Photosynthesis impairment in cassava leaves in response to nitrogen deficiency
(Plant and Soil, 2018)
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. ...
Glyphosate hormesis attenuates water deficit stress in safflower (Carthamus tinctorius L.) by modulating physiological and biochemical mediators
(2022-03-01)
Changes in photosynthetic machinery can induce physiological and biochemical damage in plants. Low doses of glyphosate have been shown to exert a positive effect in mitigating the deleterious effects of water deficit in ...
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: ...
Chlorophyll fluorescence in partially defoliated grape plants (vitis vinifera l. cv. chardonnay) / fluorescencia de la clorofila en plantas de uva (vitis vinifera l. cv. chardonnay) defoliadas parcialmente
(Universidad Nacional de Colombia - Sede Medellín, 2013)
The chlorophyll content and fluorescence weredetermined in five-year-old grape plants (Vitis vinifera L. cv.Chardonnay) that were subjected to early partial defoliation,in Villa de Leyva, Colombia. The experimental design ...
Eficiencia fotoquímica del fotosistema ii y crecimiento en plantas de curuba (passiflora tripartita (juss.) var. mollissima (kunth)) bajo estrés salino
(Universidad Nacional de Colombia Sede Palmira, 2013)
La curuba (Passiflora tripartita (Juss.) var. mollissima (Kunth)) es un cultivo importante en Colombia, especialmente en el departamento de Boyacá. A pesar de que el estrés osmótico es un limitante en la producción de este ...
Efeitos do aumento da concentração de CO2 atmosférico e da elevação da temperatura em plantas e suas interações biológicas
(Universidade Federal de Minas GeraisUFMG, 2016-04-29)
This thesis evaluated some of the effects of increased atmospheric CO2 and temperature on selected agricultural species and their interactions. The thesis was structured into four chapters: Chapter I presents the current ...
Physiological and biochemical responses of photomorphogenic tomato mutants (cv. Micro-Tom) under water withholding
(Springer, 2016-06-01)
In addition to mediating photomorphogenesis, phytochromes are responsible for many abiotic stress responses, acting upon biochemical and molecular mechanisms of cell signaling. In this work, we measured the physiological ...
Chlorophyll fluorescence emission as a response of pulsed light based-leds in tomato plants
(Springer, 2013-02)
The effects of pulsed light based-LEDs at eleven frequencies (0.1, 1, 10, 50, 100, 500 Hz, 1, 5, 10, 50 and 100 kHz) programmed at 50 % duty cycle were analyzed, obtaining important parameters of the fluorescence emission ...
