Apocynum cannabinum, also known as hemp dogbane, is a species of perennial native to the U.S. This species has been found to be extremely plastic, meaning that its environment has significant effects on its phenotypic traits (Ransom et al. 1998). Plant-herbivore interactions, such as herbivory, can drive this plasticity. One of these responses includes the induction of Latex, a white sappy fluid that exits leaves and stems induced by damage (Agrawal and Konno 2009). This project investigates the effects of early-season vs. late-season herbivory on hemp dogbane, as well as how latex induction is influenced by these plant-herbivore interactions.
