Abstract
An experiment was carried out to investigate whether detached segments of floricanes during winter pruning of erect blackberries could be used as a source of propagating material. Portions of lateral branches from `Arapaho', `Navaho', `Choctaw', and `Shawnee' field-grown plants, subdivided according to their position on the cane (tip, middle, and base), and treated with or without 0.3% IBA in talc were stuck in peat—perlite mix under intermittent mist in greenhouse conditions. Differences in percentage of cuttings rooted occurred only for cultivars; `Arapaho' rooting the highest (99%) and `Shawnee' the lowest (83%). IBA improved volume of roots formed. Cultivar by position interaction effect was evident for volume of roots, percentage survival of cuttings after potting, percentage shoot formation, and dry weight of shoots and roots, with highest values for stem cuttings taken from the middle of canes of `Arapaho' and lowest for basal cuttings of `Shawnee'. `Choctaw' stem cuttings produced the largest shoots regardless of their position or treatment with IBA. These findings suggest that propagation of erect blackberries by floricane stem cuttings is feasible. This work might be useful to plant breeding, either for early collection of pollen or in controlled pollinations.
