And 67. 5% in Xiangnuo 1 and IR50 respectively when they were under chilling for 2days. Chlorophyll fluorescence data showed that the reaction centers with less accumulation of redundant exciting energy and antenna systems in Xiangnuo 1 were less injured under chilling, with higher qP and qNP which were used to dissipate the redundant exciting energy, and protect the reaction centers from chilling injury. Lower qP and higher Ex as well as decreasing qNP in chilling-susceptible cultivars indicated that its reaction centers and antenna systems were damaged severely by chilling, leading to the lower photosynthetic rate.

叶绿素荧光分析的结果表明，低温下湘糯1号PSII反应中心和天线系统受到的伤害轻，反应中心过剩激发能积累少，可藉较高的qP和qNP进行过剩光能的耗散，保护光合机构免受低温伤害，而冷敏感品种qP下降快，Ex增加较多，但qNP却随低温延长而下降，说明它的反应中心和天线系统都受到了严重的低温伤害，导致光合能力下降。
