Results from PI 2017

Thank you to all those that participated in the 2017 Pollination Investigators program!  The results detailed below are from experiments conducted all across Ohio.  If you are interested in the data from your garden, please send an email to pollinationinvestigator@gmail.com to let us know.

 

Figure 1.  The number of peppers per plant did not vary among exclusion, open, or hand pollinated treatments.  Thus pollinator activity did not influence the number of peppers produced in the garden habitats sampled.

Figure 2.  The weight of peppers per plant did not vary among exclusion, open, or hand pollinated treatments.  Thus pollinator activity did not influence the weight of peppers produced in the garden habitats sampled.  However, the exclusion cage treatment was slightly reduced from the open treatment.

 Figure 3.  The number of seeds per pepper plant did vary among exclusion, open, and hand pollinated treatments.  Peppers from the exclusion treatment (no pollinators) had fewer seeds than peppers from the open or hand pollinated treatments!

So what’s next for these data?  We would like to see how the local environment surrounding each of the gardens influenced these results, specifically the effect on seed production.  We will obtain landscape maps and analyze percentage cover of forest, urban, grassland, cropland, etc around each garden at a spatial radius of 1000 meters, relating this to the relative difference in seed count between the open and exclusion treatments.
