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 ...

Agronomy, 2020 Potato tuber yields depend on nitrogen (N) supply, which affects source–sink relations. Transcriptome sequencing of the foliar source using a single field trial identified gene expression responsive to 180 kg N ha−1.

Optimized planting density and nitrogen improve grain yield and water productivity in drip-fertigated maize through improved canopy function and source–sink balance [PDF]
Frontiers in Plant ScienceIntroductionBalanced source–sink relations are essential for achieving high maize yield and water productivity, and maintaining post-silking green leaf area is critical for dry matter accumulation and yield formation in maize (Zea mays L.).

Field Crops Research, 2019 Maize (Zea mays, L.) kernel weight (KW) is regulated by the source-sink relationship at the early grain-filling period, when potential kernel size is defined, and at the effective grain-filling period, when final KW is established.

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

Source–sink relations and kernel weight differences in maize temperate hybrids
Field Crops Research, 2006 Maize ( Zea mays L.) kernel weight (KW) response to changes in assimilate availability per kernel during grain filling suggests that plants establish an early kernel sink potential that place them to grow close to a saturating assimilate availability ...

Reconciling canopy light interception and photosynthetic efficiency to optimize source-sink coordination and yield formation in winter wheat [PDF]
BMC Plant BiologyBackground Optimizing the seeding rate is critical for wheat productivity. However, excessive densification often compromises individual photosynthetic efficiency to maximize canopy light interception, creating a trade-off that constrains yield.

How periodic growth pattern and source/sink relations affect root growth in oak tree seedlings. [PDF]
Journal of Experimental Botany, 2006 Seedlings of Quercus pubescens were grown in root boxes to study the growth pattern of the root system in relation to shoot development. Shoot growth was typically rhythmic. Root elongation was also periodic, in contrast to several previous reports on other Quercus species. Both taproot and lateral root elongation were depressed during expansion of the

The Study of Source-Sink Relations by Comparison of Weight and Grain in the Modern and Old Wheat Cultivars [PDF]
Ikufīziyuluzhī-i Giyāhān-i Zirā̒ī, 2017 Seed filling in wheat is controlled by the availability of substrate (source strength), the capacity of the organs to utilize it for seed growth (sink strength).
