Abstract

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
