Cold plasma technology has received significant attention in agriculture due to its effect on the seeds and plants of important cultivars, such as wheat. Due to climate change, wherein increasing temperatures and droughts are frequent, it is important to consider novel approaches to agricultural production. As increased dormancy levels in wheat are correlated with high temperatures and drought, improving the germination and root growth of wheat seeds could offer new possibilities for seed sowing. The main objective of this study was to evaluate the influence of direct (glow) and indirect (afterglow) radio-frequency (RF) oxygen plasma treatments on the germination of two winter wheat varieties: Apache and Bezostaya 1. The influence of plasma treatment on seed surface morphology was studied using scanning electron microscopy, and it was observed that direct plasma treatment resulted in a high etching and nanostructuring of the seed surface. The effect of plasma treatment on germination was evaluated by measuring the germination rate, counting the number of roots and the length of the root system, and the fresh weight of seedlings. The results of this study indicate that the response of seeds to direct and indirect plasma treatment may be variety-dependent, as differences between the two wheat varieties were observed.
冷等离子体技术因其对重要品种（如小麦）的种子和植株的影响而在农业领域受到了广泛关注。由于气候变化，气温升高和干旱频发，因此考虑农业生产的新方法至关重要。由于小麦休眠水平的提高与高温和干旱相关，改善小麦种子的发芽和根系生长可为播种提供新的可能性。本研究的主要目的是评估直接（辉光）和间接（余辉）射频（RF）氧等离子体处理对两个冬小麦品种阿帕奇（Apache）和别佐斯塔亚1号（Bezostaya 1）发芽的影响。使用扫描电子显微镜研究了等离子体处理对种子表面形态的影响，观察到直接等离子体处理导致种子表面出现高度蚀刻和纳米结构化。通过测量发芽率、统计根系数量和根系长度以及幼苗鲜重，评估了等离子体处理对发芽的影响。本研究结果表明，种子对直接和间接等离子体处理的反应可能因品种而异，因为观察到两个小麦品种之间存在差异。
