With different concentrations of polyethylene glycol (PEG6000), the treatment of water stress was simulated: With the decrease of water porential, the germination percentage, speed and index decreased in total and increased at the temperate water stress (-0.2MPa), indicating that A. pedunculata Pall. has drought tolerance in certain extent.

用不同浓度的PEG6000模拟土壤干旱对种子萌发进行人工水分胁迫处理，随着水势下降，种子发芽率、发芽速度、发芽指数及发芽活力呈下降趋势，在轻度水分胁迫下(-0.2MPa)发芽率有所上升，表明长柄扁桃具有一定的抗旱性。
