Abstract

SALOMAO, LUIZ CARLOS CHAMHUM; PEREIRA, WALTER ESFRAIN; DUARTE, ROBERTA CRISTINA COTTA  and  SIQUEIRA, DALMO LOPES DE. Propagation of Passiflora alata and P. edulis f. flavicarpa by cutting. Rev. Bras. Frutic. [online]. 2002, vol.24, n.1, pp.163-167. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452002000100036.

The vegetative propagation by cutting is one of the techniques that allows to obtain uniform orchards of passion fruit, as well as of rootstocks that increases productivity and, or resistance to pests and diseases. Even so, the information on the best cutting type to be used are not conclusive. With the objective of evaluating the effects of several types of cuttings, as material for seedling formation of passion fruit, an experiment was carried out in the Fruit Science Sector of the Federal University of Viçosa. The factors in study were apical, medium and basal cuttings of the last growth of Passiflora alata Dryand. and P. edulis f. flavicarpa O. Deg. Fifty days after the beginning of the experiment, it were evaluated the rooting percent, the number of roots, the length of the largest root, the mass of dry matter of the root system, the length and the area of the root system, and the mass of dry matter of the shoot. Cuttings of the basal and medium positions presented bigger rooting potential and larger growth of the root system. Although they have not differed with relationship to the rooting percent and the number of roots, Passiflora alata presented more vigorous root system than P. edulis f. flavicarpa.

Keywords : Passiflora alata; P. edulis f. flavicarpa; vegetative propagation.
