Abstract: The effects of drought stress on the relative permeability of plasma, protective enzyme activity, and osmoregulatory molecules in leaves of four tested spiny species(Paliurus ramosissimus, Poncirus trifoliata, Rosa laevigata, and Pyracantha fortuneana)were studied. Results showed that the drought stress caused cell membrane damaged and membrane permeability of leaf cell increasing. Superoxide dismutase and peroxidase activities increased with light drought stress and declined with severe drought stress. Praline and soluble sugar in the leaves increasedwith drought stress, but the range and process of changes among the four spiny species were different.Through a comprehensive analysis of physiological and biochemical characteristics, drought resistance in the four tested specieswere shown to decrease in the orderof Paliurus ramosissimus Poncirus trifoliata Rosa laevigata Pyracantha fortuneana.[Ch, 5 fig. 2 tab. 12 ref.]
