Depletion of the heaviest stable N isotope is associated with NH4+/NH3 toxicity in NH4+-fed plants
(BioMed Central, 2011)
Artículo / Artikulua,
Background: In plants, nitrate (NO3-) nutrition gives rise to a natural N isotopic signature (δ15N), which correlates
with the δ15N of the N source. However, little is known about the relationship between the δ15N of the ...
Effect of feeding regime on composting in bins
(Taylor & Francis, 2017)
Artículo / Artikulua,
Composting in bins is one of the most practical home composting methods. There is currently a need for greater information to improve the management of the composting process and to create home composting programs, which ...
Isotopic composition of maize as related to N-fertilization and irrigation in the Mediterranean region
(Escola Superior de Agricultura "Luiz de Queiroz", Universidade de São Paulo, 2011)
info:eu-repo/semantics/article,
Nitrate leaching as a result of excessive application of N-fertilizers and water use is a major
problem of vulnerable regions. The farming of maize requires high N fertilization and water inputs in Spain.
Isotopic ...
Yield and quality of sugar snap pea in the Ebro Valley: sowing date and seed density
(Escola Superior de Agricultura "Luiz de Queiroz", Universidade de São Paulo, 2012)
info:eu-repo/semantics/article,
Sugar snap pea (Pisum sativum L. var. macrocarpon Ser.) is an edible-podded sweet
pea that is being considered as a new totally mechanized crop to supply raw material to the
agri-food industry of the Ebro Valley (Northern ...
Leaf δ15N as a physiological indicator of the responsiveness of N2-fixing alfalfa plants to elevated CO2, temperature and low water availability
(Frontiers Media, 2015)
info:eu-repo/semantics/article,
The natural 15N/14N isotope composition (δ15N) of a tissue is a consequence of its N source and N physiological mechanisms in response to the environment. It could potentially be used as a tracer of N metabolism in plants ...
Pea plant responsiveness under elevated [CO2] is conditioned by the N source (N2 fixation versus NO3 fertilization)
(Elsevier, 2013)
info:eu-repo/semantics/article,
The main goal of this study was to test the effect of [CO2] on C and N management in 2different plant organs (shoots, roots and nodules) and its implication in the 3responsiveness of exclusively ...
Unravelling the mechanisms that improve photosynthetic performance of N₂-fixing pea plants exposed to elevated [CO₂]
(Elsevier, 2014)
info:eu-repo/semantics/article,
Although the predicted enhanced photosynthetic rates of plants exposed to elevated [CO₂] are expected to increase carbohydrate and plant growth, recent findings have shown a complex regulation of these
processes. The aim ...
Elevated CO2 improved the growth of a double nitrate reductase defective mutant of Arabidopsis thaliana: the importance of maintaining a high energy status
(Elsevier, 2017)
info:eu-repo/semantics/article,
Impairments in leaf nitrogen (N) assimilation in C3 plants have been identified as processes conditioning photosynthesis under elevated [CO2], especially when N is supplied as nitrate. Leaf N status is usually improved ...
Unraveling the role of transient starch in the response of Arabidopsis to elevated CO2 under long-day conditions
(Elsevier, 2018)
info:eu-repo/semantics/article,
Previous studies on Arabidopsis under long-term exposure to elevated CO2 have been conducted using starch synthesis and breakdown mutants cultured under short day conditions. These studies showed that starch synthesis can ...
Improving the short‑term efficiency of rock phosphate‑based fertilizers in pastures by using edaphic biostimulants
(Springer, 2016)
info:eu-repo/semantics/article,
Background: The use of reactive rock phosphate (RP) in acidic soils as a phosphate (P) source for pastures and crops presents attractive economic advantages with respect to soluble phosphate. However, some studies have ...
