Figure 4

Effect of cold acclimation on superficial scald incidence. (a) Schematic representation of the experimental design. Early harvested fruit were cold acclimated at 8 °C for 1 week (H1-acclim, light blue) and compared to fruit not acclimated (H1) or harvested 1 week later (H2). Fruit were stored in classic cold conditions (blue arrow) and phenotyped for scald incidence after one week of shelf-life at room temperature (orange arrow). (b) Incidence of superficial scald injuries after 4 months cold storage according to acclimation treatment and harvest stage on fruit collected from two different orchards (R06 and R11). Values are binomial proportions and confidence intervals for n = 100 and α = 0.05. (c) Effect of acclimation on relative gene expression in fruit peel samples after one day (1D) and one week (1W). Expression relatively to classic cold storage for HSP17.6CII (MD15G1053800), HSP21 (MD13G1108500), HSP90.1 (MD01G1208700), HSP101 (MD06G1201600), PAL (MD12G1116700), PR5 (MD04G1064200), FAR (MD10G1311000) and PPO (MD10G1299400). Data are mean values ± SD of n = 3 for fruit collected in both orchards R06 and R11.
