In this and the next three graphs, the x axis is the number of flowers in
bloom on a raceme, and the y axis is the percent of all racemes that have x
number of flowers in bloom. Iíve plotted the distributions for the
commercial fields that we monitored (see the previous slide
show for methods, and total
flower abundance). Each
symbol represents a different field. The solid
line is the average. For example, on average only 4% of the racemes have a
single flower in bloom in the figure above.
Early in the season before the bees have done much pollinating there is great
variability in flowers per raceme, with low percentages of racemes having
everything from one flower to 25. Actually Iíve truncated the distribution;
there are some racemes with up to 40 flowers. These are the distributions the
first week that bees were released into the field. The distribution is flat
because flowers are accumulating without being pollinated. As pollination
