Abstract

A pot culture experiment was conducted in kharif with ten lines of maize (Zea mays L.). After 20 days of growth, plants were subjected to waterlogging. Changes in biochemical characters were recorded in 2 cm root apices after 48 and 96 hours of waterlogging. On a average, soluble sugar content initially increased but after 96 hours of waterlogging it decreased. Proline content also followed a similar trend. Free amino acids content increased under waterlogging and the amount further increased with increased waterlogging duration. Soluble protein content initially increased but later on declined after 96 hours of waterlogging. On the other hand alcohol dehydrogenase (ADH) activity increased after 48 hours of waterlogging. Changes in the levels of these traits followed no definite trend in resistant and susceptible lines. However, the resistant lines, viz. Pant 7377 and Pant 7379 registered lesser increase in ADH activity as compared to susceptible lines.
