Emission and Ecotoxicity Assessment
(Wiley, 2014-01)
In this work, we use the effect of herbicides that affect the photosynthetic chain at dened sites in the photosynthetic reaction steps to derive information about the uorescence emission of photosystems. The interpretation ...
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 ...
Effect of herbicides based on glyphosate on the photosynthesis of green macroalgae in tropical lotic environments
(2021-09-01)
The susceptibility of aquatic environments to contamination by glyphosate has been of worldwide con-cern, mainly since this herbicide affects important physiological processes such as photosynthesis. Considering this, we ...
SATELLITE FLUORESCENCE AS A MEASURE OF OCEAN SURFACE CHLOROPHYLL
