冷等离子体对作物种子处理效应的研究进展

Advances in Cold Plasma Treatment Effects on Crop Seeds

冷等离子体处理作为一种环境友好、操作简单、安全性高的现代农业物理技术,具有较大的研究潜力和应用前景。本文总结了不同压强和放电方式组合下冷等离子体的性质、冷等离子体对作物种子处理效应的研究进展及展望。归纳发现冷等离子体处理能够改变作物种皮结构,提高种子代谢水平,改善作物的表型、产量等生产性能,并在一定程度上提高植株的抗逆能力。目前对冷等离子体处理效应的报道多集中在作物表型和生理层面,对机理的研究仍有待深入。常压室温等离子体(atmospheric and room temperature plasma,ARTP)是一种近年开始应用的新型冷等离子体源,操作条件更为温和可控,处理效应更加稳定高效。相信今后常规冷等离子体及ARTP处理技术会在改善作物农艺性状、提高作物综合品质等方面得到更加广泛的应用。

Cold plasma treatment, as an environmental-friendly, simple-operation, and high-safety modern agricultural physical technique, possesses high research value and great application prospects. In this review, we summarized the properties of cold plasma under different pressure and discharge methods combinations, research process and outlook of the effect of cold plasma on crop seeds. Cold plasma treatment mainly changed seed coat structures, increased the level of seed metabolism and improved the production performance of crops such as phenotypes and yields. To some extent, cold plasma also improved the resistance of plants. However, most of the existing researches were focused on phenotypic and physiological aspects of cold plasma treatment. Figuring out the mechanism of cold plasma treatment still need further study. Atmospheric and room temperature plasma(ARTP) is the latest type of cold plasma source that has been applied in recent years, with more gentle and controllable operating conditions and a more stable and efficient treatment effect. We believe that in the future,conventional cold plasma and ARTP technique will be more widely used in improving agronomic characteristics in crop cultivation and promoting the overall quality of crops.
