Summary

Researchers developed a non-destructive, interpretable deep learning framework using excitation-emission matrix fluorescence spectra of root exudates to detect microplastic stress in rice seedlings at early stages. The approach enables early-warning detection of plastic contamination effects on crop health without damaging the plants.

In summary, this study establishes a novel, non-destructive, and interpretable framework for the early detection of MPs stress in rice seedlings based on EEMF spectra of root exudates combined with deep learning.
