Connection of the relative 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 with parameters of LERs. (A) The relative residual effective and maximal quantum yields of photosystem II after heating in peas with different quantities of LERs during the stepped heating. The group with three LERs included 10 peas (n = 10), the group with two LERs included 16 peas (n = 16), and the group with one or no LERs included 14 peas (n = 14). ^*p < 0.05 compared with parameters in the group with one or no LERs, Student t-test. (B) The relative residual effective and maximal quantum yields of photosystem II after heating in peas with a different number of temperature transition, which induced the first generation of LER during the stepped heating. The group with the first LER induced by the 1st transition included 18 peas (n = 18), the group with the first LER induced by the 2nd transition included 16 peas (n = 16), and the group with the first LER induced by the 3rd transition or without LERs included 5 peas (n = 5). ^*p < 0.05 compared with parameters in the group with the first LER induced by the 3rd transition or without LERs, Student t-test.
