Resumo(s)
An efficient in vitro method was developed to propagate the shoots of mature wild shrubs
of Vaccinium cylindraceum Sm. by axillary bud proliferation on epicormic stems. In the
initial culture, 46.9% of the epicormic buds produced new shoots with juvenile
morphological features. The number of nodes per shoot and the shoot length for explants
which originated from epicormic buds was significantly higher when compared to that of
winter dormant buds but similar when compared to that of seedling buds. The three most distal buds of epicormic twigs produced the best rates of shoot initiation: 87.5% (position 1) to 62.5% (position 3).
