Kurzfassung:
The aim of this work was to evaluate under greenhouse conditions, the rooting potential of different wild species of passion fruit using different doses of indolebutyric acid. Herbaceous cuttings of adult plants of Passiflora setacea, P. coccinea, P. amethystina, P. edulis, P. edulis x P. setacea and P. coccinea x P. setacea were collected and treated with doses of 0, 250, 500, 750 and 1000 mgL-1 of IBA, and then planted in trays with moistened substrate and held under intermittent mist. The experimental design was in randomized blocks with 5 replications and 6 x 5 factorial arrangement (six species and five IBA levels) and 6 useful cuttings per experimental unit. The variables observed were rooted living cutting with sprouts (RLCWS), rooted living cutting without sprouts (RLCWOS), living cutting with callus (LCWC), living cutting without callus (LCWOC), total of rooted cuttings (TRC), dead rooted cutting (DRC), dead cutting with callus (DCWC), dead cutting without callus (DCWOC), total of dead cuttings (TDC), cutting with sprouds (CWS), average cuttings with sprouts (ACWS), root dry matter (ROOTDM), sprout dry matter (SPRDM),and total of dry matter (TOTALDM). The P. amethystina species presented better development than other species, showing rooting potential, with 88.67% of cuttings with roots and sprouts. The use of IBA was efficient as the doses were increased, providing a good development for cuttings of the studied species.
