| 摘 要： | 用PEG－6000高渗溶液模拟干旱胁迫，研究了干旱胁迫对胡麻累积游离脯氨酸的影响实验结果表明，在相同时间内，干旱胁迫强度越大累积游离脯氨酸量越多；在胁迫强度相同条件下的一定范围内，随着处理时间的延长累积游离脯氨酸量越来越多；最多累积量为对照的11．5倍这一结果与前人在小麦、水稻、高粱等作物上所得结果一致，证明游离脯氨酸是胡麻幼苗的渗透调节物质，累积游离脯氨酸是胡麻幼苗对干旱环境的适应性表现．

| Abstract: | The accumulation of free proline under drought stress was determened with many plants. The results showed that drought sirests with PEG -- 6000 solution increased the free proline content significantly in Linum uisitatissimum .L. cv. Net Ya No. 3. Along with the decrease of osmotic potential of PEG -- 6000 solution, the accumulation of free proline increased. At the same time, along with the delay of treating peroid, the accumulation of free proline increased. |
