The need to develop and use biotechnology tools to improve management and nutritional
techniques in strawberry cultivation are increasing. Based on this, the objective of this study was to test if the
mycorrhizal inoculation changes the agronomic and qualitative performance of strawberry fruits. The
strawberry daughters plants used were of the cultivar Camarosa. The study was carried out in an agricultural
greenhouse, Horticulture Sector of the Faculty of Agronomy and Veterinary Medicine (FAMV) of UPF, in the
city of Passo Fundo, Rio Grande do Sul (RS), Brazil. The experiment was developed and maintained from June
to December 2015.
The treatments consisted of five inoculum:
T1 = no inoculum (control); T2 = Acaulospora morrowiae; T3 = Rhizophagus clarus; T4 = mycorrhizal community; T5 = Claroideoglomus etunicatum. The experimental design was a randomized block with four replicates. Each plot consisted of a bag containing 6 plants spaced 0.15 mx 0.15 m. In the pits of the plants, it was applied, with the aid of syringe and water, about 70 infective propagules of the tested inocula. During the conduction of the experiment the temperature and photosynthetically active radiation (PAR) were monitored in the culture environment. It was evaluated the agronomic and qualitative performance of the fruits and the percentage of mycorrhizal colonization of the plants roots. The data were submitted to analysis of variance and the differences between means were compared by the Tukey test at 5% of probability error. The cultivar Camarosa produced more fruits in October. In September, the month before the one with the best agronomic performance, the mean temperature was 17.7 ºC. The mean PAR recorded in the growing environment was low in relation to crop requirements, throughout the growing period. Fruits produced by plants inoculated with A. morrowiae presented higher values of TSS/TTA ratio in September and October. The percentage of mycorrhizal colonization varied from 26.2% for A. morrowiae to 46.2% for R. clarus. The inoculation of arbuscular mycorrhizal fungi does not alter the production of strawberry fruits. However, when the plants are inoculated with A. morrowiae there is an improvement in the fruit flavor.
A necessidade de desenvolver e usar ferramentas biotecnológicas para melhorar o manejo e
as técnicas nutricionais no cultivo do morangueiro está aumentando. Com base nisso, o objetivo desse estudo
foi testar se a inoculação micorrízica altera o desempenho agronômico e qualitativo de frutos de morangueiro.
As mudas de morangueiro usadas foram da cultivar Camarosa. O estudo foi realizado em estufa agrícola, no
Setor de Horticultura da Faculdade de Agronomia e Medicina Veterinária (FAMV) da UPF, na cidade de Passo
Fundo, Rio Grande do Sul (RS), Brasil. O experimento foi desenvolvido e mantido de junho a dezembro de
2015.
