Abstract
Fast growth of global population leads to necessity to intensify agricultural technologies while reducing their environmental impact. New emerging interdisciplinary field of research on cold plasma (CP) and electromagnetic field (EF) applications for agriculture is directed towards exploiting of the potential of plant functional plasticity. Seed stress induced by treatment with CP and EF leads to improved seed germination, seedling growth and other beneficial effects. Successful development of reliable agrobiotechnology based on these findings is ultimately dependent on knowledge of the molecular mechanisms involved in CP or EF induced signal initiation, response regulation and development. However, until now more detailed information on the molecular processes involved in plant response to seed treatments was lacking. We report novel findings important for understanding of CP and EF effects in the context of seed physiology and molecular processes: (1) the extent of the observed effects on seed germination is largerly dependent on seed dormancy status which is characterized by balance between absisic acid, ABA and gibberrelins, GA. Our results showed that seed treatment with CP and EMF induce rapid decrease in ABA/GA ratio in Raphanus sativus seeds, indicating that CP and EMF may be considered as extremely powerful dormancy breaking agents; (2) pre-sowing seed treatments with physical stressors increase EPR signal and modulate H2O2 production in seeds of P. abies, so that CP treatments inhibiting germination induce decrease ROS generation and EF treatments stimulating germination result in increased ROS generation; (3) short time (2-15 min) seed treatments with CP and EF induce substantial changes in the amount of secondary metabolites and antioxidative activity in leaves growing seedlings of E. purpurea, T. pratense and F. esculentum.[...]
