摘要: This study was conducted with the objective of testing hypothesis that tomato fruits from organic farming accumulate more nutritional compounds, such as phenolics and vitamin C a consequence stressing conditions associated system. Growth reduced in while titratable acidity, soluble solids content concentrations were respectively +29%, +57% +55% higher at stage commercial maturity. At time, total phenolic +139% than conventional which seems consistent two times activity phenylalanine ammonia lyase (PAL) we observed throughout fruit development farming. Cell membrane lipid peroxidation (LPO) degree 60% tomatoes. SOD also dramatically Taken together, our observations suggest experienced resulted oxidative stress accumulation sugars other compounds contributing to quality compounds.
