植物在逆境胁迫及衰老进程中,体内活性氧的产生能力大于清除能力。相对过量的活性氧影响生物膜和其它生物大分子的结构或功能。超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、过氧化物酶(POD)等内源活性氧清除剂有助于维持体内氧代谢平衡,从而使植
Plants in the process of adversity stress and aging, the production of reactive oxygen species is greater than the scavenging capacity. Relative excess of reactive oxygen species affects the structure or function of biofilms and other biological macromolecules. Endogenous reactive oxygen scavengers such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) contribute to the maintenance of oxygen metabolism in the body,
