Efeitos de nanopartículas magnéticas sobre a microalga Raphidocelis subcapitata
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2016-11-27)
Nanotechnology has developed rapidly in recent decades, characterized as the fourth industrial revolution. In the current market, the use of products that incorporate nanotechnology is ascending. The nanoparticles (NPs) ...
Physiological mechanisms and phytoremediation potential of the macrophyte Salvinia biloba towards a commercial formulation and an analytical standard of glyphosate
Glyphosate (Gly) is the most widely used herbicide in the world and has broad-spectrum and non-selective activity. Its indiscriminate use hence risks contamination of water bodies and can affect living organisms, especially ...
Light-related photosynthetic characteristics of lotic macroalgae
(Kluwer Academic Publ, 2014)
Oxalic acid-mediated biochemical and physiological changes in the common bean-Sclerotinia sclerotiorum interaction
(Plant Physiology and Biochemistry, 2018)
Paraheliotropism can protect water-stressed bean (Phaseolus vulgaris L.) plants against photoinhibition
(Elsevier GmbH, 2004)
In order to estimate the importance of leaf movements on photosynthesis in well-watered and water-stressed field grown bean cultivars (Arroz Tuscola (AT), Orfeo INIA (OI), Bayos Titan (BT), and Hallados Dorado (HD)), CO2 ...
Glyphosate effects on gas exchange and chlorophyll fluorescence responses of two Lolium perenne L. biotypes with differential herbicide sensitivity
Despite the extensive use of glyphosate, how it alters the physiology and metabolism of plants is still unclear. Photosynthesis is not regarded to be a primary inhibitory target of glyphosate, but it has been reported to ...
Effect of UV-B radiation on the contents of UV-B absorbing compounds and photosynthetic parameters in Parmotrema austrosinense from two contrasting habitats
(Wiley Blackwell Publishing, Inc, 2018-09)
We studied the resistance of Parmotrema austrosinense to UV-B stress. We focused on the effects of a high dose UV-B radiation on the content of chlorophylls, carotenoids and UV-B screening compounds. Photosynthetic parameters ...
Effect of phosphorus deficiency on reflectance and chlorophyll fluorescence of cotyledons of oilseed rape (Brassica napus L.)
(Wiley Blackwell Publishing, Inc, 2009-06)
The spectroscopic changes in reflectance and fluorescence caused by phosphorus (P) starvation in Brassica napus L. young plants were evaluated. P deficiency produced an important decrease in reflectance values between 500 ...
Herbivore induction of jasmonic acid and chemical defences reduce photosynthesis in Nicotiana attenuata
(Oxford University Press, 2013-01)
Herbivory initiates a shift in plant metabolism from growth to defence that may reduce fitness in the absence of further herbivory. However, the defence-induced changes in carbon assimilation that precede this reallocation ...
