Abstract: To determine their adaptability,the micro-morphological structures of six Paeonia suffruticosa (peony) tree cultivars:Xiangyuban Lijiangfen Lijiangzi from Lijiang of China and WulongpenshengQinlongwomochiShouanhongfrom central plains of China(Zhongyuan) were compared. Results for Zhongyuan cultivars and Lijiang cultivars showed large differences in the cellsmorphology for palisade tissue,in the ratio of spongy tissue to palisade tissue,and in stomatal density. Also,Zhongyuan cultivars had typical anatomical characteristics for drought resistance with highly developed and closely arranged palisade tissue;whereas Lijiang cultivars had degenerated palisade tissue,large intercellular spaces,and a high ratio of spongy tissue to palisade tissue. ForXiangyuban and Lijiangfen,cell morphology and stomatal characteristics,such as stomatal density and size,were similar. However,Lijiangzi was more capable of adjusting its transpiration due to stomatal density. Meanwhile,Lijiangfen had relatively developed palisade cells,most of which were columnar and closely arranged with sparse,small spongy cells. Smaller ratio of spongy tissue to palisade tissue,which has no significant difference in ratio of spongy tissue and palisade tissue and stomatal density with three Zhongyuan cultivars. Zhongyuan cultivars have different resistance of waterlogging with Lijiang cultivars by comparing their leaf anatomical structures. It showed that stomata density and ratio of spongy tissue to palisade tissue were positively correlated with resistance of waterlogging.[Ch,1 fig. 15 ref.]
