STUDY ON ANATOMICAL STRUCTURE OF LEAVE AND POLLEN MORPHOLOGY OF ARTEMISIA FRIGIDA IN DIFFERENT HABITATS OF INNER MONGOLIA

Morphological and structural characteristics of leaf and pollen of Artemisia frigida in different habitats of inner Mongolia were compared in this paper.The results showed that: The Leaf structure and morphology of dfferent Artemisia frigida populationc all had charalters with high light and water usage efficiency,in addition,they exhibited drought,cold and radiation resistance ability,these structure and morphology charactrors are in harmony wity their growth environment.The pollen morphology of Artemisia Frigidais long-sphericity,external sculpture is acanthaster,and belong to evolutive types.It has no obvious difference in the pollen morphology of Artemisia Frigida in different habitals.
