| 摘 要： | 在池栽条件下 ,研究了土壤质地对高产冬小麦豫麦 49号旗叶和籽粒中蔗糖代谢及其关键酶活性的影响。结果表明 ,壤土上豫麦 49号旗叶和籽粒中蔗糖含量高 ,其蔗糖磷酸合成酶(SPS)和蔗糖合成酶 (SS)活性也高。相关分析表明 ,3种质地土壤上豫麦 49号旗叶中SPS活性与其蔗糖含量均呈极显著的正相关 ,籽粒中SS活性与其蔗糖含量的相关性也达极显著。可见 ,SPS和SS是控制小麦蔗糖合成与降解的关键酶

| Abstract: | The studies with high yield winter wheat Yumai 49 during grain filling on the condition of pond culture indicated that the sucrose content of flag leaf and kernel of Yumai 49 in the loam soil was higher than that in clay and sandy soil, the activities of SPS and SS were also higher. It also revealed that the activity of SPS in flag leaf was highly significantly correlated with sucrose content, so was the activity of SS in the kernel. All these suggested that SPS and SS were key enzymes that control the sucrose accumulation and degradation. |
