Coefficients of correlation of amplitudes of LERs, induced by different temperature transitions, with the relative residual photosynthetic assimilation of CO₂ (${\text{A}}_{\text{CO}2}^{\text{a}.\text{h}.,\text{rel}}$), effective (${\Phi }_{\text{PSII}}^{\text{a}.\text{h}.,\text{rel}}$) and maximal (F_v/${\text{F}}_{\text{m}}^{\text{a}.\text{h}.,\text{rel}}$) quantum yields of photosystem II after heating. The group with LER observed during the 1st transition included 18 peas (n = 18), the group with LER observed during the 2nd transition included 32 peas (n = 32), and the group with LER observed during the 3rd transition included 23 peas (n = 23). Individual amplitudes of LERs for the each temperature transition in the each plant were used. ^*The correlation coefficient is significant.
