Abstract:
Physiological effects of 9 kinds of garden arbors (Cedrus deodara,Ligustrum compactum,Pinus bungeana,Prunus cerasifera,Ginkgo biloba,Salix babylonica,Sophora japonica,Lagerstroemia indica,Ailanthus altissima) for a period of 15 days natural water stress treatment were tested.It will provide value reference to instruct greening in regions arid and semi-arid areas.The results indicated that in the natural water loss conditions,drought-resistance indexes from 9 arbors were basically the same,with the extent of stress,the relative moisture content and chlorophyll content decreased,the relative permeability of plasma membrane and MDA content increased,free proline increased,but changes in species.Additionally,it was concluded that the order of 9 plants drought resistance strength was: Pinus bungeana,Ailanthus altissima,Prunus cerasifera,Sophora japonica,Ligustrum compactum,Salix babylonica,Ginkgo biloba,Cedrus deodara,Lagerstroemia indica by the method of membership function to comprehensive assessment of the six physiological indicators.
