In addition, the fruit set, berry weight and seed counts of clusters that were bagged to exclude pollinators (and thereby measure parthenocarpic set fruit) were not statistically different between field sizes or positions, indicating little variation in the underlying ability of flowers to set fruit. The proportion of open-pollinated flowers that were set to become berries was slightly higher http://www.selleckchem.com/screening/pfizer-licensed-library.html in large fields (0��92?��?0��02%) than in small fields (0��89?��?0��02%), but this difference was not statistically significant (F1,20?=?1��14, P?=?0��29), and there was no significant variation in fruit set between sampling positions (Table?2). Fruit on open-pollinated clusters weighed 50% more in large fields compared with small fields (F1,20?=?18��27, P?=?0��0004) (Table?2) and there was no difference between sampling positions (F1,20?=?0��3, P?=?0��87). This increase in fruit size was associated with an increase in the number of seeds per berry, with higher seed counts in berries from large fields compared with those from small fields, but no variation between the field positions (field size F1,20?=?14��6, P?=?0��0011; field position F1,20?=?0��31, P?=?0��58) (Table?2). Calculation of the difference in fruit parameters between the bagged and open clusters on each bush provides a measure of the benefit provided by pollination, taking into account the underlying parthenocarpic productivity potential of each blueberry bush (Eck 1988). There was little change in fruit set between pollinator-excluded and open-pollinated clusters (3��24% increase in large fields and 5��2% increase in small fields), with no difference in fruit set between field sizes (F1,20?=?0��14, P?=?0��72) or field position (F1,20?=?0��00, P?=?0��98). Exposure to pollinators had a much larger effect on berry weight: berries in large fields were 0��38?g heavier on average in large fields when exposed to pollinators, but only 0��14?g heavier in small fields when exposed (F1,20?=?12��28, P?=?0��002), and with no difference between field positions (F1,20?=?0��13, P?=?0��72). There was also a much higher number of mature seeds per berry in open-pollinated fruit from large fields (22��6?��?2��7) than from small fields (13��5?��?3��1) (F1,20?=?14��47, P?=?0��0011), with no significant variation between the sampling positions (F1,20?=?0��39, P?=?0��54) (Table?2). Pollinator-excluded clusters contained berries with
