| description | Characteristics of food quality can affect the health of consumers and are influenced by several factors including the system of production. Lettuce has the highest sales volume of any leafy vegetable sold in Brazil and is considered a good source of vitamins, minerals and other compounds. This study aimed to determine the influence of the type of production system (conventional, organic and hydroponic) on the physical and chemical characteristics of two lettuce cultivars. Experiments were conducted simultaneously for each production system using a completely randomized design with three repetitions and two lettuce cultivars (Rubra and Crystal). Subsequently, a joint analysis of the three experiments was performed and averages compared by a Tukey test at 5%. The following characteristics were evaluated: number of leaves, plant height, plant diameter, stem diameter, the fresh weight and dry weight of roots and plants, instrumental color, pH, titratable acidity, total soluble solids, the ratio of soluble solids to titratable acidity and moisture content. It was concluded that the type of production system does affect attributes of lettuce quality with distinctions between cultivars. The most intense distinctions were found under the hydroponic system. |
