摘要
用不同浓度的多效唑(PP333)在干旱胁迫前1 d处理金香水梨幼苗,研究干旱胁迫下PP333对其保护效果。结果表明:PP333预处理有效地降低了干旱胁迫下梨叶片的MDA、CAT含量及POD活性的增加程度,并能有效延缓SOD活性的降低。表明PP333预处理可有效减轻干旱对梨引起的自由基伤害,提高梨抗旱能力,以100 mg/L处理的保护效果最好。
PP333 was used to study the protective effect on Jinxiangshui pear seedling one day before drought stress. The results showed that the pre-treatment of PP333 decreased the level of MDA, CAT content and POD activity, elective retarded the decreased of SOD activity in Jinxiangshui Pear seedling under drought stress. The results showed PP333 eould increase the drought resistance of Jinxiangshui Pear seedlings, among the treatments, the protective effect of the treatment 100 mg/L PP333 was the most effective.
