Effects of extended and sudden heat stress on
various physiological and biochemical processes have been
investigated in ten inbred lines of maize (Zea mays L.) at
seedling stage. Among the various parameters studied, a
significant decrease was observed in membrane stability,
chlorophyll fluorescence and chlorophyll concentration
under extended heat stress and sudden heat shock in sensitive
genotypes which indicated their susceptibility to high
temperature. However, heat tolerant genotypes exhibited
less impact on these parameters which could be attributed
to lesser oxidative stress injury. The free radical scavenging
system in heat tolerant genotypes was observed to be
better established as compared to heat sensitive genotypes.
These findings suggested that the genotypes which performed
better both under extended and sudden heat stress
conditions could be partly due to their superior ability to
cope up with oxidative damage caused by heat stress in
maize.
