摘要
探讨突变体A846与野生型水稻在叶绿素荧光特性的表现,进而确定两者是否在光系统Ⅱ上出现差异,作为研究突变体A846矮杆原因的依据之一。在水稻开花至完熟期间,利用荧光测定仪测定矮杆鞘包穗突变体A846和野生型植株的叶绿素荧光动力学参数。数据采用SAS分析后得到如下结果:(1)在yield,qP,NPQ三个荧光参数变化曲线上,突变体表现出较野生型前移的现象。(2)在yield,qP,NPQ三个荧光参数上,突变体仅有yield指标与野生型具有显著差异。(3)突变体与野生型在yield指标上显著差异的时期在9月21日至9月26日间;在qP指标上,显著差异情况比较混乱;在NPQ指标上显著差异的时期在9月17至9月26间。突变体A846在光系统Ⅱ与野生型水稻并没有表现出显著性的差异,而光合生理周期却较提前,这是突变体A846提前进入衰老的依据。
In order to clean the mutant-A846 with the wide-type rice difference on PS Ⅱ ,which was the reason of mutant-A846 dwarf. Using fluorescence detector measured chlorophyll fluorescence parameters form rice flowering to mature-fully.The data analysis using SAS-Software and the results of the mutant （A846） compared with wild-type as flowing： （1） On yield, qP, NPQ fluorescence parameters dynamic curve, the mutant show forward than the wild type. （2） On yield, qP, NPQ fluorescence parameters, only the yield indicator, mutant show significant difference with wild-type. （3） Mutant and wild-type yield indicator significant difference from 9/21 to 9/26; qP indicator, the significant difference was chaos; NPQ indicator significant difference from 9/17 to 9/26.The conclusion is that no obvious distinguished with them, but the mutant-A846 went into decrepit earlier than wide-type rice.
