Study on the Relationship between Leaf Anatomical Structure and Drought Resistance of Four Species of Iris

WANG Jun,GAO Yi-ke(Landscape Architecture College of Beijing Forestry University,Beijing 100083)  
Anatomical character of leaves,which include the size of epidermal cells,ply of cutin,characteristics of mesophyll cells,density of stomata,characteristics of stomata,of four species of Iris which were introduced successfully from Qinghai province have been observed by the light microscope and eduction method.The results showed that the rate of volume and area of leaves: I.lactealI.potaniniiI.loczyiI.songarica;ply of cutin:I.songaricaI.potaniniiI.loczyiI.lacteal;I.loczyi and I.songarica belong to sheltering effect,economizer,endurance and tonicity by anatomical character and density of stomata,I.potaninii and I.lacteal belong to sheltering effect,endurance and tonicity.The confirmation was that the four species of Iris were xerophil,which have strongly adaptability for drought environment.
