Effect on Enzyme Activity in Pearl Millet (Pennisetum glaucum L.) Seedlings in Response to Sulphate Based Salinity

The seeds of thirteen varieties of Pearl millet (Pennisetum glaucum (L.)) were evaluated for enzyme activity in response to sulphate base salinity. Sterilized seeds were safely maintain in filter paper lined Petri dishes and irrigated with water or salt solution (00, 40, 80, 120 m.eq/L). Practice was maintained for the filter paper kept moist by periodic additions of salt solution or water for the required treatments. The research carried out on sulphate dominant salinity. Enzymatic study protease and peroxidase activity increased with increase in salinity, while in case alfa amylase activity, it decreased with increasing salinity level. There was significant interacting effect between salinity treatments and varieties of pearl millet with respect to enzyme activities.
