Results: Seeds per pod reduced when flowers are abundant.
Slide 17 of 31
(Figure: Bar Graph). There were significantly more seeds per pod for
low standing crop treatments (in red) than for high standing crop treatments
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.
