Effect of regulated deficit irrigation on commercial quality parameters, carotenoids, phenolics and sugars of the black cherry tomato (Solanum lycopersicum L.) ?Sunchocola?

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