Abstract:

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值上没有显著差异。盛花期高温胁迫降低了净光合速率、气孔导度和水分利用效率,增强了蒸腾速率和气孔限制值,而对胞间CO2浓度没有明显影响;与处理前相比,敏感品系XYM68和TS18的净光合速率下降显著,气孔导度的降低幅度显著大于HLY,而蒸腾速率增加的强度却显著低于HLY。高温胁迫下,光系统II的最大光化学效率、量子产量和光化学猝灭系数下降,而非光化学猝灭系数增加;3个不同耐高温品系中,TS18的最大光化学效率减少显著,XYM68和TS18的量子产量、光化学猝灭系数降幅显著高于HLY,而非光化学猝灭系数的增加量却显著低于HLY。
