This summer, my research partner and I were tasked with collecting pH data from the Sticky Monkey flower plots in the Stanford dish. This process included identifying the flower age by looking at the anther status an organ that helps us determine the flowers age. We also looked at the stigma status which indicates whether or not a flower was recently visited by a pollinator. We collected pH data from over 400 flowers which revealed that 1. Flowers with a closed stigma are more likely to have a lower nectar pH and 2. Nectar pH decreases as a flower’s anther status increase. Check out my video to understand why these findings are significant.
