Abstract:

用含有NaCl的Hoagland培养液处理盐角草(Salicorniaeuropaea)11d。检测其鲜重,干重,离子含量,电导率,溶解性总固体(TDS)含量,超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性及丙二醛(MDA)浓度。结果表明:随着NaCl浓度的增加,盐角草干重和鲜重呈现先上升后下降的趋势,相对电导率、TDS、SOD、POD、CAT及MDA均呈现先下降后上升的趋势,在NaCl溶液浓度为200mmol·L-1左右时,干重和鲜重的值达到最大,电导率、TDS、SOD、POD、CAT、MDA含量达到最小值;500mmol·L-1和800mmol·L-1时,SOD和CAT活性下降,电导率、TDS、POD、MDA含量则急剧上升。由此说明,一定浓度的NaCl溶液促进了盐角草的生长,200mmol·L-1左右是其生长的最适浓度,500mmol·L-1和800mmol·L-1高盐浓度会对盐角草的膜结构、酶系统等造成不同程度的损伤。盐角草主要将Na+、K+积累在地上部,且随着NaCl处理浓度的增大,Na+含量逐渐增加、K+含量逐渐降低,这可能是盐角草调节细胞内离子平衡对抗盐胁迫的一种适应策略。
