| 摘 要： | 在马铃薯不同生育期控水的条件下,对马铃薯叶片游离脯氨酸含量和叶片水势与不同生育期的抗旱性关系进行了研究。结果表明：马铃薯叶片游离脯氨酸含量相对值、叶片水势相对值与相应品种的抗旱性有显著的相关性。不同时期的抗旱系数越大抗旱性越强,叶片游离脯氨酸含量相对值、叶片水势相对值均随着生育期和控水水平的加强而增大。

| Abstract: | Under controlling water in different potatoes growth periods conditions,the relation between free proline content,water potential in leaves and drought resistance of different growth periods was studied.The results showed that there was significant correlation between the relative values of free proline content and water potential in leaves and drought resistance of corresponding varieties.The larger drought resistance coefficient of different periods,the stronger drought resistance.The relative values of free proline content and water potential in leaves both increased with growth periods delay and strengthening controlling water level. |
