摘要:
为了探究低温胁迫对不同狼尾草材料幼苗生理特性的影响及综合评价不同材料的抗寒性。本研究采用泥炭土花盆培养法,对采集的14份乡土狼尾草种子发芽后的幼苗进行低温胁迫(25、4、0、-5 ℃)处理,并测定叶绿素含量、类胡萝卜素含量、抗氧化酶活性、丙二醛含量、渗透调节物质含量。采用主成分分析和隶属函数法对14份材料进行抗寒性评价。随低温胁迫的不断加重,供试狼尾草幼苗的叶绿素a、叶绿素b、总叶绿素、可溶性糖和脯氨酸含量以及过氧化氢酶活性呈先升后降的趋势,类胡萝卜素含量呈逐渐增大的趋势,超氧化物歧化酶活性呈逐渐增加的趋势,可溶性蛋白呈先升后降再略升的趋势,而过氧化物酶活性变化趋势不一致。光合作用相关的各指标之间显著正相关。主成分分析结果表明,低温胁迫下狼尾草的光合因子、质膜系统因子、渗透调节因子可作为抗寒性评价的综合指标。隶属函数综合评价D值结果显示,L10材料的抗寒性较强,L4、L1和L2材料的抗寒性相对较弱。采用隶属函数综合评价法所得结果更加准确客观、可靠性高,研究结果可为狼尾草抗寒性评价及耐低温种质资源的筛选提供参考。
