The ability of extremely low, time‐varying electromagnetic field (EMF) to improve germination efficacy was studied in Foxtail millet (Setaria italica) seeds using response surface methodology. An optimal factorial central composite design was chosen to optimize the EMF with three critical factors, viz. frequency, intensity, and duration. The adequacy of the model and fitness was evaluated by analysis of variance and regression coefficients. This model suggested that the factors, frequency, and intensity had a significant impact on germination. Optimal conditions for germination were observed to be 10 Hz frequency, 30,007 nT intensity, and 30‐min duration with an observed germination percentage of 93.0, and a predicted germination percentage of 92.92. Magneto‐priming was found to increase the germination efficacy (15.66%), shoot length (27.78%), total seedling length (20.30%), seedling dry mass (26.49%), and water uptake (34.48% at 80 min) showing significant output when compared with the control and positive controls. Remarkable improvements were observed in germination parameters such as vigor index‐1 (39.14%), vigor index‐2 (46.28%), speed of germination (27.52%), and emergence index (12.50%). Magneto‐priming was found to reduce the levels of germination‐specific enzymes, viz. α‐amylase, protease, and dehydrogenase, while it enhanced the levels of antioxidant enzymes, viz. catalase (114.63%) and superoxide dismutase (19.62%), triggering fast germination and early vigor of seedlings. This study clearly showed that EMF priming significantly improved the germination effect and other characteristics of Foxtail millet seeds. Bioelectromagnetics. © 2020 Bioelectromagnetics Society

极低功率随时间变化的电磁场对谷子种子(Setaria italica)种子发芽及其他特性的影响。

非常低,随时间变化的电磁场的(EMF),以提高发芽功效的能力在谷子(进行了研究谷子)种子,使用响应面方法。选择最佳阶乘中心复合设计来优化具有三个关键因素的EMF,即。频率,强度和持续时间。通过分析方差和回归系数来评估模型的适用性和适用性。该模型表明因素,频率和强度对发芽有重大影响。观察到的最佳发芽条件是:频率为10 Hz,强度为30,007 nT,持续时间为30分钟,观察到的发芽率为93.0,预测的发芽率为92.92。磁启动能提高发芽效率(15.66%),枝条长(27.78%),幼苗总长(20.30%),幼苗干重(26.49%)和水分吸收(34。与对照组和阳性对照组相比,在80分钟时占48%)显示出显着的产量。萌发参数得到了显着改善,例如活力指数-1(39.14%),活力指数-2(46.28%),发芽速度(27.52%)和出苗指数(12.50%)。发现磁引发可降低发芽特异性酶的水平,即。α-淀粉酶,蛋白酶和脱氢酶,同时提高了抗氧化酶的水平,即。过氧化氢酶(114.63%)和超氧化物歧化酶(19.62%),引发幼苗快速发芽和早期生长。该研究清楚地表明,EMF引发显着改善了谷子种子的发芽效果和其他特性。生物电磁学。©2020生物电磁学会 萌发参数得到了显着改善,例如活力指数-1(39.14%),活力指数-2(46.28%),发芽速度(27.52%)和出苗指数(12.50%)。发现磁引发可降低发芽特异性酶的水平,即。α-淀粉酶,蛋白酶和脱氢酶,同时提高了抗氧化酶的水平,即。过氧化氢酶(114.63%)和超氧化物歧化酶(19.62%),引发幼苗快速发芽和早期生长。该研究清楚地表明,EMF引发显着改善了谷子种子的发芽效果和其他特性。生物电磁学。©2020生物电磁学会 萌发参数得到了显着改善,例如活力指数-1(39.14%),活力指数-2(46.28%),发芽速度(27.52%)和出苗指数(12.50%)。发现磁引发可降低发芽特异性酶的水平,即。α-淀粉酶,蛋白酶和脱氢酶,同时提高了抗氧化酶的水平,即。过氧化氢酶(114.63%)和超氧化物歧化酶(19.62%),引发幼苗快速发芽和早期生长。该研究清楚地表明,EMF引发显着改善了谷子种子的发芽效果和其他特性。生物电磁学。©2020生物电磁学会 发现磁引发可降低发芽特异性酶的水平,即。α-淀粉酶,蛋白酶和脱氢酶,同时提高了抗氧化酶的水平,即。过氧化氢酶(114.63%)和超氧化物歧化酶(19.62%),引发幼苗快速发芽和早期生长。该研究清楚地表明,EMF引发显着改善了谷子种子的发芽效果和其他特性。生物电磁学。©2020生物电磁学会 发现磁引发可降低发芽特异性酶的水平,即。α-淀粉酶,蛋白酶和脱氢酶,同时提高了抗氧化酶的水平,即。过氧化氢酶(114.63%)和超氧化物歧化酶(19.62%),引发幼苗快速发芽和早期生长。该研究清楚地表明,EMF引发显着改善了谷子种子的发芽效果和其他特性。生物电磁学。©2020生物电磁学会 生物电磁学。©2020生物电磁学会 生物电磁学。©2020生物电磁学会
