Proceeding of the 4 rd International Symposium“NEW RESEARCH IN BIOTECHNOLOGY” USAMV Bucharest, Romania, 2011at harvest period are lower than maximum quantities allowed by standards for freshtomatoes fruits (300 ppm), the lower value being found for Lady Rosa F1.Regarding phosphates and potassium it can be observed that the quantities aregrowing during development and have high values at harvest which means a very goodquality of tomatoes especially in the case of Lady Rosa F1.The results of biochemical parameters of tomatoes fruits are presented in Table 2.220Nocrt.Table 2. Biochemical results of tomatoes fruitsC Vitamin, SolubleVariety TA, %mg/100g glucides, %Lycopene,mg/kg1 Amanda 0,510 12,625 4,798 19,118 4,6503 Lady Rosa 0,578 15,100 4,550 23,350 4,3752 Menhir 0,428 16,100 4,780 15,995 4,275The tritable acidity varies from 0,428 % at Menhir F1 cultivar to 0,578% at LadyRosa F1. The ascorbic acid levels in fresh fruits analyzed reveal that Menhir F1 has thehighest value of 16,1 mg/100g fresh fruit and the low level it was found at Amanda F1 with12,625 mg/100g fresh fruit.Regarding the soluble glucides the most tasty cultivar is Amanda F1 with 4,798%concentration of soluble glucides and also this variety has the high pH of 4,65 comparewith Lady Rosa F1 and Menhir F1 which have 4,375 respectively 4,275.Regarding lycopene quantities the highest value was found at Lady Rosa F1cultivar, this variety having the most intense red color compare with the other two cultivars.4. CONCLUSIONSIn the case of agrochemical parameters analyzed it can be say that the nitratesquantities have decreased at all varieties tested and the lower value it was found at LadyRosa F1 with 198,3 ppm.Regarding phosphates and potassium accumulation, these two parameters beingresponsible for a good resistance at transport and shelf life of the fruits, all varietiesaccumulated, during vegetative development high quantities and the best results was foundat Lady Rosa F1 cultivar.From the point of view of biological factors analyzed all of varieties testedrevealed good results. The high concentration in ascorbic acid was found at Menhir F1 andthe highest concentration of glucides was found at Amanda F1 cultivar. Regarding totalacidity and lycopene concentration the Lady Rosa F1 had the best results.In conclusion all cultivars testes have the quality standards for human consumptionand the best results were found at LADY ROSA F1 cultivar.REFERENCES1.
