BRs suppress pear fruit ripening. Endogenous BR content during pear fruit development was measured in 2020 (A). Fruit collected on the day of commercial harvest (135 DAFB) were treated with EBR or Brz, an inhibitor of BR biosynthesis, and stored at room temperature for 15 d (B). After treatment, ethylene production (C), fruit firmness (D), and endogenous BRs (E) were measured. RT-qPCR was used to examine the PuBZR1 expression level in EBR- and Brz-treated fruit (F) as well as in fruit during development (G). The expression level of PuACO1 (H), PuACS1a (I), and PuERF2 (J) was also investigated. Untreated, fruit not receiving any treatment; EBR, fruit treated with EBR; Brz, fruit treated with Brz. Bars, 1 cm. The x-axes indicate the number of days of storage at room temperature after harvest; 0 indicates the fruit harvested on the day of commercial harvest. Three biological replicates were analyzed as described in the Materials and Methods section. Values represent means ± SE. Statistical significance was determined using a Student’s t test (**P < 0.01).
