Cold plasma (CP) has a great potential for decontamination or improvement of grain germination. However, disputing results have been reported, as plasma treatment can affect species and varieties of grains in different ways. The differences may be due to the chemical composition of grain pericarps, the structure of the grains and metabolic response mechanisms. CP treatment decreased grain germination rate, speed and activity of α-amylase of buckwheat grains. Such effects on both varieties of wheat grains were present after longer exposure to plasma. Lipid peroxidation was highest in buckwheat grains, whereas wheat grains were less affected. Plasma-treated Gorolka variety exhibited a low level of lipid peroxidation, no different to untreated grains, compared to Primorka grains, where longer treatment triggered higher levels of lipid peroxidation. The response of grains to CP treatment depends on the chemical and structural properties of grains pericarp, as well as plant tolerance to certain abiotic conditions.
冷等离子体（CP）在谷物去污或改善谷物发芽方面具有巨大潜力。然而，已有相互矛盾的结果报道，因为等离子体处理可能以不同方式影响谷物的种类和品种。这些差异可能归因于谷粒果皮的化学成分、谷粒结构和代谢反应机制。CP处理降低了荞麦籽粒的发芽率、发芽速度和α-淀粉酶活性。在长时间暴露于等离子体后，对两个小麦品种都有这样的影响。脂质过氧化在荞麦籽粒中最高，而小麦籽粒受影响较小。与Primorka籽粒相比，经等离子体处理的Gorolka品种脂质过氧化水平较低，与未处理的籽粒没有差异，在Primorka籽粒中，较长时间处理会引发更高水平的脂质过氧化。谷物对CP处理的反应取决于谷粒果皮的化学和结构特性，以及植物对某些非生物条件的耐受性。
