Seed modification by atmospheric pressure non-thermal plasma treatment was tested on pine species. The Diffuse Coplanar Surface Barrier Discharge (DCSBD) with expose times of 0 s, 1 s, 3 s, 5 s, 10 s, 30 s, 60 s was used on seed treatment of Pinus sylvestris , Pinus nigra and Pinus mugo . The effect of plasma treatment on the chemical bonds on the seed surface was studied using the Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR). Characteristics of seed germination and early growth were measured. ATR-FTIR surface diagnostics did not show any damage. Changes in the peak intensities indicated the presence of oxygen and nitrogen-containing groups, or a reduction of the lipid layer on the surface. Various statistically significant effects of the three species of seeds treated with DCSBD treatment were recorded. No significant differences were found between control sample and plasma treated ones, but some positive trends were obtained. Positive trends were recorded in germinated and growing seeds of all three species mainly after 3 s exposures. Exposure times from 10 s had an inhibitory effect. Based on the results obtained, it can be recommended that forest nurseries performance of nonthermal plasma modification of seeds should be evaluated to measure the durability of the observed growth characteristics.

三种松树（Pinus）经扩散共面表面屏障放电等离子处理后的发芽改善

通过常压非热等离子体处理对松树物种进行种子改性测试。使用暴露时间为 0 s、1 s、3 s、5 s、10 s、30 s、60 s 的漫共面表面势垒放电 (DCSBD) 对樟子松、黑松和黑松进行种子处理。使用衰减全反射-傅立叶变换红外光谱 (ATR-FTIR) 研究了等离子体处理对种子表面化学键的影响。测量了种子发芽和早期生长的特征。ATR-FTIR 表面诊断未显示任何损坏。峰强度的变化表明存在含氧和含氮基团，或表面脂质层减少。记录了用 DCSBD 处理的三种种子的各种统计显着影响。对照样品和血浆处理样品之间没有发现显着差异，但获得了一些积极的趋势。主要在暴露 3 秒后，所有三种物种的发芽和生长种子均记录到积极趋势。从 10 秒开始的曝光时间具有抑制作用。根据获得的结果，可以建议对种子的非热等离子体改性的森林苗圃性能进行评估，以测量观察到的生长特性的持久性。
