LB—lettuce ‘Bionda da taglio’; CI—chicory ‘Italico a costa rossa’; CM—chicory ‘Molfetta’. Within the same main effect and for each parameter, the same lowercase letters in the same column indicate that the mean values are not significantly different (p = 0.05). A G × K significant interaction is reported in Figure 4. Significance: *** and * are for p ≤ 0.001 and p ≤ 0.05, respectively; NS—not significant.
