| 摘 要： | 研究不同浓度ABA处理对150 mmol/L NaCl胁迫下(水培条件)的2个不同品种紫花苜蓿Medicagosativa(维多利亚、中苜一号)矿质元素和脯氨酸含量的影响。结果表明:NaCl胁迫显著降低紫花苜蓿植物组织根、茎、叶的干质量。盐胁迫下各组织中积累大量脯氨酸,分布情况为叶茎根,外源ABA能显著提高各组织中脯氨酸的含量。且维多利亚紫花苜蓿脯氨酸含量明显高于中苜一号。与NaCl胁迫相比,添加ABA,2个不同品种紫花苜蓿Na+和Mg2+含量均降低,而K+和Ca2+含量增高,且添加浓度为10μmol/LABA时效果最好。

| Abstract: | In the hydroponics conditions,we studied the mineral elements and proline contents of two alfalfa varieties under different exogenous abscisic acid(ABA) concentrations and 150 mmol/LNaCl.The results showed that the dry matters weight of different plant organs decreased significantly in NaCl tolerance.However,proline content accumulated seriously,which appeared differently in organs: leaf >shoot>root.Moreover,accumulations of proline were more significant under the treatment of NaCl+ ABA.And the contents of ... |
