dc.description.abstract Parasitic plants have been identified as potential biological agents to control invasive plants. Understanding the interaction between invasive plants and their novel natural enemies is important for understanding mechanisms underlying plant invasion success and thus taking measures to control invasion. We conducted a factorial experiment to test the interactive effects of nutrient addition (low vs. high) and parasitism (with vs. without Cuscuta australis) on the growth of the invasive Bidens pilosa. Parasitism significantly decreased leaf, stem and root biomass of the host invasive plant, and nutrient addition increased leaf and stem biomass of the host. A synergistic effect of parasitism and nutrient addition was found on stem and leaf biomass of the hosts. Nutrient addition significantly increased vegetative biomass of the parasitic plant and caused a more deleterious effect on the invasive host. Reproductive biomass of the parasitic plant was significantly positively related with net photosynthetic rate, light-utilisation efficiency and apparent carboxylation efficiency. Vegetative biomass and total biomass of the parasitic plants were significantly positively related with specific leaf area and the relative chlorophyll content of the host plant. The deleterious effect of the parasite on the growth of the host plant was significantly positively correlated with vegetative biomass of the parasitic plant. Nutrient addition increased the negative effect of the parasitic plant on the invasive host, indicating that the parasitic plant is potentially a biological control agent for the invasive plant even in the context of changing global resources. en_US
