Sample C1

Calyx tubes at 6 days after 6000 × Flusilazole + 300 × PBO treatment

Sample C2

Calyx tubes at 6 days after 50 mg/L GA₃ treatment

Sample C3

Yellow loop in abscission zone from calyx tube at 10 days after 6000 × Flusilazole + 300 × PBO treatment

Sample C4

Calyx tubes at 10 days after treated with 50 mg/L GA₃

Sample C5

Abscission zone from calyx tubes at 22 days after 6000 × Flusilazole + 300 × PBO treatment with calyx removing

Sample C6

Calyx tubes were still present at 22 days after 6000 × Flusilazole + 300 × PBO treatment

Sample C7

Calyx tubes were still present with control at the same time as in C6
