Propagation of Thornless Blackberries Utilizing Adventitious Shoots from Root Cuttings

Studies were conducted in early 2003 to determine the effect of root source and length on yield of adventitious shoots and plant yield from root cuttings of Arkansas-developed thornless blackberries. In the first study, roots from ‘Arapaho’ and ‘Apache’ plants grown in an aboveground bed containing commercial potting soil were compared to field-grown roots. Bed-grown roots averaged 6.9 shoots p...
