Now, in the Lactuca serriola growth and leaf re-orientation experiments, not all plants were of equal size at the end of the experiment. This may indicate that there were some genetic differences in the plants we randomly chose for these experiments. However, when we measured the relationships between reproductive output (number of flowers produced) and plant size, there were quite interesting results (see below). The "natural orientation" is our control group and the "horizontal orientation" is our experimental group. the two regression slopes are significantly different from each other.
