Eficiencia fotoquímica máxima e índice de potencial fotosintético en plantas de melón (Cucumis melo) tratadas con bajas temperaturasMaximum efficiency phothochemistry and potential photosynthetic index in melon plants (Cucumis melo) treated with low temperaturas
(Universidad Nacional del Litoral. Facultad de Ciencias Veterinarias, 2014)
La fluorescencia de la clorofila se utiliza para determinar la eficiencia fotoquímica de las plantas
ante diferentes condiciones ambientales. Existen índices como Fv/Fm y PI abs que son indicadores
indirectos del rendimiento ...
Heat and water stressed field-grown soybean: A multivariate study on the relationship between physiological-biochemical traits and yield
(Pergamon-Elsevier Science Ltd, 2018-04)
Heat stress (HS) combined with water stress (WS) negatively impact soybean [Glycine max (L.) Merr.] production. The aims of this research were to quantify the combined effect of HS and WS during grain filling (GF) on grain ...

Quantitative Effects of Pigmentation on the Re‐absorption of Chlorophyll a Fluorescence and Energy Partitioning in leaves
(Wiley Blackwell Publishing, Inc, 2019-11)
This study comparatively examined spectroscopic features, photosynthetic parameters and energy partitioning in plants of Fittonia albivenis cv. Agyroneura and Fittonia albivenis cv. Verschaffeltii with different pigmentation. ...
Effects of solar ultraviolet radiation on photosynthesis of the marine red tide alga Heterosigma akashiwo (Raphidophyceae)
(Elsevier Science Sa, 2007-02)
In order to assess the short- and long-term impacts of UV radiation (UVR, 280–400 nm) on the red tide alga, Heterosigma akashiwo, we exposed the cells to three different solar radiation treatments (PAB: 280–700 nm, PA: ...
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 ...
1-Methyl cyclopropene extends postharvest life of spinach leaves
(Elsevier Science, 2010-03)
Senescence of detached spinach leaves either untreated or treated with 0.1 or 1.0 μL L−1 1-MCP has been investigated. 1-MCP treated leaves had higher chlorophyll content and photosystem II potential quantum yield (Fv/Fm) ...
Hydraulic constraints on photosynthesis in subtropical evergreen broad leaf forest and pine woodland trees of the Florida Everglades
(Springer, 2010-06)
The relationship between water transport and photosynthesis represents the trade-off between carbon gain and water loss and was used to evaluate potential differences in water resource utilization among two dominant ...
Increase in rubisco activity and gene expression due to elevated temperature partially counteracts ultraviolet radiation-induced photoinhibition in the marine diatom thalassiosira weissflogii
(American Society of Limnology and Oceanography, 2011-07)
We performed outdoor experiments to evaluate the effect of temperature on photoinhibition properties in the cosmopolitan diatom Thalassiosira weissflogii. Cultures were exposed to solar radiation with or without ultraviolet ...
