Tolerance to iron chlorosis in non-grafted quince seedlings and in pear grafted onto quince plants
(Soc Chilena Ciência Suelo, 2011-01-01)
Grafting is a technique that may affect plant tolerance to iron chlorosis in plants cultivated for their fruit. Therefore, the objective of this study was to evaluate the tolerance of non-grafted quince seedlings and pear ...
Residual phosphate fertilization and Azospirillum brasilense in the common bean in succession to maize intercropped with Marandu grass
(2017-01-01)
One of the alternatives for achieving sustainable agriculture and a reduction in production costs, especially with phosphate fertilisers, is to inoculate seeds with bacteria of the genus Azospirillum. The aim of this study ...
Elucidating the action mechanisms of silicon in the mitigation of phosphorus deficiency and enhancement of its response in sorghum plants
(2021-01-01)
Phosphorus (P) is one of the most limiting nutrients in agricultural production and silicon (Si) application is a strategy used to improve phosphate nutrition in plants; however, the action mechanisms of Si remain poorly ...
Physiological and biochemical responses of sugarcane to oxidative stress induced by water deficit and paraquat
(2015-08-06)
Physiological and biochemical responses to oxidative stress induced by paraquat or water deficit were examined in this study with respect to photoinhibition, stomatal conductance, photosynthetic pigments, organic solutes, ...
Change in the physiological and biochemical aspects of tomato caused by infestation by cryptic species of bemisia tabaci med and meam1
(2021-12-01)
Infestation by Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) causes damage to tomatoes with production losses of up to 100%, affecting the physiological and biochemical aspects of host plants. The objective of this ...
Physiological and biochemical responses of the iron chlorosis tolerant grapevine rootstock 140 Ruggeri to iron deficiency and bicarbonate
(Springer, 2013)
Background and aims Iron (Fe) deficiency chlorosis
associated with high levels of soil bicarbonate is one
of the main nutritional disorders observed in sensitive
grapevine genotypes. The aim of the experiment was
to ...
Research of Geochemical Parameters in the São Paulo River, Todos Os Santos Bay, Bahia, Brazil.
(Medwin PublishersBrasil, 2017-03-24)
Contamination of coastal environments is a significant environmental problem, affecting several regions around the
world, especially in areas close to industries and urban centres. Some elements, when present in high ...
Plankton in waters adjacent to the Laje de Santos state marine conservation park, Brazil: spatio-temporal distribution surveys
(Inst Oceanografico, Univ Sao Paulo, 2017)
The coastal marine plankton plays a major role in ecosystem functioning by linking pelagic and benthonic environments through energy fluxes. Understanding the dynamic of planktonic organisms is also crucial for conservation ...
Growth and hydrogen production of outdoor cultures of Synechocystis PCC 6803
(2016)
Synechocystis sp. PCC 6803, a freshwater cyanobacterium, was cultivated outdoors in a 50 L tubular photobioreactor to study the acclimation of cells to solar light in cultures grown at different initial mean biomass ...
Tolerance and sorption of Bromacil and Paraquat by thermophilic cyanobacteria Leptolyngbya 7M from Costa Rican thermal springs
(2019)
We studied the adsorption ability and tolerance of the thermophilic filamentous cyanobacteria Letolyngbya 7M towards Paraquat and Bromacil. Adsorption isotherms at pH = 7.0 showed an adsorption capacity of 24.4 mg/g and ...
