Abstract
The seeds of wheat variety UP 2565 were invigorated with static magnetic fields of 100- and 200-mT intensities for 1 h and hydropriming for 16 h. Seedling vigour and enzyme activities of all invigorated seeds along with untreated control were conducted in the laboratory. Seedling vigour parameters were significantly higher in invigorated seeds than that of untreated seeds. Among invigorated seeds, hydroprimed seeds took minimum time to emerge than magnetically treated seeds. Similarly root length, shoot length, seedling vigour index were also significantly higher in hydroprimed seeds than magnetically treated seeds. The magnetic treatments led to a significant increase in shoot length, root length, seedling dry weight, vigour index and enzyme activity in comparison with untreated seeds. Alpha amylase activity was also 2.7, 1.8 and 1.3 times higher in hydroprimed, 100- and 200-mT static magnetic field treatments, respectively, over untreated seeds. Electrical conductivity of seed leachate was significantly reduced by hydropriming and static magnetic field treatments. At higher magnetic field, seedling vigour and enzyme activity were reduced.
