Microcutting culture of passionfruit (Passiflora edulis sims f. flavicarpa Deg.)

Abstract:

Passionfruit (Passiflora edulis Sims f. flavicarpa Deg.) is of great importance by its multiple uses as fresh fruit and in agroindustry, because its juice is rich in minerals (calcium and phosphorus) and vitamins (A and C). The objective of the present work was to evaluate the effect of the benziladenine (BA) and the solidifying agents, on the sprout of passionfruit microcuttings. The two concentrations of BA corresponded to 0 and 2 mg/L and the solidifying agents were agar-agar (7 and 9 g/L) and gelrite (2 g/L). After thirty days of culture in all the treatments explants produced 100% of sprouted and rooted explants, being significant differences (P< 0.05) only in the number of buds by explants. Microcuttings growing culture medium with 2 mg/L of BA and solidified with 7 g/L of agar-agar displayed the maximum number of sprout for explant (5, 9). Microcuttings showed a high efficient sprouting demonstrated the potential of this explant for the establishment of a system for in vitro clonal propagation of passionfruit.
