Hot air treatment decreases chlorophyll catabolism during postharvest senescence of broccoli (Brassica oleracea L. var. italica) heads
(John Wiley & Sons Ltd, 2006-05)
A hot air treatment was applied to broccoli (Brassica oleracea L. var. italica) florets and its effect on chlorophyll catabolism during postharvest senescence was analyzed. Florets were treated at 48°C for 3 h and then ...
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 ...
ESTIMATE OF THE GRAIN YIELD OF OATS CULTIVATED UNDER IRRIGATION LEVELS USING CHLOROPHYLL METER
(Faema-fac Educacao & Meio Ambiente, 2018-07-01)
The use of indirect measures of vegetation in agriculture, associated with models, is an efficient way of estimating crop productivity. The objective of this study was to verify the accuracy of models to estimate the yield ...
Indirect method for quantifying the content of photosynthetic pigments in genotypes of dwarf elephant grass
(Editora da Universidade Estadual de Maringá (EDUEM), 2013-03-01)
O objetivo deste ensaio foi determinar equações que indiretamente associem os valores obtidos no medidor de clorofila SPAD-502 aos teores de clorofila e carotenóides de genótipos de capim-elefante anão. Folhas de genótipos ...

Avaliação de moléculas de clorofilas e seus derivados em espécies de microalgas cultivadas em fotobiorreatores
(Universidade Federal de Santa MariaBrasilCiência e Tecnologia dos AlimentosUFSMPrograma de Pós-Graduação em Ciência e Tecnologia dos AlimentosCentro de Ciências Rurais, 2017-08-04)
Microalgae are photosynthetic microorganisms, which, in turn, present great potential for insertion in biotechnological processes with the parallel production of biomolecules, such as chlorophylls that are abundantly present ...
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 ...
