There was a significant difference between LEF, PQ SPAD, and ΦII in Acer rubrum trees and Hydrangeas.
Interpretations of results show a significant difference in mean LEF, with Hydrangea bushes containing higher values than Acer rubrum trees (Fcrit<Fstat). There was also a small, yet significant difference in the mean PQ SPAD values (Fcrit<Fstat).
Results show that there is some significant difference in ΦII values between Acer rubrum *03, Acer *06, and all three Hydrangea bushes (Fcrit<Fstat). There was a significant decrease of ΦII in the Acer rubrum *07 which is mostly the result of this tree being taller and thinner than *03 and *06.
The results display all three Hydrangea bushes vs. Acer rubrum trees. The data collected shows there is little significant correlation between mean PQ SPAD and mean ΦII against the plant height in meters. There is a significant negative correlation between LEF and plant height; as plant height increases, LEF decreases.
The difference between the LEF, PQ SPAD, and ΦII in Acer rubrum trees and Hydrangea bushes shows a significant relationship between height and photosynthetic characteristics.
It was concluded that Hydrangea bushes have higher capability of doing photosynthesis because their linear electron flow was greater than the Acer rubrum trees meaning it is easier for the Hydrangea bushes to make energy.
The results showed the opposite of the original hypothesis with the Hydrangea bushes being shorter and having better photosynthetic characteristics than the Acer rubrum trees.
Future experiments will include looking at organisms that are closer to the height of the Hydrangea bushes. Experiments will conclude if the amount of LEF in the same in all plants the same height or if the bushes are better at converting energy than different bushes.
