We investigate a hybrid treatment-consisting of an atmospheric pressure plasma pretreatment, followed by an MHz surface acoustic waves (SAWs) treatment with either de-ionized (DI) water or plasma activated water (PAW)-on mung beans to accelerate the germination process, as mung bean sprout is one of the important food staples. For the early growth rate (after 320 min), we observe that the hybrid treatment with PAW can lead to approximately 217% higher moisture content for the treated beans when compared with that without hybrid treatment. Additionally, the hybrid-treated beans germinate in around 120 min, while the untreated beans germinate only in around 420 min, that is, 3.5-fold faster for treated beans. This can be attributed to the dominant effect of SAW that accelerates stage 1 water absorption process and the effect of direct plasma and PAW that promote stage 2 metabolism process, leading to the enhancement in stage 3 germination process in early growth rate. For the post growth rate (after 24 h), we observe that the hybrid treatment with DI water can lead to an approximately 44.20% in higher moisture and 71.17% in radicle length when compared with untreated beans. Interestingly, the hybrid treatment with PAW, on the other hand, is observed to have an adverse effect on germination after 24 h, that is, approximately 14.51% lower in moisture content and 43.49% lower in radicle length for the hybrid-treated beans with PAW when compared with that with DI water.

通过 MHz 声波和等离子体的混合处理以增强绿豆的种子发芽。

我们研究了一种混合处理——包括大气压等离子体预处理,然后用去离子 (DI) 水或等离子体活化水 (PAW) 对绿豆进行 MHz 表面声波 (SAW) 处理,以加速发芽过程,因为绿豆芽是重要的主食之一。对于早期生长速率(320 分钟后),我们观察到与未进行混合处理的相比,使用 PAW 的混合处理可使处理过的豆的水分含量提高约 217%。此外,经过杂交处理的豆子在大约 120 分钟内发芽,而未经处理的豆子仅在大约 420 分钟内发芽,即处理过的豆子快 3.5 倍。这可以归因于SAW加速第1阶段吸水过程的主导作用和促进第2阶段代谢过程的直接血浆和PAW的作用,导致早期生长速率的第3阶段萌发过程的增强。对于后生长率(24 小时后),我们观察到与未处理的豆相比,使用去离子水的混合处理可导致约 44.20% 的更高水分和 71.17% 的胚根长度。有趣的是,另一方面,观察到用 PAW 的杂交处理对 24 小时后的发芽有不利影响,也就是说,用混合处理的豆子的水分含量降低了约 14.51%,胚根长度降低了 43.49%。 PAW 与去离子水相比。导致早期生长速度在第 3 阶段萌发过程中的增强。对于后生长率(24 小时后),我们观察到与未处理的豆相比,使用去离子水的混合处理可导致约 44.20% 的更高水分和 71.17% 的胚根长度。有趣的是,另一方面,观察到用 PAW 的杂种处理对 24 小时后的发芽有不利影响,即用杂种处理的豆子的水分含量降低约 14.51%,胚根长度降低约 43.49%。 PAW 与去离子水相比。导致早期生长速度在第 3 阶段萌发过程中的增强。对于后生长率(24 小时后),我们观察到与未处理的豆相比,使用去离子水的混合处理可导致约 44.20% 的更高水分和 71.17% 的胚根长度。有趣的是,另一方面,观察到用 PAW 的杂种处理对 24 小时后的发芽有不利影响,即用杂种处理的豆子的水分含量降低约 14.51%,胚根长度降低约 43.49%。 PAW 与去离子水相比。
