Seed Germination and Seedling Growth of Yellow and Purple Passion Fruit Genotypes Cultivated in Ecuador

Seed is a fundamental tool to carry out breeding processes and for the propagation of crops; however, seed generally has low irregular germination. Passion fruit (Passiflora) species are economically important Ecuador, which main exporter passion concentrate in Latin America. Ecuadorian farmers propagate new plants by seeds establish orchards or extend their cultivated area. The objective this research was determine differences germination seedling development with application priming methods five genotypes belonging three different taxa that commercial use Ecuador. used were: INIAP 2009 P10 (P. edulis f. flavicarpa), Gulupa edulis), local germplasms POR1 flavicarpa) PICH1 maliformis). water (control), hydrogen peroxide at 15%, potassium nitrate 1%, PEG 6000 −1.2 MPa, gibberellic acid 500 ppm. results showed there genotype-response depending on method. Nevertheless, Polietilenoglicol (PEG 6000) could be considered as promising method encourage promote growth Passiflora species. More regarding compound carried order depth physiological related its functions improve well production vigorous seedlings.
