摘要
采用田间试验、植株生理生化测定方法,研究了Mn、B营养对黄瓜产量与抗氧化酶活性的影响。结果表明,Mn、B营养具有明显的互作效应,适宜的Mn、B配施可提高黄瓜产量和叶片超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(cAT)、硝酸还原酶(NR)活性以及叶绿素、抗坏血酸(ASA)含量,降低丙二醛(MDA)含量。黄瓜生产能力与超氧化物歧化酶、过氧化物酶、过氧化氢酶、硝酸还原酶活性显著正相关,与丙二醛含量呈显著负相关。
The fieicl experiment was conducted ancl physiological characters were measured to study the effects of manganese and boron nutrition on yield and antioxidant enzymes of cucumber( Cucumis sativus L. ). The results show that there is a remarkable interaction between Mn and B. The combination of Mn and B nutrition at a proper level can increase cucumber yield, activities of superoxide dismutase (SOD), peroxidase ( POD), catalase ( CAT), nitrate reductase ( NR), and contents of chlorophyll, antiscorbutic acid(ASA) ; decrease malondialdehyde( MDA)content. There are a significant positive relationship between productive capability of cucumber and the activities of SOD,POD, CAT, NR, and a significant negative correlation with the MDA content.
