摘  要:
设计不同浓度的Ca Cl2溶液,在对菠菜(Spinacia oleracea L.)盐胁迫前采用根部浇灌和叶部喷施的方法进行诱导,钙诱导5 d后,对菠菜幼苗再进行150 mmol/L NaCl溶液处理,测定其形态建成和生理生化指标。结果表明,外源钙能显著提高盐胁迫下菠菜的形态建成指标;显著增加可溶性蛋白质和叶绿素含量;显著提高SOD和POD活性;显著降低丙二醛(MDA)和游离脯氨酸含量。当外源钙离子浓度为30mmol/L时,其降低盐胁迫伤害效应的效果较好。

摘  要:
Different concentrations of calcium chloride were used to induce spinach(Spinacia oleracea L.) with root pouring and leaf spraying method before NaCl stress. After 5 days of induction with calcium chloride, 150 mmol/L NaCl stress was used to spinach seedlings. Morphological, physiological and biochemical indexes of spinach seedlings were detected. The results showed that exogenous calcium ions obviously promote the morphogenesis of spinach under salt stress. The soluble protein content, chlorophyll content and SOD and POD activity were improved, while the production of MDA and free proline in the leaves of spinach was significantly reduced. It was indicated that when the concentration of Ca Cl2 was 30 mmol/L, the effect of alleviating salt injury of spinach was the best.
