摘要:
以玉米种子为试验材料,用10%聚乙二醇6000(PEG-6000)模拟干旱胁迫,研究不同浓度的硝普钠(50、100、300、500、1000 μmol/L)浸种对玉米种子萌发和幼苗生长的影响。结果表明:干旱胁迫下,玉米种子的发芽势、发芽指数及幼苗的根、茎长和鲜质量显著下降,过氧化物酶(POD)、过氧化氢酶(CAT)和超氧化物歧化酶(SOD)活性均降低,适宜浓度的硝普钠浸种,缓解了干旱胁迫对玉米种子萌发及幼苗生长的迫害,SOD、POD、CAT 活性均升高,MDA含量下降。通过对比几种不同SNP浓度,结果说明,500 μmol/L SNP对PEG模拟干旱胁迫下玉米种子萌发及幼苗的保护效应较为显著。
