Magnetic field treatments of seeds have shown significant effects on the enhancement of crop growth. Soil moisture stress is the major constraint in the production of the sunflower crop. Therefore, the experiment was conducted to investigate the effect of a 200 mT magnetic field for 2 h on crop growth, and yield of sunflower crops raised from magnetically treated seeds sown under different moisture stress conditions. Results showed that plants from magnetically treated seeds had higher leaf area index, shoot length, number of leaves, chlorophyll content, biomass, 1000-seed mass, and seed yield as compared with untreated. Radiation use efficiency and water productivity were significantly higher in plants raised from magnetically treated seeds than untreated seeds. Crop raised from magnetically treated seeds had 6.2% more seed yield, 7.1% more protein, and oil content as compared with crops raised from untreated seeds. Hence, it may be concluded that exposure of dry sunflower seeds to the static magnetic field of 200 mT for 2 h could be used for improving crop growth and yield under different moisture stress conditions. © 2021 Bioelectromagnetics Society.
磁场处理种子对提高作物生长有显著影响。土壤水分胁迫是向日葵作物生产的主要限制因素。因此，进行了这项实验，以研究 200mT 磁场 2 小时对从磁场处理种子播种的不同水分胁迫条件下生长的向日葵作物的生长和产量的影响。结果表明，与未处理的种子相比，经磁场处理的种子长出的植物具有更高的叶面积指数、茎长、叶片数、叶绿素含量、生物量、千粒重和种子产量。与未处理的种子相比，经磁场处理的种子生长的植物的辐射利用效率和水分生产力显著提高。与未处理的种子相比，经磁场处理的种子长出的作物的种子产量增加了 6.2%，蛋白质增加了 7.1%，油含量也增加了。因此，可以得出结论，将干向日葵种子暴露于 200mT 的静磁场中 2 小时可以用于改善不同水分胁迫条件下的作物生长和产量。 © 2021 生物电磁学学会。
