Contaminação de sementes de amendoim, inoculadas por Aspergillus secção Flavi, influenciada pelo genótipo, pela área de cultivo e pelos isolados

Abstract

Peanut can be contaminated by Aspergillus section Flavi in the soil before harvest and during drying and storage. The growth of this fungus can reduce germination and cause the death of the embryo. The objective of this work was to evaluate the contamination in peanut seeds inoculated with A. section Flavi influence by genotype, cultivated area and isolate. The experimental design was a 3 (genotypes: IAC 22, BR 1 and Caiapó) x 4 (treatments: without inoculation and three isolates of A. section Flavi) x 2 (cultivated areas: with or without liming) factorial, with four replicates, in a completely randomized experimental design. A. section Flavi did not reduce the percentage of healthy normal seedlings originated from the inoculated seeds of the different peanut types. Peanut seeds of genotype IAC 22 that were produced in an area with liming generated a smaller amount of abnormal seedlings.
