Resumo: | Tomato plants respond well to potassium fertilization, whose insufficiency leads to a drop in fruit production and quality. On the other hand, the association of growth-promoting fungi (GPF) with roots has been shown to be able to optimize nutrient absorption, which implies lower financial costs and a decreased risk of loss of K applied to the soil. The objective of this study was to investigate the effects of inoculation with GPF and K rates on the postharvest quality of grape tomato hybrid ‘Mascot’ grown in a hydroponic system. The plants were cultivated in a hydroponic drip system using washed and sterilized sand as substrate. They were trained with two stems, leaving three bunches per stem. The experiment was carried out in a split-split-plot arrangement in a completely randomized design with three replicates. Ripe fruits were stored for 30 days in PET containers in storage chambers at a temperature of 25 °C. After 0, 10, 20 and 30 days of storage, five fruits were collected to determine the titratable acidity (TA) and soluble solids (SS), reducing sugars (RS) and vitamin C contents. The K rates provided an increase in the quality attributes. At low K rates, inoculation with GPF led to higher TA, SS, RS and vitamin C values. Inoculation of the plants with GPF improved the postharvest preservation of the fruits, especially when the plants underwent nutritional stress during cultivation. |

Por outro lado, a associação de fungos promotores de crescimento (FPC) com raízes tem-se mostrado capaz de otimizar a absorção de nutrientes, o que implica menor custo financeiro e menor risco de perdas do K aplicado ao solo. O objetivo deste trabalho foi estudar os efeitos da inoculação com FPC e de doses de K na qualidade pós-colheita do minitomate hibrido Mascot cultivado em hidroponia. As plantas foram cultivadas em sistema hidropônico de gotejamento, usando areia lavada e esterilizada como substrato. Foram conduzidas com duas hastes, deixando-se três cachos por haste. O experimento foi realizado em parcelas sub-subdividadas e em delineado inteiramente ao acaso, com três repetições. Os frutos maduros foram armazenados por 30 dias em embalagens PET em câmaras de armazenamento à temperatura de 25°C. Após 0, 10, 20 e 30 dias de armazenamento coletaram-se 5 frutos para determinação do teor de sólidos solúveis (SS), acidez titulável (AT), de açúcares redutores (AR) e vitamina C. As doses de K tiveram efeito crescente nos atributos de qualidade. Em baixas doses de K a inoculação com FPC resultou em maiores valores de SS, AT, AR e vitamina C. A inoculação das plantas com FPC promoveu melhor conservação dos frutos na pos-colheita, especialmente quando as plantas sofreram estresse nutricional durante o cultivo.UEL2022-02-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4159610.5433/1679-0359.2022v43n2p675Semina: Ciências Agrárias; Vol. 43 No. 2 (2022); 675-692Semina: Ciências Agrárias; v. 43 n. 2 (2022); 675-6921679-03591676-546Xreponame:Semina.
