ABSTRACT:

The objectives of this research were to evaluate the rooting competence of mini-cuttings throughout the four seasons and to estimate the adventitious rooting time of canjerana clones. A clonal mini-garden was established with 11 clones in a closed hydroponic system. Evaluations were performed throughout the four seasons for the number of mini-cuttings produced per mini-stump, percentage of survival and rooting of mini-cuttings, number of roots, average root length, and number of rooted mini-cuttings per mini-stump. Data were submitted to analysis of variance and means were compared. A rooting curve was estimated for clones 10SM05, 12SMI25, and 12SMI43 that exhibited high competence for adventitious rooting. Our results indicated that canjerana clones can be selected for adventitious rooting competence of mini-cuttings during different seasons, and that canjerana mini-cuttings should be cultivated for 63 days in a rooting chamber.

Key words:
clonal mini-garden; vegetative propagation; seasonality; clone production
