Abstract

This study aimed to evaluate the rooting of P. nitida, using two types of cuttings (1 and 2 buds) and four concentrationsof IBA (0, 1000, 3000 and 5000 mg / L) with slow immersion (5 seconds) in order to use them as a passion fruit rootstock . The experimental design was completely randomized in a 4x2 factorial arrangement (IBA concentrations x number of buds on cuttings), four replications of 10 cuttings, total of 320 cuttings. The cuttings were placed in plastic trays containing expanded vermiculite of medium texture, and kept under intermittent nebulization system for 25 days. The IBA doses influenced the survival, the rooting of cuttings and the root number and length. The number of buds did not influence the cutting rooting.
