The results showed that: different concentrations of sucrose and boric acid had significant impact on pollen germination, but different concentrations of calcium had no significant impact on pollen germination. It was most appropriate for tube elongation when sugar 150 gL^(-1) and boric acid 100 gL^(-1). Lack of sucrose would lead to the accumulation of callose in top of pollen tube and hold back its growth. The distribution of callose was regular in pollen tube when the medium lacked boric.
