Abstract

Numerous studies show that an appropriate diet rich in bioactive compounds such as carotenoids and phenolic compounds, among others, can reduce the risk of developing diseases. In this context, the consumption of functional foods continues to gain importance. In addition to providing nutrients, functional foods provide other compounds that have a beneficial effect on certain functions, reducing the risk of suffering from diseases or improving the state of health. On the other hand, water is a scarce commodity and the volume available for agricultural use is very limited in some regions. Therefore, the efficient use of this resource should be a criterion to be considered in the implantation of new crops and the use of those already implanted. Currently, products grown under water-saving conditions are called hydrosustainable products. Some studies indicate that the use of controlled deficit irrigation techniques can contribute to increase certain bioactive compounds, improve some sensory attributes, not affect the productivity of the crop and, finally, are respectful with the environment due to the optimization of water use. In the present doctoral thesis the commercial and functional quality were evaluated based on the content of carotenoids and phenolic compounds of tomato (Solanum licopersicum L.) in function of different agronomic factors, and the content of functional compounds (carotenoids and phenolic compounds) in flowers with a view to enhancing their interest in food. With respect to the study of tomato the commercial quality, the content of carotenoids and phenolic compounds in different varietal groups were evaluated in: 1) eleven varieties of tomato with diverse colorations: five commercial cherry varieties available in supermarkets in Seville (ʽCherry amarilloʼ, ʽCherry peraʼ, ʽCherry naranjaʼ, ʽMinichocmatoʼ and ʽCherry rojoʼ) and six varieties grown in greenhouses under normal irrigation conditions (ʽGreen Zebraʼ, ʽSuncholaʼ, ʽTigerellaʼ, ʽByelsaʼ, ʽPalamósʼ and ʽOrangeʼ); 2) two cherry varieties (ʽLazarinoʼ and ʽSummerbrixʼ) and three commercial varieties (ʽByelsaʼ, ʽPalamósʼ and ʽTigerellaʼ) subject to controlled deficit irrigation (90% water reduction with a leaf water potential not exceeding -1.2 MPa) and the position of the bouquet was also evaluated; 3) two cherry varieties (ʽLazarinoʼ and ʽSummerbrixʼ) subjected to controlled deficit irrigation (water decrease by 78 % in the autumn crop with a leaf potential that did not exceed -0.8 MPa and 80 % in the spring with a leaf potential that did not exceed -1.0 MPa) during flowering, fruit set and fruit maturity, the development level of the bouquet, the degree of maturity and the crop cycle were also evaluated; 4) the position of the fruit in the bouquet in two cherry varieties (ʽLazarinoʼ and ʽSummerbrixʼ).
