Abstract: Growth performance and cutting breeding of five kinds of tamarisks introduced to Tianjin were studied. The results show that coniferyl tamarisk couldn't live and grow normally in Tianjin, and the introduction was not successful, while Tamarix austromongolica Nakai grew slowly and didn’t blossom in two years, so further acclimatization tests on it are needed. The other three kinds of tamarisk, such as Tamarix ramosissima Ledeb, Tamarix hispida, Tamarix chinensis Lour(big specification), were of higher survival rates and could grow and develop normally under the condition of coastal saline soil in Tianjin, so they can be used as successful introduced tamarisk resources for popularization and application.

Key words: tamarisk, growth performance, introduction, screening test
