Characterisation of combined abiotic and biotic stresses effects on lettuce plants <i>via</i> a multi-analysis approach.

On the other hand, if the K content in control plants was about 3.5 g/kg ( Figure 8 ), featuring a C/K ratio of roughly 3, in stressed plants it was higher than 8 g/kg, leading to a net rise of 2.5 g/kg (p< 0.01) and an interaction effect between biotic and nutritional stress nearing significance (p = 0.08). 3.2.6.2 Mesonutrients The level of Ca in control plants was approximately 400 mg/kg based on FW, as reported in Table 1 .
