摘要: 以0,3,6,9 g·L-1异丙隆对大麦品种保大麦1号叶面喷施处理,24 h后分别在-2,0,2℃低温条件下处理4和8 h,随后测定其SOD活性、POD活性、可溶性蛋白质含量、MDA含量、脯氨酸含量、相对电导率和O·-2产生速率,结果表明:低温对各生理生化指标有显著影响,SOD较POD在活性氧清除中作用更大,所用异丙隆浓度并未对大麦产生明显的伤害作用。

Abstract: The aim of this study was to evaluate the effect of isoproturon with different concentrations and low temperature on the physiological and biochemical characteristics of barley in tillering stage. Baodamai No.1 was treated with 0, 3, 6, 9 g·L-1 isoproturon, and SOD activity, POD activity, soluble protein content, MDA content, proline content, relative electric conductivity, and O·-2 producing rate were determined. The results showed that low temperature showed great influence on the physiological and biochemical characteristics of barley, and SOD was more important than POD in reactive oxygen scavenging system. Isoproturon with tested concentration did not produce obvious damage to barley.

Key words: barley, isoproturon, low temperature, physiological and biochemical characteristics
