RESEARCH FOR INFLUENCE TO THE PART OUT OF EARTH OF TURFGRASSES OF COLD SEASON STYLE BY DROUGHT STRESS

The author made a systematic observation to the influence of qualities of the out look of five kinds of cold seasons style under drought stress by soil water potential (SWP). Evaporate rate (ER), leaf growth rate (LGR). related leaf water content (RLWC). Leaf water potential(LWP), and studied the physiological change of water of turfgrasses under drought stress, and provided the theoretic basis for lurfgrass selection and its scientific management in dry area.$$$$
