Foliar boron spray increases the fruit-setting rate in YD and SX Longan cultivars. The Y-axis of the chart represents the fruit setting rate in percentage, the columns show mean ± standard deviation of the biological replicates (n = 3) of both SX and YD, with and without boron spray, and the asterisks indicate significant differences between boron unsprayed and sprayed plant at a significance of p ≤ 0.05 (*) in student’s t-test
