Late Split-Application with Reduced Nitrogen Fertilizer Increases Yield by Mediating Source-Sink Relations during the Grain Filling Stage in Summer Maize. [PDF]
Plants (Basel), 2023 In the North China Plain, the excessive application of nitrogen (N) fertilizer for ensuring high yield and a single application at sowing for simplifying management in farmer practice lead to low N use efficiency and environmental risk in maize (Zea mays

Alterations in Source-Sink Relations Affect Rice Yield Response to Elevated CO2: A Free-Air CO2 Enrichment Study. [PDF]
Front Plant Sci, 2021 To understand the effects of source-sink relationships on rice yield response to elevated CO2 levels (eCO2), we conducted a field study using a popular japonica cultivar grown in a free-air CO2 enrichment environment in 2017–2018.

Biochar Improves Greenhouse Tomato Yield: Source–Sink Relations under Deficit Irrigation
Agronomy, 2023 It is important to evaluate any effects that biochar may have on tomato yield under deficit-irrigation to develop water-saving and yield-increasing best management practices for greenhouse tomato production. For this purpose, greenhouse trials were conducted in 2021 and 2022 with five biochar (B) application rates and three irrigation (W) levels. The B

Corn Grain Weight: Dependence upon Nitrogen Supply and Source-Sink Relations
Kansas Agricultural Experiment Station Research Reports, 2021 Summary From a yield component perspective, final grain yield in corn ( Zea mays L.) is the result of the number of grains per unit area and their final grain weight. The understanding of grain weight parameters, the rate and duration of grain growth, is

Source/Sink Relations of Abscising and Nonabscising Soybean Flowers [PDF]
Plant Physiology, 1984 The partitioning of recently fixed (14)C to setting and abscising flowers within the axillary raceme of ;Clark' isoline E1t soybeans (Glycine max L. Merr) was examined as a function of time after anthesis of individual flowers. In such racemes, the first four flowers showed a 17% abscission while the next four flowers showed 47% abscission.Source/sink ...

Next-generation strategies for understanding and influencing source–sink relations in crop plants
Current Opinion in Plant Biology, 2018 Whether plants are source or sink limited, that is, whether carbon assimilation or rather assimilate usage is ultimately responsible for crop yield, has been the subject of intense debate over several decades. Here we provide a short review of this debate before focusing on the use of transgenic intervention as a means to influence yield by modifying ...

Source–sink relations and responses to sink–source manipulations during grain filling in wheat
Journal of Integrative Agriculture, 2022 The source–sink ratio during grain filling is a critical factor that affects crop yield in wheat, and the main objective of this study was to determine the source–sink relations at both the canopy scale and the individual culm level under two nitrogen (N) levels at the post-jointing stage.

Using plant growth modeling to analyze C source-sink relations under drought: inter- and intraspecific comparison. [PDF]
Front Plant Sci, 2013 The ability to assimilate C and allocate non-structural carbohydrates (NSCs) to the most appropriate organs is crucial to maximize plant ecological or agronomic performance. Such C source and sink activities are differentially affected by environmental constraints.
