Abstract: With the different stem section of Allamanda violacea for cutting，the cutting experiment was carried out，in different seasons and matrix. The results showed that the survival rate of the non-lignification young stem cutting was 0, which was not suitable for cutting propagation materials; the annual lignification stem section of cutting worked best in spring, and the survival rate of the cuttings was 50% in sand matrix, which had 32 roots and 15 cm of the root length in average. The comprehensive experiment data indicated that A. violacea cutting worked best with the annual lignification stem section cutting in the matrix of red clay in spring.
