Among the different mutagens, methyl methane sulphorate (MMS) significantly inhibited germination, alpha-amylase activity, RNA and amino acid content in both treatments, and substantially increased cell wall permeability. Ethylene glycol (EG) reduced germination and other molecular degradation less than MMS or EMS (Ethyl Methane Sulphonate), but significantly reduced amino acid content. Applying GA to seeds treated for 6 h reversed the mutagens' effects and improved germination percentage and other molecular contents. Mutagen treatment for 12 h could not be reversed by GA treatment
