Connection of the relative residual photosynthetic assimilation of CO₂ after heating with parameters of LERs. (A) The residual CO₂ assimilation after heating in peas with different quantities of LERs during 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 residual CO₂ assimilation after heating in peas with different numbers 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. (C) Scatter plots between the average amplitude of LER during stepped heating and the relative residual photosynthetic assimilation of CO₂ after heating (n = 40). The average amplitude of LER was calculated for the each plant. It has been assumed that the average amplitude equaled zero when LERs were absent in the plant. R is Pearson's correlation coefficient.
