Abstract:: Several physiological indices of the seedling of Ailanthus altissima were determined after the treatments of different PEG6000 concentration (0,5%,10%,15%,20%). The results showed as the increasing of osmotic stress, the leaf relative water content (RWC), free water content and leaf chlorophyll content reduced obviously, but relative water deficiency (RWD) increased. So the water loss rate increased, but the water holding capacity reduced. Under the treatments of 5%,10%,15% or 20% PEG, leaf cytomembrane relative permeability were as 3.14,3.44,3.38,3.98 times of the CK’s respectively, and proline content increased by 33.23, 42.79 77.65,26.7 μg/g respectively compared to CK. The POD activity raised under osmotic stress.
