In recent years, cold plasma treatment has emerged as a promising method to positively impact early seed growth. This study aimed to investigate the effects of cold plasma treatment on millet seeds with ambient air plasma discharge at pressures of 100 Pa and power ranging from 40 to 250 W. Results indicated that cold plasma treatment significantly increased radicle length by up to 112.5% (250 W) after 48 h and up to 57% (120 W) after 72 h compared to nontreated plants. The study also found that cold plasma treatment influenced electron transport during the primary phase of photosynthesis, with the effect varying with the power of discharge. However, high levels of discharge resulted in a significantly higher chlorophyll synthesis. These results suggest that cold plasma treatment may be used to reduce plant stress and improve growing properties.
近年来，冷等离子体处理已成为一种有望对种子早期生长产生积极影响的方法。本研究旨在探讨在100 Pa压力和40至250 W功率下，利用环境空气等离子体放电对谷子种子进行冷等离子体处理的效果。结果表明，与未处理的植株相比，冷等离子体处理显著增加了胚根长度，48小时后增加了112.5%（250 W），72小时后增加了57%（120 W）。该研究还发现，冷等离子体处理影响了光合作用初级阶段的电子传递，其效果随放电功率而变化。然而，高放电水平导致叶绿素合成显著增加。这些结果表明，冷等离子体处理可用于减轻植物胁迫并改善生长特性。
