The effects of presowing treatment of red clover seeds with cold plasma (5 and 7 min) and electromagnetic field (10 and 15 min) on plant agronomic performance were studied. Seed treatments stimulated germination and this effect correlated with changes in the balance of seed phytohormones: a decreased amount of abscisic acid and an increased gibberellin/abscisic acid ratio. Experiments performed in rhizoboxes revealed that seed treatments stimulated root growth and root nodulation. Stressor and dose‐specific changes in the amounts of flavonoids important for communication with nitrogen‐fixing strains of rhizobacteria were detected in the root exudates. The results suggest that besides changes in plant's internal processes, the response of plants to seed treatment involves beneficial modulation of plant communication with microorganisms.

用冷等离子体和电磁场进行种子处理可引起红三叶草根系生长动态变化，类黄酮渗出并激活结瘤

研究了冷浆（5和7分钟）和电磁场（10和15分钟）对红三叶草种子的预播处理对植物农艺性能的影响。种子处理刺激了发芽，这种作用与种子植物激素平衡的变化有关：脱落酸的量减少，赤霉素/脱落酸的比例增加。在根瘤菌箱中进行的实验表明，种子处理刺激了根的生长和根瘤。在根系分泌物中检测到对与根瘤菌固氮菌株通讯很重要的黄酮类化合物的应激源和剂量特异性变化。结果表明，除了植物内部过程的变化以外，植物对种子处理的反应还涉及植物与微生物之间的有效通讯调节。
