摘要:
为探究不同浓度褪黑素对抗旱性不同的2个小麦品种洛旱7号和Quarron生长发育和生理的影响,设置了6个处理,分别为蒸馏水组:0 μmol/L褪黑素处理(CK)、100 μmol/L褪黑素处理(W100)、300 μmol/L褪黑素处理(W300);10%PEG-6000模拟干旱胁迫组:0 μmol/L褪黑素处理(D0)、100 μmol/L褪黑素(D100)、300 μmol/L褪黑素(D300)。结果表明,在干旱胁迫下随着添加褪黑素浓度的升高,洛旱7号的萌发率,叶绿素a、叶绿素b、叶绿素a+b含量以及POD、SOD和CAT活性呈先上升后下降的趋势;Quarron的干重,叶绿素各含量,POD、SOD和CAT活性也呈先上升后下降的趋势,褪黑素浓度为100 μmol/L时叶绿素含量、抗氧化酶活性为最大值。2个品种间表现为Quarron的POD、SOD、CAT活性高于洛旱7号。试验结果表明,小麦受到干旱胁迫后,100 μmol/L褪黑素对干旱胁迫下的小麦萌发率、叶绿素含量、活性酶含量提升具有显著效果。
