Alleviating effect of extremely low frequency pulsed electric field on drought damage of maize seedling roots

It was found that the dry weight of root increased, activity of SOD was greater; on the other hand, content of MOD decreased. The results indicated that the treatment of ELF-PEF promoted the growth of root. In addition, the ability of drought resistance and removal of free radicals were both enhanced. The damage of drought on root cells was alleviated. The ultra-weak photon emission was also analyzed, both spontaneous and induced biophoton emission increased, which showed that treatment by ELF-PEF improved the ability of self-organization and respiration metabolism of root cells.
