ROOTING OF BLUEBERRY HARDWOOD CUTTINGS AS AFFECTED BY WOOD TYPE
Difficulty in propagation using cuttings is a factor that limits blueberry expansion. The success of propagation by cuttings depends on the capacity of adventitious root formation of the cultivar and new root system quality. This work aimed to evaluate the effect of branch type on the rooting of hardwood cuttings of the blueberry cultivars Delite, Bluebelle and Briteblue. The plant material used was derived from whip segments originating from the crown and lateral shoots from old canes, with about 7.0 cm length and 5.5 mm diameter, and 6.0 cm and 3.5 mm, respectively. The cultivar Briteblue showed the highest percentage of rooting (60%), while the cultivar Bluebelle had the lowest (35%). The source of cutting wood affected the percentage of cuttings that survived with 81 and 65% of the cuttings from lateral and whip canes rooting, respectively. Therefore, it was concluded that the cultivar Briteblue was easy to propagate with hardwood cuttings and lateral branches provided a high percentage of rooting, independent of the cultivar.
