I am analyzing an experiment where I grew two genotypes (native and invasive) of the same plant in one pot and evaluated growth over time. Half of the pots had two plants of the same genotype (native-native) and the other half with one of each genotype (native-invasive). These pots were then either placed in a herbivory or no herbivory treatment. Each plant was then harvested, dried, and weighed separately. I would like to compare the growth of each plant in the two genotype (competition) treatments to each other and evaluate if herbivory affected these growth patterns. Since two plants were grown in one pot, do I need to somehow nest plants in pot?
Research question: does herbivory differentially affect native genotypes grown with other natives versus native plants grown with invasive genotypes?
