Abstract:: Taking Prunus armeniaca L.cv ‘Katy’ as material，the pollen germination rate and the pollen tube length that different types of mediums and different concentrations of sucrose and boric acid were determinated.The effect of different types of mediums and different concentrations of sucrose and boric acid for pollen germination and pollen tube elongation were studied.The results showed that,most suitable medium for Prunus armeniaca L.cv ‘Katy’ was 10% sucrose+0.10% boric acid+0.5% agar.It was more than 90% pollen germination rate and the length of pollen tube growth 13 510.30 μm in vitro.
