摘要:
为了研究外源褪黑素对盐胁迫后苦菜的影响，选择对幼苗生长发育、光合色素影响显著的NaCl溶液作为盐胁迫处理，然后使用不同浓度的外源褪黑素对幼苗作用，检测苦菜幼苗的生长发育、光合色素、抗氧化酶、膜质及渗透调节物等指标。结果表明，0.3 mol/L NaCl溶液对苦菜幼苗有显著胁迫效应，其根长、叶长、鲜质量、叶绿素和类胡萝卜素含量均出现显著降低；0~50 μmol/L浓度的外源褪黑素对盐胁迫后苦菜生长发育和叶绿素含量有显著提升作用，浓度大于50 μmol/L后，类胡萝卜素含量显著增加；较低浓度(25 μmol/L)褪黑素处理即可显著降低盐胁迫后苦菜幼苗的丙二醛含量、相对电导率，这2个指标分别降低了4.9%、14.3%；浓度小于75 μmol/L的褪黑素均可提高过氧化物酶(POD)、超氧化物歧化酶(SOD)活性；50 μmol/L褪黑素可显著增加盐胁迫后苦菜幼苗的可溶性蛋白、可溶性糖、脯氨酸含量，分别较对照提高了34.1%、29.5%、36.8%；对不同指标检测值的相关性分析发现，苦菜幼苗生长发育与叶绿素含量、抗氧化酶活性、渗透调节物质含量均呈显著正相关，类胡萝卜素含量、丙二醛含量、电导率与生长发育指标呈现较大程度的负相关。
