Physiological and Biochemical Characteristics Study of Salt Tolerance Bahiagrass Callus
摘要
Abstract
[Objective]The research aimed to compare the physiological and biochemical characteristics of salt tolerance bahiagrass callus from the cell level.[Method]Mature seeds of bahiagrass were dealed with different concentrations (0,5,10,15,20 g/L) of NaCl to induce salt tolerance granular callus and the kinds of general callus.And then the changes of water content, membrane permeability, MDA content, POD activity, SOD activity were studied.[Result]The results showed that, with the increase of NaCl concentration, there was an obvious difference in many ways between the salt group bahiagrass callus and callus of the control group.And the water content, MDA content of the former was obviously higher than the latter.The POD activity, SOD activity of the former was also higher than the latter. The proline played an important role in increasing salt-tolerant of bahiagrass callus.[Conclusion]This study laid a good foundation for further screening of salt-tolerant mutant bahiagrass cell line .关键词
