| Abstract/Contents: | "[Objective] To provide theoretical basis for selecting merit cold-tolerance accessions and varieties breeding. [Method] With the variety of Tifway introduced from foreign country as the control, the physiological and biochemical characteristics of four accessions (including Sau02011, Sau9934, Sau9928 and Sau9926) under continuously low temperature stress (5 °C/-5 °C) for nine days were studied. [Result] Under the low temperature stress, contents of the total chlorophyll in all Cynodon accessions decreased, leaf relative electric conductivity rates and contents of MDA and free proline increased, while SOD activites increased first and then decreased. All Cynodon accessions responded actively under low temperature stress, and continuous low temperature induced injury to them to some extent. [Conclusion] Because of their rather high chlorophyll contents, lower increments of relative electric conductivity rates and contents of MDA, and higher SOD activites [activities] under low temperature stress, Sau02011 and Sau9926 were two excellent accessions with stronger cold-tolerance." |
