Non-destructive origin and ginsenoside analysis of American ginseng via NIR and deep learning.

American ginseng is widely in demand as a famous medicinal herb, but the production conditions affect the content of ginsenosides in American ginseng, which in turn affects its medicinal value. Currently, it remains a challenge to simultaneously identify the origin and ginsenoside content of American ginseng in a non-destructive manner. In this study, we developed a mixed multi-task deep learning network, MMTDL, combined with near-infrared (NIR) spectroscopy, for the origin traceability and total ginsenoside content prediction of American ginseng.

Shallow water seeding cultivation enhances cold tolerance in tobacco seedlings.

Cold stress can impact plant biology at both the molecular and morphological levels. We cultivated two different types of tobacco seedlings using distinct seeding methods, observing significant differences in their cold tolerance at 4 °C. After 12 h cold stress, shallow water seeding cultivation treatment demonstrates a relatively good growth state with slight wilting of the leaves.
