高丛蓝莓的平均大小与平均种子数直接相关。这两个变量直接相关的授粉水平和收获时间。种子数量的差异只占一个锅的浆果大小的总变异时，个别浆果进行评估。在早期的季节收获和高授粉水平的条件下，种子数量占所观察到的大小变化低至10%。相比之下，在本赛季后期或低授粉水平的条件下，这一因素占高达59%的浆果大小观察到的变化。可能浆果的大小增加相当多时，浆果有一个高的补充种子相比，那些有几个，但种子最小后，本进一步增加的大小是不成比例的种子数量增加。平均而言，约50%的浆果大小观察到的变化必须解释的因素以外的种子数量。
Average size of highbush blueberries was found to be related directly to average seed number. Both variables were related directly to pollinator level and time of harvest. Differences in seed number accounted for only a pan of the total variability in berry size when individual berries were evaluated. During the early-season harvest and under conditions of high pollinator levels, seed number accounted for as low as 10% of the observed size variation. By contrast, late in the season or under conditions of low pollinator levels, this factor accounted for as much as 59% of the observed variation in berry size. Probably berry size increased considerably when berries had a high complement of seeds compared with those that had few but after a seed minimum was present further size increased was not proportional to increased seed number. On the average, about 50% of the observed variation in berry size must be explained by factors other than seed number.
