Fig. 1: Fruit retention and size from treatment to harvest.

a Average percentage of remaining fruit on each treated tree every 2 weeks, from initial treatment to 50 days after treatment (DAT), and at harvest once mature (132 DAT). Error bars indicate standard error among three replicates. Shaded regions indicate periods of fruit drop. At maturity, statistically less GA₃-treated fruits were retained than HP or OP, but more than any other treatment. Statistical comparisons are reported in Table S1. b Average size of fruit present on each treated tree every 2 weeks, from 2 weeks until 50 DAT and at harvest once mature. Initial measurement (0 DAT) is estimated. At maturity, GA₃-treated fruits were statistically similar in size to HP and OP. NAA and GA₃ + NAA-treated trees had no fruit at time of harvest. NPA-treated and negative control (NC) trees had three and six fruits, respectively, all except one NC fruit had seeds. As these were likely missed in staging, size data were omitted past 14 DAT. Statistical comparisons are reported in Table S2. HP hand pollinated, OP open pollinated
