RESUMO:

The Passifloraceae family has a pantropical distribution, including about 20 genera and 600 species, in Brazil there are four genera, Ancistrothyrsus Harms, Dilkea Mast., Mitostemma Mast. and Passiflora L., with about 161 species, 89 of which are endemic, in addition to a subspecies and three varieties, with Passiflora being the most common genus of the family, in Mato Grosso there are approximately 42 species of Passiflora and 1 variety in this family Passion fruit (Passiflora spp.) with several native species with great ornamental and food potential is included, being Passiflora edulis Sims. one of the few cultivated species, thus requiring studies and knowledge of native species, for this purpose collections of species of the Passifloraceae family were carried out in the northern region of Mato Grosso from April to December 2020, aiming to cover as many species as possible, in the largest possible area, and in the most different types of forest that they occur. After eight field incursions, 43 individuals of five different species were demarcated, being Passiflora miniata Vanderpl., Passiflora cristalina Vanderpl. & Zappi, Passiflora nitida Kunth, Passiflora foetida L. and Passiflora cincinnata Mast., in the municipalities of Alta Floresta, Carlinda and Paranaíta, thus obtaining the following data, in all 364 fruits were collected, presenting the following values as averages: Fruit length in (mm) 41.48; Fruit Diameter (mm) 34.48; showing Length / Day ratio. 1.44; Shell thickness (mm) 3.03; Fruit Mass (g) 22.94; Shell mass (g) 12.04; Pulp Mass (Aryl + seeds) (g) 10.14; Seed weight (g) 1.43; Quantity of seeds 130.36; Pulp yield of 45.02% and soluble solids content (SS = ° Brix) of 14.09. In the making of the stems, AIB (Indolbutyric Acid) was used, in the proportions 0, 250, 500, 750 and 1000 mg / L, where the acid was efficient in the development of roots and the concentration that provided better results than 750 mg / L. Regarding the Passiflora phenology, it was observed that the Passiflora foetida L. species was the one that presented the highest total number of open flowers in the plant, and fruits stuck to the plant being counted 63 flowers and 91 fruits, referring to the Passiflora species flower buds. miniata presented 385, at the height of its flowering period.
