Vigor and Viability of Cagaita (Eugenia dysenterica DC.) Seeds Subjected to Different Substrates

Abstract

Cagaita originates from the Brazilian Cerrado and belongs to the Myrtaceae family. It is a fruit tree and widely disseminated in the Brazilian Cerrado, and can reach up to 10 meters high. To obtain quality seedlings it is necessary to use substrates that have physical and chemical properties suitable for plant development. Also, the quality of the substrate is directly related to the proportions and the material that makes up the mixture. The experiment was conducted in a greenhouse at the Federal Institute of Education (IFTO), Science and Technology of Tocantins, Gurupi/TO city, from November 1, 2017, to February 26, 2018. Cagaita (Eugenia dysenterica DC.) seeds taken directly from the fruit were used to perform the experiment, which was collected in the urban region of Peixe - To in October 2017. Six types of substrates were used for the installation of the experiment, which was: Washed Sand; Washed Sand + Coconut Shell + Black Soil + Poultry Manure; Black Soil; Pine Bark + Poultry Manure + 25% Commercial Substrate Plantmax®; Earthworm Humus + Black Soil + 25% Commercial Substrate Plantmax®; 25% Commercial Substrate Plantmax® + Poultry Manure + Black soil + washed sand. The substrates of earthworm humus + Black Soil + 25% commercial substrate Plantmax® and 25% Commercial Substrate Plantmax® + Poultry Manure + Black Soil + Washed Sand provided the highest values of viability and vigor in Cagaita seeds.
