| 中文摘要: |
| 通过袋栽试验，研究了淹水对番木瓜光合和叶绿素荧光特性的影响。结果表明，淹水降低番木瓜叶片的净光合速率、蒸腾速率、气孔导度、胞间CO2浓度和PSII有效光化学量子产量（YIELD）、光合电子传递速率 (ETR)和光化学荧光淬灭系数 (qP)，提高其非光化学荧光淬灭(qN)值，同时影响其叶绿素荧光诱导曲线。淹水28 h和52 h后，番木瓜叶片的光合作用明显降低，对照和淹水处理之间的气体交换参数和叶绿素荧光参数差异极显著（P<0.01）。 |

| A bag cultivation experiment was conducted to study the effects of water-logging on photosynthesis and chlorophyll fluorescence characters of Carica papaya L.. The results showed that water-logging decreased the net photosynthetic rate, transpiration rate, stomata conductance, the intercellular CO2 concentration and the effective PSⅡ quantum yield(YIELD),electron transport rate(ETR) and photochemical quenching(qP) as well as non-photochemical quenching (qN) increased of Carica papaya L., affected the chlorophyll fluorescence induction curves. The photosynthetic rate in leaves of Carica papaya L. reduced obviously, and the gas change parameters and chlorophyll fluorescence parameters in water-logging treated plants were significantly different from those in the control (p<0.01) after 28h and 52h of water-logging. |
