| Abstract: | The annual growth pattern of Populus euphratica clones was simulated by Logistic curve and the maximum points of daily growth rate and the duration of fast-growing stage were estimated. The annual growth pattern of Populus euphratica clones was classed into early, fast and later periods. The clonal growth curves were approached by cross cut polynomiad and the differences of growth curves were significant. |
