| 摘 要： | 以美早/东北山樱桃(Prunus serrulata G.Don)和美早/马哈利(P. mahaleb L.)为试材，研究淹水过程中褐色木质根呼吸速率和糖酵解末端产物的变化。结果显示，淹水过程中，两种砧木根系呼吸速率呈下降趋势，胁迫至120 h时，东北山樱桃和马哈利的根系呼吸速率分别为淹水前的73.86％和80.71％；二者根系中乙醛和乙醇含量均呈升高趋势，马哈利乙醛含量高于东北山樱桃，而乙醇含量相反；东北山樱桃丙酮酸含量先升后降，马哈利变幅较小；两种砧木乳酸和琥珀酸含量均呈先升后降趋势，东北山樱桃乳酸、琥珀酸含量出现峰值早且含量大于马哈利；苹果酸含量均呈下降趋势，东北山樱桃下降幅度大于马哈利；二者根系中丙氨酸含量均显著升高，马哈利升幅大于东北山樱桃；天冬氨酸和谷氨酸含量皆下降，其中马哈利下降幅度大于东北山樱桃；脯氨酸含量均先升后降，马哈利的峰值延迟且含量更高。两种砧木对淹水胁迫反应存在差异，东北山樱桃呼吸速率下降较快、细胞碱化能力弱，表明其对淹水更敏感。

| Abstract: | Changes of respiratory rate and glycolytic end products in brown lignified roots of sweet cherry, Meizao/Dongbei Shanyingtao(Prunus serrulata G.Don) and Meizao/Mahaleb(P. mahaleb L.), were studied under waterlogging conditions. The results indicated that root respiratory rate of two kinds of rootstocks, Dongbei Shanyingtao and Mahaleb, decreased gradually, and dropped to 73.86％and 80.71％, respectively, after treatment for 120 h. Content of acetaldehyde and ethanol increased obviously. The acetaldehyde content of Mahaleb was higher than that of Dongbei Shanyingtao, while the ethanol content was lower. The pyruvate content of Dongbei Shanyingtao increased initially and then decreased, but that of Mahaleb didn't change much. The content of lactate and succinate in roots of the two kinds of rootstocks increased at first and then decreased, and Dongbei Shanyingtao peaked earlier and higher than Mahaleb. The malate content of Dongbei Shanyingtao more than Mahaleb. The alanine content increased and Mahaleb was higher than that of Dongbei Shanyingtao. Content of aspatate and glutamate decreased obviously and that of Meizao/Mahaleb decreased more. The proline content increased at first and then decreased, and Mahaleb reached the maximum later and proline content was much higher that of Dongbei Shanyingtao. These results suggested that the response of the two kinds of sweet cherry rootstocks to waterlogging was different. Since its respiratory rate decreased more rapidly, and intracellular alkalization ability was lower, Dongbei Shanyingtao is more sentitive to waterlogging than Mahaleb. |
