Rooting of herbaceous cutting of different passion fruit plant species

The present work was performed at the Fruit Growing Propagation Area of the Plant Production Departament of the Faculdade de Ciências Agrárias e Veterinárias, Universidade Estadual Paulista (FCAV/UNESP), with the objective of verifying the obtainment potencial of passion fruit seedlings by cutting propagation at Passiflora edulis Sims f. flavicarpa Degener and Passiflora alata Dryander commercial species, and at Passiflora giberti N.E.Brown, Passiflora nitida H.B.K. and Passiflora setacea D.C. rootstocks. The trial was conducted under greenhouse condition with 50% of shading and intermittent nebulization chamber conditions. The cuttings were collected from adult plants of the germoplasm bank of the Plant Production Departament of the FCAV/UNESP and others from commercial orchards, like P. edulis f. flavicarpa. The intermediate part of the last growth branches in the growth stage and herbaceous cuttings with 15cm, three nodes and two half leaves were colected on June and October, 2000 and April, 2001. The cuttings were treated with Indolebutyric Acid (IBA) in 500, 1000 e 2000mg.L-1 concentrations and without using IBA (control), and cultivated in plastic trays (40x30x10cm) with vermiculite during 60 days. The rooting percentage was better for P. edulis f. flavicarpa in spring (October) with 76,7% without using IBA (control). P. alata Dryander and P. nitida rooted in different seasons using 500 mg.L-1 of IBA. P. giberti rooted in spring, but without using IBA. The number and lenght of roots was higher in October. The surviving rate, as well as dead cuttings was higher on June 2000. P. setacea did not root.
