- 摘要:
- 以长期水分利用效率有显著差异的2份结缕草种源Z109和Z054为试材，研究了干旱胁迫对其光合特性和光合响应曲线的影响。结果表明：干旱胁迫下Z109的光合速率、气孔导度、蒸腾速率、胞间CO2 浓度和水分利用效率的变化不显著；而Z054在干旱胁迫下光合速率、气孔导度、蒸腾速率以及瞬间水分利用效率显著下降，胞间CO2浓度显著上升，潜在水分利用效率变化不显著，说明干旱对Z109光合特征影响较小，Z109比Z054更适应干旱胁迫。在干旱胁迫下，2份种源光合响应曲线变化一致，其最大光合速率均下降，而光补偿点和光饱和点均上升。
- Abstract:
- Taking Z109 and Z054 which long-term water use efficiency was significant difference as materials，effects of drought stress on their photosynthetic characteristics and photosynthetic response curve were studied.The results showed that net photosynthetic rate，stomatal conductance，transpiration rate，inter-cellular CO2 concentration and water use efficiency of Z109 did not change significantly；but net photosynthetic rate，stomatal conductance，transpiration rate of Z054 reduced significantly，intercellular CO2 concentration raised significantly，potential water use efficiency did not change significantly.It implied that the impact of drought on Z109 was smaller than Z054，and Z109 was more adaptable to drought compared with Z054.Photosynthetic response curve of two accessions changed dentically，and maximum assimilation rate of Z109 and Z054 raised，but light compensation point and light saturation point reduced.
