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。

The allomatric scaling for the wet clonal plants including Phalaris arundinacea Scirpus planiculmis Phragmites australis and Phragmites Jeholensis did not show "1/4-power Rule". The variation of the allometric exponents between vegetative and reproductive ramets was mainly due to the different regulation mechanisms in different development stages. Moreover, the variation of the allometric exponents between plantsin wet or drought environments was the result of the long-time divergent response for ramets to moisture environments.
