| 摘 要： | 对不同耐高温棉花品系叶片的光合特性及其在盛花期高温胁迫下的变化进行了比较研究.结果表明,与敏感品系XYM68和TS18相比,耐高温品系HLY从盛蕾期到结铃盛期的净光合速率、水分利用率、最大净光合速率和表观量子率显著高于其它2个品系,同时具有较低的光补偿点和较高的光饱和点,而在气孔导度、胞间CO2浓度、蒸腾速率和气孔限制... |

| Abstract: | The leaf photosynthetic characteristics and their response to high temperature stress at peak flowering stage were analyzed comparatively among three cotton lines with different high-temperature tolerance in the paper.The results showed that the tolerant line HLY had significant higher net photosynthetic rate(Pn),water use efficiency(WUE),maximum net photosynthetic rate(Pmax),and apparent quantum yield,also had lower light compensation point(LCP) and larger light saturation point(LSP) as compared with those... |
