RESEARCH ON FRUITS QUALITY OF DIFFERENT TOMATO (Lycopersicon esculentum Mill.) CULTIVARS IN VIDRA AREA, ILFOV COUNTY.

Under field conditions, during 2016, were studied 15 cultivars of tomatoes. When the fruit reached commercial maturity, the following quality indices were determined: water content and total dry substance (gravimetric method), soluble dry substance (refractometric method), titratable acidity (titrimetric method), total carbohydrates (Fehling Soxhlet method) and vitamin C (iodometric method). The best results on the quality of tomato fruits were obtained with the following cultivars: St. Pierre (7.33% total dry substance, 4.2% soluble dry substance, 0.67% acidity, 3.50% carbohydrate and 19.36 mg vitamin C), Caspar F1 (5.98% total dry substance, 3.8% soluble dry substance, 0.60% acidity, 3.20% carbohydrate and 21.12 mg vitamin C), Mirsini F1 (5.68% total dry substance, 4.0% soluble dry substance, 0.64% acidity, 3.30% carbohydrate and 21.12 mg vitamin C), Heintz (5.67% total dry substance, 3.7% soluble dry substance, 0.80% acidity, 3.10% carbohydrate and 24.64 mg vitamin C) and Darsirius (5.21% total dry substance, 3.9% soluble dry substance, 0.69% acidity, 3.20% carbohydrate and 19.36 mg vitamin C).
