Propagation of yellow passion fruit seedlings by cutting, grafting and seeds under salt stress

Salinity is one of the most limiting abiotic stresses in global agricultural sector. The objective this study was to evaluate effect irrigation water salinity on initial development P. edulis Sims. seedlings propagated by seeds, grafting and cuttings. Treatments were distributed a completely randomized design, 5 x 3 factorial arrangement, corresponding levels electrical conductivity (0.3 - control, 1.8, 3.3, 4.8, 6.3 dS m-1) propagation methods (seeds, cuttings grafting), with four replicates plant per plot. Fifty days after imposition treatments saline water, height, number leaves, stem diameter, total chlorophyll, stomatal conductance, relative leaf content, consumption, dry matter root, shoot total, root length volume evaluated. increase affected greater intensity growth variables (height, plant) physiological characteristics (stomatal conductance) species Passiflora edulis, regardless method propagation. Seedlings showed better compared other (seeds cuttings). interaction between seeds intensity.
