Abstract
The aim of this study is to investigate the effect of rooting promoters on the rooting and growth of Sedum takesimense cuttage. Results of underground part growth after treatment with rooting promoters showed that the numbers of roots after treatment with 250 mg·L-1 indole-3-butyric acid (IBA), 500 mg·L-1 IBA, and 500 mg·L-1 NAA were 8 to 9, and treatments with 500 mg·L-1 IBA and 500 mg·L-1 α-naphthaleneacetic acid (NAA) resulted in the longest root lengths of 5.3 and 5.4 cm, respectively. In addition, the plants treated with rooting promoters had 60% higher rooting percentage than those without the treatment. The rooting percentage of plants treated with 250 mg·L-1 IBA, 500 mg·L-1 IBA, and 500 mg·L-1 NAA, in particular, was 95% or higher for about 5 days, indicating its effectiveness in root development. The aboveground part of S. takesimense plants treated with 250 mg·L-1 IBA, 500 mg·L-1 IBA, and 500 mg·L-1 NAA had a longer plant height, greater number of leaves, and longer and wider leaves than those treated with other treatments. Accordingly, the survival rate of plants treated with 250 mg·L-1 IBA, 500 mg·L-1 IBA, and 500 mg·L-1 NAA was higher than 90%, suggesting well-established roots and excellent growth of the aboveground parts. In addition, the physiological activity of growth was not inhibited even after cuttage treatment, and the maximum photochemical efficiency (Fv/Fm) and NDVI and SR indices were within the normal range, confirming suitable concentrations of rooting promoters for S. takesimense cuttage. Therefore, the treatment with rooting promoters 250 mg·L-1 IBA, 500 mg·L-1 IBA, and 500 mg·L-1 NAA is considered beneficial for the cuttage of S. takesimense, as they resulted in excellent growth and development of roots and showed a positive effect on the growth of the aboveground parts after cuttage.
