Infrared thermography accurately predicts Pisum sativum L. seed viability. This method uses temperature data during germination to classify seeds as viable, aged, or dead with high accuracy, enabling rapid assessment.

Area of Science:

  • Agricultural Science
  • Plant Physiology
  • Biotechnology

Background:

  • Seed viability is crucial for agriculture and crop production.
  • Traditional viability testing methods can be time-consuming and destructive.
  • Developing rapid, non-destructive methods for seed viability assessment is essential.

Purpose of the Study:

  • To develop and validate a non-destructive method for assessing Pisum sativum L. seed viability using infrared thermography.
  • To investigate the correlation between seed temperature fluctuations during germination and viability.
  • To establish a classification model for seed viability based on thermal imaging data.

Main Methods:

  • Seeds were subjected to artificial treatments to induce varying levels of viability.

  • Thermal and visible images were captured throughout a five-day germination test.
  • Seed areas were segmented, and average temperatures were extracted to generate temperature curves.
  • Thirteen characteristic parameters from temperature curves were analyzed.
  • Support Vector Machine (SVM) models were employed for classification.

    • Main Results:

    • A 95% classification accuracy was achieved for viable, aged, and dead seeds using full germination data.
    • An SVM model utilizing only the first three hours of germination data achieved 91.67% accuracy.
    • Distinct temperature fluctuation patterns were observed between seeds of different viability levels.

    Conclusions:

    • Infrared thermography is a viable technique for predicting Pisum sativum L. seed viability.
    • The SVM algorithm effectively classifies seed viability based on thermal imaging data.
    • Early-stage germination temperature data can provide reliable indicators of seed viability, enabling faster assessments.
