Plasma treatment is increasingly being explored as an effective presowing treatment improving seed germination. This study examines the synergetic effect of the irrigation condition and the physicochemical surface properties of wheat seeds subjected to atmospheric dielectric barrier discharge plasma activation on their water uptake and germination. Extensive surface analysis revealed a remarkably enhanced wettability of plasma‐treated seeds due to the insertion of oxygen‐containing functionalities on their surface. However, long plasma exposures damaged the outermost layers of the pericarp due to a pronounced oxidative etching effect. Although the seed germination capacity was not affected by the plasma treatments, short plasma exposures were shown to enhance water uptake and accelerate seed germination, especially under water‐scarcity conditions.

DBD等离子体处理小麦种子在不同灌溉条件下的理化表面分析和萌发

越来越多地将等离子体处理作为改善种子发芽的有效播种前处理方法进行探索。这项研究研究了灌溉条件和小麦种子经受大气介电势垒放电等离子体活化后对水分吸收和萌发的协同效应。广泛的表面分析表明，由于含氧官能团插入其表面，等离子处理过的种子的润湿性显着提高。然而，长时间的等离子体暴露由于明显的氧化蚀刻作用而损坏了果皮的最外层。尽管种子的发芽能力不受等离子处理的影响，但短时间的等离子暴露可提高水分吸收并加速种子发芽，特别是在缺水条件下。
