摘要:
杜鹃花是具有商业价值的园林植物,干旱胁迫严重影响杜鹃花幼苗的发育和生理生化特性。为探索褪黑素(MT)对干旱胁迫下园林植物杜鹃花幼苗的生长和生理生化特性的影响,以锦绣杜鹃品种为试验材料,采用随机区组设计,以20%浓度的聚乙二醇(PEG-6000)溶液模拟干旱胁迫,设置5个处理,分别为CK(20% PEG-6000+0 μmol/L MT)、T1(20% PEG-6000+50 μmol/L MT)、T2(20% PEG-6000+100 μmol/L MT)、T3(20% PEG-6000+150 μmol/L MT)、T4(20% PEG-6000+200 μmol/L MT)。结果表明,干旱胁迫显著抑制杜鹃花幼苗生长和生物量的积累,降低了光合色素含量和光合作用的能力,加剧了膜质过氧化的程度,减少了渗透调节物质的含量和抗氧化酶的活性,扰乱了内源激素代谢的平衡。通过施用不同浓度褪黑素,显著提高了幼苗的株高、根系长度和叶面积,增加了生物量的积累,提高了光合色素含量和光合作用能力,降低了膜质过氧化损伤,增强了抗氧化酶的活性,保障了内源激素的代谢平衡,且在150 μmol/L MT处理下达到最佳效果,说明适宜浓度的褪黑素可以促进干旱胁迫下杜鹃花幼苗的生长和缓解生理特性的损害,使其具有较强的耐旱性。
