Abstract: During low temperature treatment at there were decrease of total protein, increase of water soluble protein, accumulation of hydrogen peroxide, rise of catalase activity and increase of constitutive isoenzyme component bands of peroxidase in yellowish seedlings of maize inbreds. The cold resistant inbred line had more total protein,less water soluble protein and hyd ogen peroxide, higher catalase activity and more constitutive isoenzyme bands of peroxidase than cold sensitive inbred line.

Key words: Low temperature stress, Maize inbred, Hydrogen peroxide, Catalase, Peroxidase constitutive isoenzyme
