The photosynthetic rate,stomatal conductance and water potential of fourteen exotic garden species in Baotou were measured.The results indicated that the net photosynthetic rate water potential compensation point and the water potential at the critical variety point of stomatal conductance could be considered as the adaptability indexes for trees to water stress.According to the net photosynthetic rate water potential compensation point,the water potential at the critical variety point of stomatal conductance and osmotic potential at the initial loss turgor,the tested species were classified as five kinds by cluster analysis.The drought resistance (from strong to weak) of the tested species was showed as follows: Spiraea×bumalda ‘Gold Mound’; Spiraea×bumalda ‘Gold Flame’,Ligustrum obtusifolium,Acer negundo ‘Kellys Gold’,Philadelphus coronaries ‘Aurea’; Physocarpus opulifolius ‘Darts Gold’,Prunus×cistena ‘Pissardii’,Acer negundo ‘Aureo-marginatum’,Acer negun do ‘Variegatum’; Sambucus racemosa ‘Plumosa Aurea’,Weigela florida ‘Ziye’,Caryopteris×clandonensis ‘Worcester Gold’,Weigela florida ‘Variegata’; Weigela florida ‘Red Prince’.
