Abstract
With the methods of waterlogging and subsequent recovery, different responses of reactive oxygen species(ROS) and antioxidant enzymes at the subcellular level of potato(Solanum tuberosum cv. ‘Favorita') tuber mitochondria to anoxia and post-anoxia were investigated. The results showed that the superoxide anion(O2ˉ·) generating rate, the contents of hydrogen peroxide(H2O2) and malondialdehyde(MDA) in tuber mitochondria under anoxia raised at first and then declined, increased by 43.95%, 49.18% and 69.20% respectively at the fi rst day of anoxia compared with the control, and reached the maximum at the third day. Meanwhile the activities of superoxide dismutase(SOD), ascorbate peroxidase(APX) and catalase(CAT) of tuber mitochondria presented the trend of declining-rising-declining, and decreased by 28.35%, 31.48% and 37.36% respectively at the fi rst day of anoxia compared with the control. Similarly, the O2ˉ· generating rate, the contents of H2O2 and MDA, and the activities of SOD, APX and CAT in tuber mitochondria under post-anoxia also increased first and then decreased, and increased by 144.69%, 63.45%, 59.07%, 39.29%, 11.45% and 2.88% respectively for one-day post-anoxia compared with the one-day anoxia. Moreover, the above indexes showed a relatively large change for the different treatment time of anoxic stress and post-anoxia. Above all, the ROS in tuber mitochondria was easier to burst and aggravate the membrane lipid peroxidation under postanoxia than anoxic stress. As a result, the short-term defensive abilities of mitochondrial antioxidant enzymes were enhanced.
