Fruit development of Tartary buckwheat under exogenous paclobutrazol treatment. (A) GA content during fruit development. (B) Final weight of fruits treated with different concentrations of exogenous paclobutrazol. x-axis: weight of mature fruit, y-axis: concentration of paclobutrazol treatment. (C) Images of fruits treated with exogenous paclobutrazol during fruit development. (D) Differences in the expression of DELLA subfamily genes under exogenous paclobutrazol treatment during fruit development. Mock: the same amount of water treatment, paclobutrazol: 160 mg·L^− 1 paclobutrazol treatment. Error bars were obtained from fifteen measurements. Small letter(s) above the bars indicate significant differences (α = 0.05, LSD) among the treatments. * indicate significant correlations at the 0.05 and 0.01 levels, respectively
