Parameters Symptomatic for Boron Toxicity in Leaves of Tomato Plants

Figure 4

Analysis of the lineal regression where biomass (x axis, left) and the foliar concentration in B (x axis, right) are compared with the concentration of O₂₋, H₂O₂, and MDA (y axis) in the leaves of two tomato cultivars (Kosaco and Josefina). The significance levels are represented by *(𝑃<0.05), **(𝑃<0.01), ***(𝑃<0.001) and ns (non-significant; 𝑃>0.05).
