  • 摘要: 为了探究新型化合物五酸钾对酸雨胁迫下植物抗逆性的影响,本实验通过模拟酸雨环境和叶面喷施五酸钾溶液对盆栽茼蒿进行相关处理.结果表明,茼蒿幼苗在pH=3.0酸雨的胁迫下,其相关的生理指标CAT活性、PRO含量、MDA含量、质膜透性及氧自由基产生速率均有着较为显著地提升,而根系活力及叶绿素含量呈现出较为明显地下降趋势;喷施10 mg·L-1五酸钾溶液后,茼蒿幼苗叶绿素含量及根系活力下降的趋势得到缓解,且在部分时间段出现升高趋势,CAT活性、质膜透性、PRO含量、MDA含量和氧自由基产生速率显著降低.喷施10 mg·L-1新型化合物五酸钾溶液可有效改善酸雨胁迫对茼蒿幼苗生理功能产生的伤害,对酸雨胁迫下茼蒿幼苗的损伤起到明显地防护作用.
