Thirty days old seedlings of four varieties of maize (Zea mays L.), viz. Laxmi, Suwan, Desla Yellow and Desla Brown were subjected to waterlogging treatment for 24 and 72 h with a view to assess, the metabolic modification. Post-hypoxic studies were also made after placing the waterlogged plants to normal condition for 48 and 96 h. The results obtained on different parameters like chlorophyll, carotenoids, free aminoacids, pyruvate, glycolic acid, reducing sugar and inorganic phosphorous contents revealed that Suwan and Desla Brown were more tolerant to waterlogging than Laxmi and Desla Yellow.
