Agronomic performance of late-season rice in South China

open access: yesPlant Production Science, 2018
Improving rice yields is critical for global food security. China is a major rice-producing country having two rice cropping systems, i.e. single-season rice cropping system and a double-season system with both early- and late-season rice.

Integrated Land Use Change Related Carbon Source/Sink Examination in Jiangsu Province [PDF]

open access: yesLand, 2021
Carbon emission (CE) threatens global climate change severely, leading to the continuous strengthening of the greenhouse effect. Land use changes can greatly affect the ecosystem carbon budget and anthropogenic CE. Based on the land use grids, net ecosystem productivity (NEP), energy consumption-related CE, this study employed various methods to ...

Sink-source and sink-sink relations during reproductive development in Lolium perenne L. [PDF]

open access: yes, 1997
In greenhouse pot trials, L. perenne cv. Barlet plants were labelled with 13C at regular intervals from main spike emergence onwards in order to identify and measure the activity of source and sink organs during seed formation. The source activity of the

Specific features of source-sink relations in alloplasmic hybrid of winter wheat with alien cytoplasm of goatgrass with emphasis on resistance to low temperature stress [PDF]

open access: yes, 2020
We studied the influence of alien cytoplasm of spring goatgrass Aegilops ovata L. on some physiological parameters in winter wheat (Triticum aestivum L.), Mironovskaya 808, under normal conditions and in the case of modified source-sink relations ...

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

open access: yesCrop 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.

Alteration of Wheat Source-Sink Relation by Nitrogen and Spikelet Removal

open access: yesTekirdağ Ziraat Fakültesi Dergisi, 2023
The source and sink relationships determine the amount and distribution of biomass in plants. Field and laboratory experiments were conducted to study the effect of nitrogen rate and spikelet removal on seed yield and germination traits of wheat. The field experiment was conducted employing sink manipulation (no spikelet removal and ½ spikelet removal)

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

open access: yesFrontiers 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 ...
