In this study, we applied an inductively coupled, radio frequency oxygen plasma to maize seeds and investigated its effects on seedling emergence, plant number at tasseling, and crop yield of maize in realistic field conditions. Maize seeds of seven different hybrids were treated over two harvest years. In addition to plasma-treated seeds, a control sample, fungicide-treated seeds, an eco-layer, and a plasma and eco-layer combination, were planted. Seedling emergence, plant number at tasseling (plants/m), and yield (kg/ha), were recorded. In the first harvest year, results were negatively affected by the presence of an insect pest. In the second harvest year, plant number and yield results were more uniform. In both years, for two and three hybrids, respectively, the highest yield arose from plants from plasma-treated seeds, but the differences were only partially significant. Considering our results, plasma treatment of maize seeds appears to have a positive effect on the yield of the plant.
在这项研究中，我们应用感应耦合射频氧气等离子体处理玉米种子，并在现实的田间条件下研究其对玉米幼苗出苗率、抽穗期植株数和作物产量的影响。在两个收获年中，对七种不同杂交种的玉米种子进行了处理。除了等离子体处理的种子外，还种植了对照样品、杀菌剂处理的种子、生态层和等离子体与生态层的组合。记录了幼苗出苗率、抽穗期（株/米）和产量（千克/公顷）。在第一个收获年，由于存在虫害，结果受到负面影响。在第二个收获年，植株数和产量结果更加均匀。在这两年中，对于两个和三个杂交种，分别来自等离子体处理种子的植株的产量最高，但差异仅部分显著。考虑到我们的结果，玉米种子的等离子体处理似乎对植株的产量有积极影响。
