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.

Metabolite Signals Regulate Gene Expression and Source/Sink Relations in Cereal Seedlings [PDF]
Plant Physiology, 1994 Our knowledge of the genetic structures and regulatory mechanisms active during cereal seedling development has increased dramatically in recent years. For this reason, a more integrated view of the molecular aspects of seedling development and physiology is needed. This review presents the Carbon Metabolite Signal Hypothesis, which attempts to explain

Photosynthetica, 2012 Leaf canopy plays a determining role influencing source-sink relations as any change in source activity (photosynthesis) affects sink metabolism. Defoliation (removal of leaves) influences growth and photosynthetic capacity of plants, remobilizes carbon and nitrogen reserves and accelerates sink metabolism, leading to improved source-sink relations.

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 ...

Source-Sink Relations in Maize Mutants with Starch-Deficient Endosperms [PDF]
Plant Physiology, 1982 Partitioning and translocation of photosynthates were compared between a nonmutant genotype (Oh 43) of corn (Zea mays L.) and two starch-deficient endosperm mutants, shruken-2 (sh2) and brittle-1 (bt1), with similar genetic backgrounds. Steady-state levels of (14)CO(2) were supplied to source leaf blades for 2-hour periods, followed by separation and ...

Corn Grain Weight: Dependence upon Nitrogen Supply and Source-Sink Relations
Kansas Agricultural Experiment Station Research Reports, 2021 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 critical to improve our rational design of management practices and breeding strategies.

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