Rooting of shoots derived from axillary buds was examined to cstablish an efficient shoot culture system of clonal micropropagation in adult tree of Larix leptolepis Gord. (Japanese larch). Nine out of ten shoots induced calli (90%) on their shoot bases. and the two of them formed root primordia with a red pigment (20%) on the calli surface within 5 weeks after culturing on modified Murashige and Skoog (MS) medium supplemented with 1.5μM of indolebutyric acid (IBA) and 1.5μM of naphthaleneacetic acid (NAA). However, the primordia did not elongate actively. The nddition of 10 mM L-phenylalaninc in the MS medium with the aux-ins resulted in the formation of roots at high frequency. about 80% and they elongated actively. Although callus was formed in all the shoots cultured on the medium with L-phenylalanine, it appeared that the callus development was less as compared to the medium without L-phenylalanine. Consequently, the rooting might be associated with the suppression of the induced callus.
