Media used for the Sucrose concentration test

Treatment	pH	Sucrose (g/L)	PEG4000 (g/L)	Boric acid (mg/L)	Calcium nitrate (mg/L)	Germination rate (%)
Sucrose medium 1	6.0	0	100	100	200	3.9 ± 2.0
Sucrose medium 2	6.0	50	100	100	200	64.8 ± 4.3*
Sucrose medium 3	6.0	100	100	100	200	31.9 ± 2.2
Sucrose medium 4	6.0	150	100	100	200	23.1 ± 3.0
Sucrose medium 5	6.0	200	100	100	200	6.0 ± 1.7
Sucrose medium 6	6.0	250	100	100	200	3.4 ± 1.2
Sucrose medium 7	6.0	300	100	100	200	0.7 ± 1.0

Germination rate is the mean ± SD of five replicates. * Indicates the first echelon of multiple comparison results. The ANOVA results indicated that pollen germination rates differed significantly (P < 0.001) between the different Sucrose concentration treatments
