Changes in Polyphenols Contents and Antioxidant Capacities of Organically and Conventionally Cultivated Tomato (Solanum lycopersicum L.) Fruits during Ripening

Figure 3

Results of Wilcoxon tests comparing orange tomatoes with green (horizontal axis) and red (vertical axis) tomatoes. The values are presented in log₁₀-scale (dotted lines at ±3 correspond to ) multiplied by the sign of difference: in right lower corner are compounds with the highest values in green tomatoes, in left upper corner are compounds with the highest values in red tomatoes, and in left lower corner are compounds with the highest values in orange tomatoes (right upper corner corresponds to nonexisting compounds with higher values in both green and red tomatoes). Filled circles denote compounds different in green and red tomatoes (). Points’ labels present compounds’ m/z values and are explained in Table 1.
