Abstract

This study aimed to optimize a mass propagation system for Camellia japonica by evaluating rooting responses to cutting type (hardwood vs. softwood), rooting medium (sand, Kanumatsuchi, and mixed medium), and plant growth regulators treatment (IBA, NAA × 0, 100, 500, 1,000 ㎎·L-1). Rooting performance differed significantly among treatments. In hardwood cuttings, the highest rooting rate (55.6%) was obtained in Kanumatsuchi with IBA or NAA at 1,000 ㎎·L-1. In softwood cuttings, sand medium treated with IBA at 1,000 ㎎·L-1 resulted in the highest rooting rate (75.6%), whereas mixed medium showed severe decay. Root development characteristics differed significantly among treatments. Overall, softwood cuttings exhibited more vigorous root growth than hardwood cuttings, although their rooting percentages tended to be relatively unstable. Considering both rooting percentage and root development traits, the use of softwood cuttings treated with IBA at 1,000 ㎎·L-1 in sand was determined to be the most suitable and reliable method for improving the propagation success of Camellia japonica.
