Abstract
he propagation of Cryptomeria japonica D. Don by small green shoot cuttings was examined in order to obtain a great quantity of clonal materials rapidly from a mother stock. The cuttings, about 5 cm long were collected from 10 year-old stock plant. They were treated with potassium β-indoleacetate in concentration of 0.04, 0.12, 0.20 percent and water control and Kanumatsti was used as rooting media. The treatment of the growth substance was effective to shorten the period and to enlarg the final amount of rooting in this experiment.
