As shown in figures 5 and 6 the vitamin C andlycopene content of tomato fruits are bigger fortreated variants than control regardless ofvariety.Figure 8. Soluble carbohydrates and acidity contenthybrid Balkan F1CONCLUSIONSFigure 5. Vitamin C and lycopene content in varietyGhittiaFigure 6. Vitamin C and lycopene content in hybridBalkan F1Regarding the carbohydrates content it can beobserved that it does not vary much bytreatment. The acidity of tomato fruits variesquite widely depending on the treatment andvariety (Figure 7 and 8).Growth promoter and foliar fertilizer treatmentshad a positive influence on the level ofproduction and quality of tomato fruits grownin high tunnel, Poiana county Ialomita 2012.Highest yield was obtained at Agriphytetreatment for both varieties Ghittia and BalkanF 1 (66.957 t/ha, respectively 69.626 t/ha).Regarding the distribution of fruits on thequality classes, Ghittia shows in variant treatedwith Agriphyte, the biggest share ofextra fruit quality class (40% of totalproduction).Production results were interpreted statistically.The differences between Balkan F 1 and Ghittiais distinctly significant and between control andtreated variants were very significant.Vitamin C and lycopene contents variedpositively according to the treatment.The highest content of vitamin C was recordedin variety Ghittia treated with growth promoterP& R (21.52%) and the highest lycopenecontent was at Balkan F 1 hybrid treated withAgriphyte (69.39 ppm).ACKNOWLEDGEMENTSFigure 7.
