3种盐胁迫下静乐藜麦种子与幼苗抗逆指标的检测

Detection of Adverse Circumstances Resistance Indexes of Jingle Quinoa Seed and Seedlings Under Three Kinds of Salt Stress

以山西静乐藜麦为实验材料,NaCl、NaHCO3、Na2CO33种盐作为胁迫因子,探究不同盐类对于静乐藜麦生长的影响。结果表明:在设置的盐浓度范围内,3种盐处理的静乐藜麦种子发芽率、株高及鲜重均呈下降的趋势;幼苗生长中,NaCl处理幼苗的脯氨酸含量及CAT活性呈上升趋势,NaHCO3与Na2CO3处理的幼苗则表现出先增后降的特点。不同处理幼苗的MDA含量呈逐渐上升的趋势。3种盐对静乐藜麦胁迫强度:Na2CO3>NaHCO3>NaCl。
