Abstract:
By microscopic measurement and in vitro germination，pollen morphology and germination characteristics of three triploid germplasms of peaches were observed and analysed，to contrast that of the same origin of diploid of peaches.The results showed that，for triploid，the size and shape of pollen varied between a large scale，no regular mode of the distribution of pollen grain sizes could be drawn，pollen minor diameter mode proportion of triploid ranges in 20.0%-40.0%,far lower than that of diploid，which was 66%-76%;the pollen germination rate of triploid was low，only 4.08%-17.52%，while that of diploid was up to 60.8%-75.8%.Thirdly，most of germinated pollens of diploid peaches were the ones with (67.1±7.1)×10.3 μm3 as their volume，While those of triploid ‘10-15-23’,‘10-15-16’ were larger pollens in volume （95.3±7.1)×10.3 μm3.
