The response of rice plants to cold stress. a and b, The photograph of ZZ39 and RIL82 plants under control and cold stress conditions, respectively; c, Chlorophyll content; d, REC; e, Fv/Fm; f, Y (II). Chl, Chlrophyll; REC, Relative electrical conductance; Fv/Fm, Maximum fluorescence quantum of PSII; Y (II), Actual fluorescence quantum of PSII. Vertical bars denote standard deviations (n = 4). A t-test was adopted to compare the difference between control and cold stress within a cultivar. * denotes P < 0.05
