Source-Sink Characterization and Nitrogen Response in Three Wheat Cultivars

33.2 KB of experimental data from a field study comparing three wheat cultivars (YM1, YM25, ZM27) under two nitrogen application rates. Author Siqi Zhang published the data on figshare in April 2026 under a CC-BY-4.0 license. The study characterizes source-sink traits like leaf area, specific leaf weight, grain-filling rate, and kernel weight to classify cultivars as source-limited or sink-limited.

Use Cases

• Classifying wheat cultivars as source-limited or sink-limited based on physiological traits described in the study.
• Modeling the impact of nitrogen fertilization on source-sink relationships in wheat.
• Analyzing correlations between source capacity traits (leaf area, SPAD duration) and yield components (kernels per spikelet, 1000-kernel weight).
• Comparing grain-filling dynamics (rate, peak onset) across different wheat genotypes.

Strengths

• Data is derived from controlled field experiments with three distinct cultivars and two nitrogen treatments.
• Includes specific physiological measurements such as specific leaf weight (SLW), SPAD duration, and 1000-kernel weight (TKW).
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is very small (33.2 KB), indicating limited scope, likely a summary table rather than raw observations.
• Geographic location and specific time range of the field experiments are not provided.
