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 ...
Intensidade tecnológica e sistemas de trabalho de alto desempenho
(Fundaçao Getulio Vargas, 2004) info:eu-repo/semantics/article,
The paper examines the moderating effect that the technological intensity of the environment in which the firm operates exerts in the High Performance Work Systems (HPWS) - firm's operational performance relationship. We ...
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 ...
