Kinematic Analysis of Touch-Sensitive Stigma Movement in Campsis Radicans

The dataset contains quantitative measurements from experiments on Campsis radicans (Bignoniaceae) stigmas. It details five distinct movement patterns resulting from the decoupling of mechanical touch and pollen load signals. Findings reveal mechanical touch controls movement velocity while pollen load determines closure outcome, providing insights into signal integration in plant reproductive behavior.

Use Cases

• Modeling stigma closure probability based on pollen grain count
• Analyzing the relationship between mechanical stimulation and angular velocity of stigma movement
• Studying the temporal dynamics of permanent closure relative to pollen load
• Investigating signal integration in plant reproductive behavior using decoupled touch and pollen stimuli

Strengths

• Dataset size is 534,135 bytes, indicating a substantial amount of recorded data.
• Uses high-resolution time-lapse imaging and motion-tracking analysis for quantification.
• License is clearly defined as CC-BY-4.0, facilitating open reuse.

Limitations

• Column names and the exact row count are not specified in the provided metadata.
• The dataset's temporal coverage for the experiments is not explicitly stated.
• The 'Last updated' date of 2026-03-20 is in the future, indicating a potential metadata error.
