tactics have been employed in the past to enhance bee pollination in crops including blueberry, where environmental conditions are often suboptimal during bloom or the crop is not attractive to bees ( Sagili et al., 2015 ). Most of the blueberry plantings

treatments and five fruit were harvested among all the female plants from crosses using the 300-Gy dose. The rate of fruit abscission 45 d after pollination was lower for the 50- and 150-Gy doses than for the 300- and 600-Gy treatments. There was no
