Abstract:
With 60 individual 4-year-old trees of the blueberry cultivar‘Sharpblue’as materials，the effects of rainfall on pollen viability and stigma receptivity were studied，to provide scientific basis for cultivation，flowering management of blueberry.The results showed that the continuous wet weather had a greater negative impact on pollen viability，the pollen viability was extremely low or no vitality whiles the rainy lasted more than 3 days.Simultaneously，the stigma was extremely low or no receptivity whiles the corolla and the stigma with water drop or film.And the aforementioned results showed that the pollination efficiency was reduced by continuous rainy weather，which had great negative effect on the production of blueberry.
