CONCEPT OF SEED DETERIORATION: REASON, FACTORS, CHANGES DURING DETERIORATION AND PREVENTIVE MEASURES TO OVERCOME SEED DEGRADATION

Seed deterioration is when a seed loses its vigor and eventually viability. viability an important trait that directly influences seedling emergence crop yield. The rate of varies on several factors. Our main aims were to express the methods for testing deterioration, factors influencing aging, stages changes associated with Practical approaches overcome role reactive oxygen species during aging. From this investigation, it can be concluded high temperatures relative humidity hasten degradation seeds. An increase in loss leachate, drop respiration rates ATP production, enzyme activity, organelle structural breakdown are often seen as seeds age. Various cause but probably oxidative damage brought by free radicals (ROS). Protein oxidation, lipid peroxidation, chromosomal abnormalities, DNA all induced ROS, which have critical interactions any macromolecule biological significance. In early imbibition, some repairs may occur, will lose their within short period. retrieved through different priming exogenous application plant growth regulators.
