Abstract:The stems and blades of lawn grasses, Zoysia tenuifolia Willd. ex Trin., Paspalum vaginatum Sw. and Cynodon dactylon (L.) Pers., were anatomically studied. The structures of grass stems and blades showed close relation to the grass drought and trampling resistances, and elasticity. Among the three grasses, Z. tenuifolia was the best in drought resistance, trampling resistance and elasticity in terms of the epidermis, bulliform cells, bundle sheath, sclerenchyma of leaf, and the fibrous girdle of stem; C．dactylon was better in drought resistance，but poorer in tram pling resistance and elasticity：whereas P．vaginzttum was the worst in these characters．
