Indolebutyric acid on the rooting of Fuchsia spp. cuttings

Ácido indolbutírico no enraizamento de estacas de Fuchsia spp.

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT:

The princess earring is an ornamental plant native to the southern region of Brazil, much appreciated due to the beauty of its outstanding and colorful flowers. This study evaluated the effect of different doses of synthetic auxin indolebutyric acid (IBA) on the rooting of herbaceous cuttings of Fuchsia regia (Vell.) Munz, native species, and Fuchsia hybrida Hort. Ex Siebert & Voss commercial variety ‘General Monk Red Blue’. The experiment was carried out in a greenhouse following a randomized block design with a 2x5 factorial arrangement (two genotypes of Fuchsia x five IBA doses). The IBA doses consisted in the concentrations of 0, 200, 400, 600 and 800 mg.L^-1. Evaluations were performed 20 days after staking. The parameters evaluated were length of the largest root, number of roots per cutting, fresh weight and dry weight of the aerial part and roots. The concentration of 800 mg.L^-1 of indolebutyric acid resulted in greater rooting of the cuttings of both Fuchsia materials tested. Therefore, the use of IBA (800 mg.L^-1) provided better quality rooted cuttings, with greater length and number of roots.

Key words:
princess earring; cutting; plant growth regulator; auxin; ornamental plant
