| 二次通用旋转组合设计盆栽试验,分析比较宁夏10种主栽苜蓿品种苗期在NaCl、水分复合胁迫下体内脯氨酸含量的变化,并对其抗盐、抗旱性进行初步评价。结果表明:NaCl胁迫对各品种体内脯氨酸含量的主效应除陇东和阿尔冈金苜蓿表现为负效应外,其它苜蓿品种均表现为正效应;水分胁迫对各品种的脯氨酸含量均表现为负效应;其单因素效应为:随NaCl胁迫的增加,各品种体内脯氨酸均有先减小,后增大的趋势;随水分胁迫的增加,各品种体内脯氨酸均有增加趋势;其交互效应表现为:NaCl、水分两因素对阿尔冈金、新疆大叶、宁苜1号、内蒙苜蓿和金皇后五个品种体内脯氨酸含量(Y)影响的交互效应不显著;其余五个品种CW301、三得利、陇东苜蓿、朝阳苜蓿和CW200交互作用显著,且均为负交互,交互作用的大小排序为:YCW301=Y陇东苜蓿>YCW200=Y三得利>Y朝阳苜蓿;以脯氨酸含量为主要指标对10个苜蓿品种抗盐、抗旱性初步排序:CW301>CW200>朝阳苜蓿>金皇后>宁苜1号>阿尔冈金>内蒙苜蓿>陇东苜蓿>三得利>新疆大叶。 |
| 英文摘要: |
| An experi ment was conducted to study the free proline trends during seedling stage and give tentative evaluation about their capability to resist water and NaCl stress of ten staple alfalfa varieties in Ningxia with NaCl and water compound stress by using quadratic general spinning design ．The results showed dominant effect of free proline variation on all alfalfa varieties displayed positive effect except Longdong and Algonguin with negative effect in the case of NaCl stress which displayed negative effect in the case of water stress；Single effect displayed in all varieties free proline content increased at first and then decreased in serious NaCl stress and increased in serious drought；As for the interaction effect of water and NaCl on free proline variation five varieties such as CW301、Sanditi、Longdong、Zhaoyang and CW200displayed negative effect significantly with the order as Y CW301＝Ylongdong＞YCW200＝YSanditi＞Y Zhaoyang while the other varieties such as Algonguin 、Xingjiang 、Ningmu No1、Nei meng and Golden Empress displayed no significant to evaluate the resistance of ten staple alfalfa varieties to NaCl and drought according to their free proline content from high to low the following order may be drawn ：CW301＞CW200＞Zhaoyang ＞Golden Empress ＞Ningmu No1＞Algonguin ＞Nei meng ＞ Longdong ＞Sanditi ＞Xingjiang． |
