aize and Soybean seeds were pre-treated with static
magnetic field (SMF) of 200 mT for 1 h to evaluate the
effect of static magnetic field for alleviation of adverse effects
of salt stress on germination and early growth characteristics.
The adverse effect of NaCl induced salt stress was found on
percentage germination and germination related parameters.
Enhanced percentage germination and early seedling growth
parameters (root and shoot length, and vigour indices) under
different salinity levels (0 to 100 mM NaCl) indicated that
magneto priming was more effective in alleviating salinity
stress at early seedling stage of both maize and soybean as
compared to untreated seeds. α- amylase and protease activities
were also higher in SMF treated seeds under both non-saline
and saline conditions. This could have resulted in faster
hydration of enzymes in SMF treated seeds leading to higher
rate of germination. Increased levels of superoxide radical and
hydrogen peroxide was found in germinating magnetoprimed
seeds of maize and soybean, under both the growing conditions.
Enhancement in seed germination and seedling vigour under
both the growing conditions by SMF treatment may be due to the
combined effect of enhanced α- amylase and protease activities
and enhanced levels of free radicals in the seeds. Consequently,
SMF pre-treatment effectively mitigated adverse effects of NaCl
on both maize and soybean.
