NNaHCO_3胁迫下朝鲜接骨木膜脂过氧化和渗透调节物质含量的变化
Plasma-membrane Peroxidation and Osmotic Substances Changes of Sambucus coreana Seedlings Under NaHCO_3 Stress
摘要
Abstract
The effects of different concentrations of NaHCO_3 and different stress time on plasma-membrane per-oxide-tion and contents of osmoregulation substances of Sambucus coreana (Nakai) Kom. Et Alis. Leaves were studied using plotted experimentation. Dramatic increasing of malondialdehyde contents and relative electrical conductivity was detected with the increasing of NaHCO_3 concentration and treatment time, as well as the soluble protein contents; Marked increasing of proline and soluble sugar contents was detected with the increasing of NaHCO_3 concentration. Results suggested that there were relative jarless physiological responses of S. coreana (Nakai) Kom. Et Alis. Under lower NaHCO_3 concentration (1 g · kg~(-1)) , as well as relative slight changing with increasing treatment time, so it could be planted in mild saline-alkali area.关键词
