Yield, chemical composition, and efficiency of use of nitrogen by Marandu grass
(Revista Brasileira de Zootecnia, 2017)
Absorption, distribution and accumulation of nitrogen applied at different phenological stages in southern highbush blueberry (Vaccinium corymbosum interspecific hybrid)
(Elsevier Science, 2018-01-07)
Southern highbush blueberry has an early harvesting and then a long period of vegetative growth until dormancy, compared to highbush and rabbiteye blueberries. Nitrogen requirements could be different because of this ...
Does nitrogen source influence cadmium distribution in Arabidopsis plants?
(Academic Press Inc Elsevier Science, 2020-03)
The purpose of the present work was to study the effect of the nitrogen source (NO3 - vs NH4 +) on cadmium (Cd) uptake, translocation and partition and its associated toxicity in hydroponically-grown Arabidopsis plants. ...
The role of heterocytes in the physiology and ecology of bloom-forming harmful cyanobacteria
(Elsevier Science, 2016-12)
Dolichospermum flos-aquae and Cylindrospermopsis raciborskii are two cyanobacteria species which cause harmful blooms around the world. Both these species share the capacity to fix atmospheric nitrogen in heterocytes (cell ...
Factors that control the spatial and temporal distributions of phosphorus, nitrogen, and carbon in the sediments of a tropical reservoir
(2018-01-01)
The impacts of anthropic activities have had profound effects on the nitrogen (N) and phosphorus (P) cycles in many aquatic ecosystems. We investigated the spatial and temporal distributions of carbon (C), N, and P in the ...
