| 摘 要： | 以两个耐热性不同的菜豆品种85-CT（耐热）和BBL-47（热敏感）为试材，研究其在不同高温胁迫强度下叶绿素a荧光参数的差异，结果表明：两个品种的叶绿素荧光Fv/Fm及Fv/Fo、电子传递速率（ETR）、均随高温胁迫时间延长呈下降趋势，但耐热品种85-CT下降幅度较热敏感品种BBL-47平缓，BBL-47随高温胁迫时间延长，其叶绿素a荧光诱导动力学曲线中的第二峰（M峰）消失。 |

| Abstract: | Two different heat-tolerance varieties of common bean (Phaseolus vulgarize L.var.85-CT&BBL-47) were used to study the difference of chlorophyll a fluorescence induction kinetics under high temperature stress (37℃/27℃).The results showed that the chlorophyll fluorescence Fv/Fm and Fv/Fo as well as electron translate rate (ETR) of the two varieties decreased under high temperature stress, but the decrease in heat tolerance variety (85-CT) were less than in heat sensitive variety (BBL-47) .The second kurtosis(M) of chlorophyll fluorescence induction kinetics disappeared in BBL-47 under high temperature stress. |
| Keywords: | Common bean High temperature stress Chlorophyll a fluorescence parameter |
