| 摘 要： | 以药用植物甘草为材料.采用砂基培养法培养幼苗,以含有不同浓度的NaCI或NazCO3的营养液对其分别进行不同强度的盐胁迫或碱胁迫处理.结果表明,随盐浓度的增加,甘草渗透及pH调节物质积累.Na+、脯氨酸、柠檬酸含量增加,K+含量下降.在相同Na+]胁强下,碱胁迫下的胁变反应均比盐胁迫强烈.

| Abstract: | Medicinal plant Glycyrrhiza uralensis Fisch was taken as the material. Seedlings of sand-cultured were stressed with different concentration of NaCl and Na2CO3. The results showed that with the increase of concentration of NaCl and Na2CO3,the contents of Na+, proline and citric acid were increased while K+ concentration was decreased. Under the stress of the same concentration of Na+, the stress reaction of alkali stress was more seriously than that of the saline stress. |
