Anatomic indexes in leaves of 4 species of Michelia including Michelia platyetala,Michelia tsoi,Michelia foveolata and Michelia maudiae(two-year-old seedling)and the performances in farm were observed and measured.The results showed that the differences of leaf thickness,cutin layer thickness,stockade tissue thickness,sponge tissue thickness,ratio of stockade tissue thickness to sponge tissue thickness,tightness of leaf tissue structure,sedimentation of leaf tissue structure and stoma density were significant,while the differences of the sizes of upper epidermis and lower epidermis were not.The trees with thick cutin layer,high stoma density,thick stockade tissue,high ratio of stockade tissue thickness to sponge tissue thickness, and high sedimentation of leaf tissue structure are of greater drought resistance.Leaf thickness,especially cutin layer thickness and sponge tissue thickness,are three important anatomic indexes of drought resistance.The order of their drought resistance are Michelia platyetala>Michchelia maudiae>Michelia foveolata>Michelia tsoi.

Abstract: Anatomic indexes in leaves of 4 species of Michelia including Michelia platyetala,Michelia tsoi,Michelia foveolata and Michelia maudiae(two-year-old seedling)and the performances in farm were observed and measured.The results showed that the differences of leaf thickness,cutin layer thickness,stockade tissue thickness,sponge tissue thickness,ratio of stockade tissue thickness to sponge tissue thickness,tightness of leaf tissue structure,sedimentation of leaf tissue structure and stoma density were significant,while the differences of the sizes of upper epidermis and lower epidermis were not.The trees with thick cutin layer,high stoma density,thick stockade tissue,high ratio of stockade tissue thickness to sponge tissue thickness, and high sedimentation of leaf tissue structure are of greater drought resistance.Leaf thickness,especially cutin layer thickness and sponge tissue thickness,are three important anatomic indexes of drought resistance.The order of their drought resistance are Michelia platyetala>Michchelia maudiae>Michelia foveolata>Michelia tsoi.
