Under the background of the further development of interdisciplinary research,phytolith morphometries has been one of the most important directions of phytolith research and contributed great progresses on plant classification and ecology,environmental archaeology,and global change and ecological response.Based on the integrated analysis on the published references,this paper worked out the results as followings.Long saddles (oblong concave saddles)from the Bambusoideae have been indicative of bamboo ecology and habitat ecology in Japan and China,while the phytolith morphometries of cuneiform bulliform cells and long saddles have important reference values on the classification of the woody bamboos on the genus level in Xishuangbanna,southwestern China.The morphometries of cuneiform bulliform cells of the Oryzoideae can also effectively distinguish indica rice from sinica/japonica rice,and the combinations of fish-scaled decorations of cuneiform bulliform cells and morphometries of double-peaked glume cells can accurately distinguish the Asian domesticated rice from the common wild rice.The morphometries of dendriform epidermis long cells from the Panicoideae has been successfully used to distinguish the relationship among common millet,foxtail millet and their related species in the Northwest China.The morphometries of spherical scalloped phytoliths in the Cucurbita of Cucurbitaceae revealed the size and relationship among wild species,semi-domesticated species and domesticated species,which confirmed the history of exploitation of a wild species of Cucurbita in the Early Holocene in the lowland areas of South America.The phytolith morphometries of Leymus chinensis and Phragmites australis from Poaceae in Northeast China reflects the physiological and ecological response of terrestrial plants to global changes.It provides an important reference for studying the response of terrestrial ecosystem to global change and paleoenvironmental reconstruction.
