Viability and Vigor of Pitomba Seeds (Talisia esculenta (St. Hil) Radlk) in two Stages of Maturation in the Different Substrates

The socio-economic importance of pitomba fruits in the North and Northeast regions is a concrete fact, however, commercialized are still acquired from extractivism cultivation backyards without any use technology aimed at their production. experiment was carried out greenhouse Federal Institute Education, Science Technology Tocantins city Gurupi - TO, between February 14 June 2, 2019. treatments applied to seeds consisted two stages fruit maturation, which were classified as: ripe collected plant with light brown peel color on ground dark coloration. substrates used were: Black Soil; Washed Sand; Commercial Substrate; Soil + Sand Humus; Sawdust Powder Substrate. highest physiological quality obtained taken harvested plant, where values, ground, when sowed Substrate (92%; 70%), (97%; 73%) substrate (84%; 67%), (90%; 65%) respectively, lower (54%; 50%) (60%; 60%), respectively. seeds, removed sowing substrates: Sand, showed greater vigor viability.
