Abstract:

Taking Calligonum mongolicum as materials,anatomical structures of stems and young stems were examined for a better understanding of the ecological adaptability,and in the meanwhile C.junceum ’s anatomical structures of stems were examined as a control.The results showed that anatomical structures of young stems was different from its stems.C.mongolicum was an excellent plants in Xinjiang desert vegetation in windbreak and sand fixation.Anatomical structures of young stems had changed with the environment specialized,it has 1～2 layer cells which was arranged in the shape of palisade tissue,a layer was arranged in the shape of the cells in the spongy tissue.Both of them had chloroplast and containing mucus cells in the cortex.The special ization of anatomical structure in C.mongolicum reflected the adaptation to special habitat of drought,high temperature environment,and this enabled a plant to differentiate strongly into xeromorphic structure.Therefore,it is of obvious significance in ecological adaptability.
