The effects of rising atmospheric carbon dioxide on shoot-root nitrogen and water signaling

Frontiers in Plant Science, 2013
Terrestrial higher plants are composed of roots and shoots, distinct organs that conduct complementary functions in dissimilar environments. For example, roots are responsible for acquiring water and nutrients such as inorganic nitrogen from the soil ...

Temporal and spatial variations of carbon isotope signature reveal substantial contribution of bracts and internode assimilates to grain filling of japonica rice

Crop Journal, 2021
Carbon isotope composition (δ13C) of a plant organ is an inherent signature reflecting its physiological property, and thus is used as an integrative index in crop breeding.

Influence of different rootstocks on the vegetative and reproductive performance of Vitis vinifera L. Malbec under irrigated conditions

OENO One, 2011
Aims:Atrial of cv. Malbec grafted to six different rootstocks (Harmony, SO4, 1103 P, 140 Ru, 3309 C and Cereza) and own rooted cv. Malbec (ORMa) was carried out with the aim to study the influence of rootstock on the vegetative and reproductive ...

A note on withdrawal from a two-layer fluid through a line sink in a porous medium [PDF]

, 2008
The steady response of the free surface of a fluid in a porous medium is considered during extraction of the fluid through a line sink. A conformal-mapping approach is used to derive exact solutions to a family of problems in which the line sink is ...

Review on the impact of elevated CO2concentrations on fruit species in the face of climate change

Ciencia y Tecnología Agropecuaria, 2022
Since the industrial revolution, anthropogenic activities have increased atmospheric CO2concentration—one of the major causes of global warming—with a 600 to 700 ppm prediction by the end of this century.

Organic carbon sink dynamics and carbon sink-source balance in global lakes during the Anthropocene [PDF]

The carbon burial and greenhouse gas emissions of lakes are pivotal in the global carbon cycle to offset or accelerate global warming. However, their balance or the magnitude of anthropogenic increase of carbon burial remains uncertain in global lakes ...

Catabolismo de sacarose durante a mobilização do galactomanano e sua importância na estratégia de sobrevivência de plântulas de Sesbania virgata (Cav.) Pers.

Hoehnea
Sementes de Sesbania virgata possuem galactomanano como polissacarídeo de reserva no endosperma. Durante a mobilização, os produtos de degradação são absorvidos pelos cotilédones que, posteriormente, fornecem esse carbono ao eixo embrionário.
