Here we report that non-thermal atmospheric-pressure plasma exposure can improve Brassica juncea (leaf mustard) seed germination rate from 50 % to 98 %. The commercially relevant germination rate was achieved by plasma exposure for only 10 minutes and the effect sustains at least for one month under an appropriate storage condition. Improved germination by plasma exposure was also observed for Brassica rapa subsp. pekinensis (Chinese cabbage) seeds. The plasma device used is simple. No pure gas flow system is necessary and it is easy to handle. A large number of seeds can be treated by simply scaling up the device. Plasma exposure can be a practical method for improving seed germination of crop plants important for agriculture.
在此我们报告，非热大气压等离子体处理可将芥菜种子的发芽率从50%提高到98%。仅通过10分钟的等离子体处理就实现了具有商业相关性的发芽率，并且在适当的储存条件下，这种效果至少可持续一个月。对于大白菜种子，也观察到等离子体处理可提高其发芽率。所使用的等离子体装置简单。无需纯气体流动系统，易于操作。通过简单扩大装置规模就能处理大量种子。等离子体处理可能是一种切实可行的方法，可用于提高对农业至关重要的农作物种子的发芽率。
