Dipteryx lacunifera seedlings mycorrhizal levels in goat manure

Abstract

The hypothesis tested was the improved growth of castanha-do-gurguéia (Dipteryx lacunifera Ducke) seedlings inoculated with Claroideoglomus etunicatum growing in a substrate formed with goat manure. Ninety days after sowing, we evaluated: plant height, stem diameter, number of leaves, number of leaflets, root length, root diameter, root volume, secondary root numbers, root dry mass, shoot dry mass. The indices of quality seedlings were evaluated the relationship between shoot height and stem diameter, the relationship between shoot dry mass and root dry mass, and the Dickson quality index. Inoculation of the substrate with the isolated Claroideoglomus etunicatum promotes growth and increase in biomass for castanha-do-gurguéia seedlings. The level of 10% of goat manure in sand promoted the growth of castanha-do-gurguéia seedlings.
