Abstract:
In this study，using the ‘Britewell’ as test materials，the pollen germination and pollen tube growth of self-pollination and cross-pollination after detasseled 0，1，2，3，4，5 days and 6 days were investigated，and the flowers pollinated were sampled 2，6，12，24，48，72 and 96 hours after pollination.So as to elucidate effects of flower age on pollen germination，pollen tube growth and fruit set of Rabbitteye blueberry，to provide knowledge for artificial supplementary pollination and crossbreeding.The results showed that there was a significant difference in pollen germination and pollen tube growth and fruit set among different growth-phase flowers of self-pollination or cross-pollination.In 1-4 days after flowering,the rate of style traversed by pollen tubes of flowers was significantly higher than other growth-phase flowers.Meanwhile，the self-incompatibility was observed in ‘Britewell’，and the base of style was the key position of self-incompatibility，and the self-incompatibility was reduced to a certain extent by bud pollination and delayed pollination.In short，it was the 1-4 days after flowering that the best time of artificial supplementary pollination and crossbreeding.
