摘要:
分别用不同浓度的NaCl 以及 NaCl+CaCl 2 溶液处理玉米幼苗, 然后测定丙二醛(MDA)含量、脯氨酸(Pro)含量、过氧化物酶(POD)活性等生理指标。结果表明:玉米在 NaCl+CaCl 2 溶液的处理下, 其生长和生理变化与单独 NaCl 溶液处理不同。 在相同浓度的 NaCl 溶液处理下, 喷施 CaCl 2 溶液的玉米幼苗其 MDA 含量低于单独 NaCl 胁迫, 而Pro 含量、POD 活性则高于单独 NaCl胁迫。表明外源CaCl 2 能够降低玉米幼苗的盐害, 提高其耐盐性。
Abstract:
Seedlings of ZeamaysL.were treated with different concentrations of NaCl and NaCl spraying CaCl 2 , thenmeasur-ing physiological indicators such as malondialdehyde (MDA), proline(Pro)content and peroxidase(POD)activity.The re-sults showed that the changes in growth and physiology of Zeamays L.under NaCl spraying CaCl 2 treatment were differentfrom those only under NaCl stress.Under the same NaCl concentration, the MDA content of Zeamays L.treated by CaCl 2were lower than that treated only by NaCl;while the content of proline and peroxidase activity were higher than thoes whichunder NaCl stress only .From the above factors,it could be concluded that CaCl 2 could alleviate NaCl injury in Zeamays L.seedlings.
