Fig. 1: The effects of gibberellins on ‘Dangshansuli’ pear fruit set.

Fruit set rate in response to unpollination, pollination and different concentrations (from 25, 50 and 75 mg L−1) of GA3 and GA4+7 (from 25, 50 and 75 mg L−1) at 20 DAA. Values of fruit set were means of three replicates with 30 ovaries per replicate (±SD). Significant differences (P < 0.05) between treatments are showed by different letters according to Duncan’s test
