摘　　要：通过钠盐对豌豆 (Pisumsativum)萌发时超弱发光影响的比较研究表明 ,在等渗条件下豌豆幼苗受激发光强度顺序为 :Na2 CO3>NaCl>Na2 SO4 ;Na2 CO3盐胁迫对植物的伤害程度高于其他盐类 ;多盐比单盐存在时的毒害小 ,受激发光作用降低。Through analyzing the effect of the Na\|salt solution on the superweak luminescence of pea( pisum) during the germination,it is found that the luminescence intensity of pea was in order of Na\-2CO\-3>NaCl>Na\-2SO\-4 on isopotential basis of salt stress.The multisalt solution was less harmful than single salt solution at plant growth,and stimulated luminescence of plant with multisalt solution was lower.
