Impact of Water Deficit on Nutritional Quality of Tomatoes

Pevicharova Galina; Ganeva Daniela; Grozeva Stanislava

The answer of promising tomato genotypes to the water stress on some basic chemical compounds related to the biological value and sensory quality of the fruits was evaluated. Ten Bulgarian tomato genotypes were on the focus. They had been determined as tolerant to drought in a large Bulgarian collection after two-year experiment. The applied reduced irrigation led to an improvement of the nutritional quality of the tomato fruits. All studied genotypes reacted with an increase of the total soluble solids and ascorbic acid contents in reduced irrigation. A genotype reaction toward water deficit was better expressed in contents of lycopene and titratable organic acids.
