Abstract
Aims: Little is known about the Arbuscular mycorrhizal Fungi (AMF) inoculation effects on the initial development of Parkia sp. and phosphorus nutritional needs. This study aimed to evaluate the effect of the AMF inoculation in different phosphorus doses on initial Parkia nitida growth of.
Study Design: The study was carried out in a completely randomized design in a 5x2 factorial scheme (5 doses of phosphorus in the absence and presence of AMF inoculation). Inoculation was done by applying 5 ml of inoculum soil containing a mix of spores (70 spores/m) of the species Acaulospora longula, Acaulospora morrowiae, Dentiscutata heterogama and Paraglomus occultum.
Place and Duration of Study: Experiment occurred at the Amazonas Federal Institute of Education, Science and Technology - Campus Lábrea (7°15'02.9"S 64°47'05.5"W) between January 2017 and December 2017.
Methodology: The variables analysed were the Survival Rate (SR), height (h), lap diameter (d), Seedling Quality Index (h/d), leaflet area (LFA), leaflet number (LFN), shoot dry mass (SDM), dry mass of the root (DMR), DMPA/DMR ratio, total dry mass (TDM) and Dickson Quality Index (DQI).
Results: The variables h and h/d were significant (P=.05) for the interaction between factors only for the treatment without inoculation. It was not possible to determine the appropriate phosphorus dose for the Parkia nitida seedlings production. However, aerial part of the seedlings positively responded to the phosphorus doses increase.
Conclusion: Inoculation did not show significant results in the experimental conditions as well as in the phosphorus interaction.
