Growth and branching habit of rooted cuttings collected from epicormic shoots of Betula pendula Roth

Patterns of shoot growth and branching were studied over two growing seasons in rooted cuttings collected from both epicomric shoots and seedlings of Betula pendula Roth. Epicormic shoots were induced to sprout on stumps and small logs of 5-, IO- and 30.year-old trees. The use of epicormic shoots...
