What is it about?

This study investigates the use of cold atmospheric plasma for improving the vigor of lentil seeds. By exposing the seeds to a plasma generated in helium, with or without reactive gases like nitrogen or oxygen, we found that germination time was significantly reduced, leading to a time saving of up to 8 hours. The plasma treatment also increased seed coating hydrophilization and water absorption. Importantly, these positive effects were sustained over a 45-day ageing period, demonstrating the potential of using plasma treatment as a sustainable method to enhance seed growth.

Why is it important?

This work is important because it presents a sustainable and effective method for enhancing seed vigor and reducing germination time. Faster germination can lead to more efficient agricultural practices and improved crop yields, benefiting both farmers and consumers. Furthermore, the plasma treatment does not negatively impact germination rates or seed homogeneity, making it a promising technique for seed companies and researchers to consider. The study also paves the way for future research to explore the underlying mechanisms behind these biological effects and to optimize storage conditions for even better results.


The findings of this research open up new opportunities for further investigations in seed treatment and plant growth. Future studies could explore how the plasma treatment affects the seeds' hormonal activities and their rubbery or glassy states, which depend on their water content and ambient temperature. Additionally, optimizing storage conditions (temperature and humidity) might further enhance the sustainability and effectiveness of plasma treatment. Ultimately, this work could contribute to the development of innovative agricultural technologies and practices that improve crop yields and promote sustainable farming.
