Abstract: The one-year-old semi-lignified branches of C. porrectum ct. citral were used as materials to study the effects of various factors on the rooting of C. porrectum cuttings in order to provide theoretical basis and technical support for its asexual reproduction. The results showed that the rooting rate of short branches was 80.21%, which was significantly higher than that of long branches, and the propagation coefficient of short branches was 3.21, which was 4.2 times that of long branches. IBA could significantly promote the rooting rate of short branches. The optimum concentration of IBA was 4000 mg·L⁻¹, and the rooting rate reached 83.34%. Root number, root diameter, root weight and root volume were also better with 4000 mg·L⁻¹ IBA treatment. The mixture medium of vermiculite and pine bark was beneficial to the rooting of short branches, the optimum mixture medium of vermiculite and pine bark was in the ratio of 1:1, and the rooting rate was higher, reaching 83.34%. The cutting time also significantly affected the rooting of short branches. The rooting rate of cutting in May and July was 78.13% and 73.96% respectively, which was significantly higher than that in September (35.42%). Therefore, micro-cuttage technique could be used for cutting propagation of C. porrectum ct. citral, which could significantly improve the propagation coefficient and seedling-raising efficiency.
