The effects of cold atmospheric plasma (CAP) of dielectric barrier discharges on the wettability, imbibition and germination ofLeucaena leucocephalawere investigated. It was established that CAP treatment markedly hydrophilized the seed coat, especially at longer treatment times. From the profile of the imbibition curve and visual observation, it was possible to verify that there are two resistance barriers to water penetration: integument surface and region of the macrosclereid cell wall (light line). Although the plasma interacts only in the integument, increasing the density of hydrophilic sites increases the capacity of water absorption, producing enough driving force to overcome the second resistance barrier. The existence of these two barriers changes the three-phase pattern generally observed during seed germination. Despite an increase in imbibition, the plasma treatment conditions used in this work, were not enough to overcome completely the dormancy barrier.

等离子处理的白藜芦醇中的水路

介质阻挡放电的冷大气等离子体（CAP）对植物润湿性、吸湿性和萌发性的影响银合欢进行了调查。已确定 CAP 处理显着使种皮亲水化，尤其是在较长处理时间时。从吸水曲线的轮廓和目视观察，可以验证水渗透存在两个阻力屏障：珠皮表面和大巩膜细胞壁区域（光线）。虽然等离子体仅在珠被相互作用，但增加亲水位点的密度会增加吸水能力，产生足够的驱动力来克服第二个阻力屏障。这两个障碍的存在改变了通常在种子萌发过程中观察到的三相模式。尽管自吸量增加，但这项工作中使用的等离子体处理条件不足以完全克服休眠障碍。
