(Figure: Bar Graph).  There were significantly more seeds per pod for low standing crop treatments (in red) than for high standing crop treatments (in blue).
My hope was to find a significant interaction term in this analysis, indicating that this difference between high and low standing crop is greater for the minimum movement treatment than for other movement patterns. This would occur because there are more flowers available per plant when standing crop is high, so more movement can take place within a plant. The data show a trend in this direction (note lower blue bar for the minimum cross pollination than for other movement patterns). However, the interaction term was not significant. Because of high variability between plants, I estimated that it would have taken many more replications of the experiment to prove that the interaction term was significant.
But at least the effect of standing crop was clear.
