Effect of Cutting Time and Scion Type on Rooting of Acanthus ilicifolius, Codariocalyx motorius, and Citrus medica var. sarcodactylis

This study was conducted to identify appropriate cutting time and cion type on cutting of Acanthus ilicifolius, Codariocalyx motorius, and Citrus medica var. sarcodactylis. Scions were prepared approximately 5 cm length of greenwood, semi-hardwood, and hardwood and immediately planted in 100 x 100 x 65mm rockwool cube May 26 and August 26, respectively. They were cultivated with natural temperature in a greenhouse and irrigated once a day. Eight weeks after planting, rooting percentage and growth of root and shoot were measured. Rooting percentage was highest in greenwood cuttings. A. ilicifolius and C. medica var. sarcodactylis showed the highest rooting percentage (84.7%, 91.7%) in greenwood cuttings at May 26. In contrast, rooting percentage of C. motorius in greenwood cutting on August 26 was the highest with number of 83.3% among all treatments. And those of C. motorius in each treatment were relatively lower than other plants. A. ilicifolius in semi-hardwood cutting on May 26, C. motorius on greenwood cutting on May 26 and C. medica var. sarcodactylis in greenwood cutting on May 26 showed the highest growth response such as length of root and shoot, fresh weight of root and shoot. Regardless of plants, growth of root and shoot tended to be higher in semi-hardwood or greenwood cutting on May 26 among all treatments. Based on this study, greenwood cutting is the most effective method for cutting of those plants. However appropriate cutting time is May for A. ilicifolius and C. medica var. sarcodactylis and August for C. motorius.
