不同品种间甘薯抗旱性差异分析
|
摘要
方法:在甘薯块茎膨大期自然干旱条件下,测定甘薯叶绿素、丙二醛、脯氨酸含量和POD活性,比较不同品种甘薯对干旱胁迫的适应性。结果:干旱胁迫下,叶绿素含量明显下降;丙二醛含量总体先呈上升趋势,后出现下降;脯氨酸含量也呈现先上升后下降的趋势;POD活性则明显上升。结论:干旱胁迫下的丙二醛含量与POD活性呈负相关,POD活性增强可能是丙二醛含量下降的主要原因;甘薯品种川9-15-13抗旱性最强,其次是商薯9号和漯薯10号。
Method:The test in sweet potato tuber enlargement stage by natural drought through on sweet potato leaf chlorophyll content,MDA content,proline content and POD activity was measured,many comparison of different sweet potato varieties to drought stress adaptability.Results:under drought stress,the chlorophyll content was decreased;MDA content overall assumes the trend of escalation,appeared to decline after;proline content also showed the trend of first increased and then decreased;and POD activity is significantly increased.Conclusion:under drought stress,the content of malondialdehyde(MDA)and the activity of pod was negatively correlated,the POD activity enhanced,MDA content decreased,which may is one of the main reasons for the MDA content decreased.Experimental materials(Chuan 9-15-13)showed the strongest drought resistance,followed by Shangshu 9 and Luoshu 10.
