为了优化南方高丛蓝莓低寒杂交品种的果实产量（尤其是早熟、坐果和果实重），研究了蜜蜂访访水平和花粉来源的变化。结果植物（' Gulfcoast '）与蜜蜂（Apis mellifera L.）和授粉植物一起被围在尼龙网箱中，这些授粉植物要么在叶面内自花授粉，要么进行品种间杂交，要么与蓝莓（Vaccinium ashei Reade）进行种间杂交。新开放的花朵被允许0、1、5、10或无限蜜蜂访问，然后用细网袋关闭。在一次和五次访问之间，以及通常在五次和无限次访问之间，果实性状取得了显着改善。在访问次数最少和最多的水平之间，水果的数量增加了两倍以上；Set的峰值接近70%。授粉到收获的时间间隔是早期蓝莓价格的主要决定因素，缩短了5 d，达到53±0.5 (SE) d。莓重比0和1次访问组增加了28%，达到每粒1.77±0.05 g。种子数量增加2.2倍，达到每个浆果40±1粒种子。果汁的糖浓度在11.0%到12.9%之间，蜜蜂到访程度越高，果汁的糖浓度越低。花粉源对‘Gulfcoast’果实性状均无显著影响。
Bee visitation levels and pollen sources were varied in an effort to optimize fruit production (especially early ripening, fruit set, and berry weight) of southern highbush blueberry (low chill hybrids of Vaccinium corymbosum L.). Fruiting plants (‘Gulfcoast’) were enclosed in nylon-mesh cages with colonies of honey bees, Apis mellifera L., and pollinizer plants affording either intravarietal self-pollination, intervarietal crossing, or interspecific crossing with rabbiteye blueberries, Vaccinium ashei Reade. Newly opened blossoms were allowed 0, 1, 5, 10, or unlimited bee visits before being closed with a fine mesh bag. Significant improvements in fruiting characters were achieved between one and five visits and also usually between five and unlimited visits. Fruit set more than tripled between the fewest- and greatest-visit levels; set peaked near 70%. The pollination-toharvest interval, a chief determinant of blueberry prices in the early season, was shortened by 5 d to 53 ± 0.5 (SE) d. Berry weight increased 28% from the 0- and I-visit groups to 1.77 ± 0.05 g per berry with unlimited visits. Seed numbers increased 2.2-fold to 40 ± 1 seeds per berry. Sugar concentration of juice ranged from 11.0 to 12.9% and was lower at greater levels of bee visitation. Pollen source did not have a significant effect on any fruiting character measured in ‘Gulfcoast’.
