Juniperus conferta. J. chinensis var. procumbens and J. chinensis var. sargentii were used in this experiment with Chamaecyparis obtusa for comparison. The numbers of verrucae per cm which appeared on prostrate branches and which probably became roots were O-0.5 (J. conferta) and O〜13.2 (J. chinensis var. sargentii). As expected from these results, the numbers of primary roots per rooted cutting was greater for J. chinensis var. sargentii than for J. conferta, and, except for C. obtusa, the above numbers became greater for larger cuttings. Except for C. obtusa, n/L (n : number of primary roots per rooted cutting ; L : Iength of the principal stem portion inserted into the soil in planting) showed no significant differences with changes in the sizes of cuttings, indicating rooting all round from the principal stem. Therefore, it can be advantageous for the cuttings of plants, having these properties, to be relatively large.
