Abstract: For studing on blade tissue structure and its relations to cold resistance of Lonicera maackii ′Changlvqi′,in continuing observing the time recording a fallen leaf for many years,on the basis counting the green scheduled timepredestination′s ,Have carried out observation and comparison analysing structure′s on the blade of Loniceramaackii Canglvqi′.Result is indicated :The anatomic structure of the leaves of Lonicera maackii Changlvqi′and Loniceramaackii waspositively related to cell tease ratio(CTR)-the thickness of palisade to the whole thickness of leaves.Conversely,thecold resistance was negatively related to the ratio of the thickness.The characteristics of cell structure in leaf tissue suggestedthe genetic differences of cold hardiness among Lonicera maackii ′Changlvqi′appeared relatively stable and couldbe a cold tolerance parameter.

Key words: Loniceramaackii′Changlvqi′, Coldhardiness, Bladeanatomicstructure
