以超级杂交稻两优培九及其父本9311、母本培矮64S和三系杂交稻组合汕优63为研究材料,采用光合膜人工反应体系和~(32)Pi同位素标记等技术,初步研究了超级杂交稻两优培九剑叶叶鞘的光化学活性.结果表明,两优培九剑叶叶鞘及其叶片光系统Ⅰ还原能力的均值分别比汕优63高6.35和15.31 μmol/(mg·h),光系统Ⅱ放氧活性的均值分别高出6.16和9.89 μmol/(mg·h),且大多数时期达显著或极显著水平;两优培九剑叶叶鞘及其叶片浸出液钙含量均显著或极显著高于汕优63;两优培九剑叶叶鞘及其叶片叶绿体膜上Mg~(2+)-ATPase活性的均值均高于汕优63,大多数时期达显著或极显著水平;两优培九剑叶叶鞘及其叶片循环光合磷...

By using a super high-yielding hybrid rice combination Liangyoupeijiu, its male parent 9311, female parent Pei＇ai 64S and a three-line hybrid rice combination Shanyou 63 as experimental materials, the techniques of an artificial reaction system for photosynthetic membrane, and 32^ Pi isotopic labeling and so on, were used to study the photochemical activities of the flag leaf sheathes for Liangyoupeijiu. The means of PS Ⅰ reducing capacity of the flag leaf sheathes and blades for Liangyoupeijiu were 6.35 and 15.31 μmol/（mg · h） higher tha...
