摘要: 测定池栽条件下小麦强筋品种藁城8901、中筋品种豫麦49号和弱筋品种洛麦1号灌浆期旗叶、旗叶鞘、穗茎、籽粒中蔗糖磷酸合成酶(SPS)、蔗糖合成酶(SS)活性变化的结果表明,3种不同类型小麦品种灌浆期旗叶、旗叶鞘、穗茎、籽粒中SPS和SS活性变化均呈单峰曲线。豫麦49号旗叶、旗叶鞘和籽粒中SPS酶活性较高,而洛麦1号穗茎中SPS酶活性较高。豫麦49号的旗叶、旗叶鞘、穗茎和籽粒中SS活性高于其他两品种,表明豫麦49号和洛麦1号营养器官和籽粒中蔗糖合成和降解代谢比较活跃。

Abstract: Three winter wheat cultivars with different types of qualities,GC8901(strong gluten cultivar),YM49(medium gluten cultivar)and LM1(weak gluten cultivar)were planted in the soil pool,to investigate their dynamic changes of activities of key enzymes involved in sucrose metabolism in leaf,sheath,stem and kernel during grain filling.Main results indicated that the changes of SPS and SS activities in the leaves,sheaths,stems and kernels of three wheat cultivars during grain filling all presented a single-peak curve.SPS activity was higher in flag leaf,flag leaf sheath and kernel of YM49,but it was higher in flag leaf node of LM1.SS activity in flag leaf,flag leaf sheath,flag leaf node and kernel of YM49 was higher than that of the other two cultivars.This showed that sucrose synthesis and degradation metabolism in the nutritive organs and kernel of YM49 and LM1 was active.
