This said, noother studies have yet investigated the role that the substrate mayhave on the plant productivity and final fruit quality and/or com-position. Given that the nature of the substrate may play a crucialrole in determining water and nutrient availability for the plant andhence may affect the metabolic pathways involved in the synthesisof specific biochemical compounds, the present study was con-ducted to assess the effect four different substrates (viz. coir fibre,perlite, rock wool and agrotextile) on the final quality and compo-sition of fruit from three different cultivars grown in the Spanishregion of Huelva. Particular attention was given to quantify sug-ars and organic acids as main indicators of strawberry taste as wellas to quantify the concentration of certain secondary metabolites(viz. anthocyanins and ellagic acid) intimately associated with thepotential health-promoting properties (Giné Bordonaba and Terry,2011).
