Abstract

In this preliminary study, the effect of regulated deficit irrigation (RDI) on the commercial quality (size, weight, soluble solids, firmness and colour), content of carotenoids, phenolics and sugars of black tomato (Solanum lycopersicum L.) ʽSunchocolaʼ was studied. Two water irrigation treatments were applied: regulated deficit irrigation (RDI) and control with 82,7 and 398 mm of water supplied, respectively. Tomato of the first cluster harvested at three stages of maturity were studied. The size and weight of the tomato did not present significant differences regarding the RDI and maturity. In both groups the concentration of carotenoids and phenolics increased with the degree of maturity (on average 57 % and 8 % respectively). On the other hand, in most cases, the content of carotenoids, phenolics and sugars showed significant differences between irrigation treatments (p < 0.1). In conclusion, with the application of the RDI, it was possible to maintain the size and weight and increase the carotenoid levels of the fruits.
