- 摘要:
- 为探明不同土壤水分条件下调节剂SODM对水稻保护性酶系的影响,测定了水稻结实期叶片中超氧化物歧化酶(SOD)、过氧化物酶(POD)及过氧化氢酶(CAT)的活性,抗坏血酸(ASA)、丙二醛(MDA)、O-2和H2O2含量。结果表明:SODM处理能够显著增加水稻叶片中SOD、POD及CAT活性,使叶片中MDA、O-2和H2O2含量维持在较低水平,减轻水稻被过氧化程度。
- Abstract:
- In order to study the effect of SODM on drought-resistance relative enzymes of rice under different soil water condition,the activity of superoxides dismutase(SOD),peroxidase(POD),catalase(CAT)and the content of ascorbic acid(ASA),malondialdehyde(MDA),O2- and H2O2 were measured.The results indicated that the treatment of SODM could obviously increase the activity of SOD,POD and CAT in rice leaves,and keep the content of MDA,O2- and H2O2 at the low level in rice leaves,reduce the peroxidation of rice.
