We studied the effects of nonthermal plasma (NTP) treatment on various parameters of early germination stages of Pinus nigra seeds. In the experiment, the diffuse coplanar surface barrier discharge (DCSBD) with treatment time periods of 0, 1, 3, 5, 10, 30, and 60 s was used. Changes on the plasma-treated seed surface were studied by attenuated total reflectance-Fourier transform infrared spectroscopy. Seed germination, germination rate, germination index, length of seedling, dry seedling weight, and seedling vigor index I and II were determined in a growth test under laboratory conditions. Various statistically significant effects of seed exposure to DCSBD plasma treatment were recorded. A positive reaction was observed in the germinated seeds after exposure for 1- and 5-s. Longer exposure time periods had a rather inhibitory effect. The performance of forest nurseries of NTP modification of seeds should be evaluated in order to measure the durability of the observed growth characteristics. The potential of NTP treatment on seeds in plant ecology in future is highlighted.

黑松(Pinus nigra Arnold)在扩散共面表面屏障放电等离子体处理后的种子萌发

我们研究了非热等离子体 (NTP) 处理对黑松种子早期萌发阶段的各种参数的影响。在实验中,使用了处理时间为 0、1、3、5、10、30 和 60 秒的扩散共面表面阻挡放电 (DCSBD)。通过衰减全反射-傅立叶变换红外光谱研究等离子体处理过的种子表面的变化。在实验室条件下通过生长试验测定种子发芽率、发芽率、发芽指数、幼苗长度、幼苗干重和幼苗活力指数I和II。记录了种子暴露于 DCSBD 等离子体处理的各种统计显着影响。在暴露 1 秒和 5 秒后,在发芽的种子中观察到阳性反应。较长的暴露时间具有相当的抑制作用。应评估种子 NTP 修饰的森林苗圃的性能,以测量观察到的生长特性的持久性。NTP 处理种子在未来植物生态学中的潜力得到了强调。
