- 摘要:
- 以“西州密25号”哈密瓜为试材，采取苗期干旱胁迫处理，测定了与抗旱性有关的游离脯氨酸、甜菜碱、可溶性糖、叶绿素、丙二醛（MDA）含量及酶活性的变化。结果表明：“西州密25号”哈密瓜苗期经干旱胁迫后，初期脯氨酸含量变化不大，从第5天开始脯氨酸含量迅速增加，明显高于对照；甜菜碱含量变化幅度不大，但经干旱胁迫处理后的甜菜碱含量始终略高于对照；可溶性糖含量增加，略高于对照，但在胁迫后期，其含量迅速下降；MDA含量随着干旱胁迫时间的延长，其含量增加；初期叶绿素a、胡萝卜素的含量减少，而叶绿素b含量增加，后期三者变化不明显，但都略高于对照；POD、SOD活性大致均呈先降后升的趋势，且在干旱胁迫处理5 d后略高于对照。
- Abstract:
- ‘Xizhoumi No.25’ hami melon was used as materials，change of free proline，betaine，soluble sugar，chlorophyll，malondialdehyde and enzyme activity of melon were tested under drought stress in this study.The results showed that the proline content changed little in the early，but proline content increased rapidly since 5 days and was significantly higher than CK，betaine content changed smoothly and was always higher than CK,soluble sugar content increased in the early and declined in the later，alondialdehyde content increased，chlorophyll a and carotene contents declined in the early and increased in the later，but chlorophyll b was opposite，they did not change obviously in the later and was higher than CK，POD and SOD activity first roughly fell then rose，and were slightly higher than CK after 5 days.
