ABSTRACT:
This invention is a method for asexual reproduction of coniferous trees. It combines in vivo hormone treatments with in vitro tissue culture for multiplication of a clone of the original genotype. The first step is repetitive cytokinin treatment of the living tree, preferably on weekly intervals. This will induce buds or shoots, usually in axillary locations or at the apex of fasciles. These shoots have a morphology typical of juvenile plants or even newly sprouted seedlings. In culture, the buds will give rise to juvenile-like shoots. The shoots or buds are placed in various media to induce growth and further budding. These second order buds are again placed in a growth medium to give rise to shoots that can then be rooted. The method appears unique in its ability to rapidly and inexpensively multiply a large clone of genotypically superior trees of physiologically and morphologically mature age.
