AI Technical Summary

Technical Problem

Existing technologies have failed to effectively distinguish pseudo-maturity characteristics caused by physiological changes in the screening of Epimedium seeds, resulting in low screening accuracy and high cross-variety error rate, which affects the quality and efficiency of seed breeding, storage and seedling cultivation.

Method used

By collecting appearance characteristics and physiological indicators at multiple time points, correction parameters are calculated, including the color change rate benchmark, the physiological-appearance correlation coefficient matrix, and the color feature correction factor. The parameters are adjusted to suit the new batch of seeds, and maturity screening is performed based on the adjusted parameters.

Benefits of technology

This improved the accuracy of screening results, ensuring the quality and efficiency of seed breeding, storage, and seedling cultivation, and preventing the misclassification and waste of high-quality seeds and the mixing of unqualified seeds.
