| Abstract: | Fifteen days old seedlings of waterlogging
tolerant (Parkash) and sensitive (Paras) maize genotypes were subjected to
short term waterlogging (18 h) under field conditions. Activities of various
antioxidative and anaerobic metabolism enzymes were investigated in leaf and
root tissues. Superoxide dismutase (SOD) activity increased in leaf tissue
while glutathione reductase (GR) activity was enhanced in leaf as well as root
in both the genotypes. However, tolerant genotype had better induction
capability of SOD and GR in roots in comparison with sensitive genotype.
Catalase activity increased in roots of both genotypes. Waterlogging caused strong
induction in alcohol dehydrogenase activity in the roots of Paras and Parkash
under stress conditions. Aldehyde dehydrogenase activity was significantly
increased only in roots of Parkash in response to waterlogging. In comparison
with sensitive genotype, the tolerant genotype had low H2O2
and malondialdehyde content in roots under stress conditions. The present
studies suggested that tolerant genotype had a greater protective ability due
to higher induced activities of antioxidant and ethanolic fermentation systems
than Paras. |
