摘 要 ：在不同的低温处理条件下,测定了离体水稻剑叶的叶绿素荧光诱导曲线。结果表明,与玉米、马玲薯叶片所测定的结果相类似,可变荧光(Fv)有不同程度的降低,而低温对总淬灭(P-T)影响不大。可见,在水稻叶片的碳素同化系统中的基质酶对低温不敏感。

Abstract:The chlorophyll fluorescence emission in detached rice flag leaves had been measured at chilling temperature. The results showed the decrease to some extent in the veriable fluorescence (Fv) in rice as similar as in maize and potato plant, however, with a little change in the total quanching (P-T) probabl because of a lower sensitivity of the stroma enzymes in carbon assimilation system in rice to chilling.
