Stem canker caused by Phomopsis spp. induces changes in polyamine levels and chlorophyll fluorescence parameters in pecan leaves
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2021-06)
Pecan plants are attacked by the fungus Phomopsis spp. that causes stem canker, a serious and emerging disease in commercial orchards. Stem canker, which has been reported in several countries, negatively affects tree ...
Stem canker caused by Phomopsis spp. Induces changes in polyamine levels and chlorophyll fluorescence parameters in pecan leaves
(Elsevier, 2021-09)
Pecan plants are attacked by the fungus Phomopsis spp. that causes stem canker, a serious and emerging disease in commercial orchards. Stem canker, which has been reported in several countries, negatively affects tree ...
Arsenic toxicity in soybean plants: Impact on chlorophyll fluorescence, mineral nutrition and phytohormones
(Springer, 2021-08)
Arsenic (As) is naturally present in soils and groundwater in agricultural areas, mainly in the form of arsenate (AsV) and arsenite (AsIII). It can enter soybean plants and decrease their yield and growth, therefore posing ...
Chlorophyll a fluorescence analysis reveals divergent photosystem II responses to saline, alkaline and saline–alkaline stresses in the two Lotus japonicus model ecotypes MG20 and Gifu-129
(Springer Heidelberg, 2019-09)
Saline and alkaline stresses affect more than 10% of the World’s arable land, limiting agricultural production. Salt-induced stress may affect the photosystem II (PSII) function, altering fluorescence emission. Therefore, ...
Glyphosate effects on gas exchange and chlorophyll fluorescence responses of two Lolium perenne L. biotypes with differential herbicide sensitivity
(2012-08)
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 ...
Early responses to Fe-deficiency distinguish Sorghum bicolor genotypes with contrasting alkalinity tolerance
(Pergamon-Elsevier Science Ltd, 2018-11)
Soil alkalinity is a significant limitation to agricultural productivity and it is associated to several soil features, among them, Fe deficiencies. In this work, we explored the hypothesis that alkalinity tolerance in ...
Differential effects of NaCl and Na2SO4 on the halophyte Prosopis strombulifera are explained by different responses of photosynthesis and metabolism
(Elsevier Masson, 2019-08)
Prosopis strombulifera (Lam.) Benth. is a halophytic shrub found in highly saline soils in Argentina, with high tolerance against NaCl but strong growth inhibition by Na2SO4. In the present study, the differences in the ...
Canopy active fluorescence spectrum tracks ANPP changes upon irrigation treatments in soybean crop
(Elsevier Science Inc., 2021-09)
Accurate estimation of aerial net primary production (ANPP) using remotely acquired data is one of the main challenges in both environmental monitoring and precision agriculture. Reflectance-based techniques have been ...
Chlorophyll fluorescence and biomass partitioning within light and nitrogen deficiency: An example of the use of the R programming language for teachingFluorescencia de clorofila y la partición de biomasa en condiciones de deficiencia de luz y nitrógeno: un ejemplo del uso del lenguaje de programación R para la docencia
