EXST7015 Daily Design 11 Carefully read the description of the experiment below. Be prepared to answer the questions that follow the design description as a class quiz. Endophytes are organisms that live within another organism without causing apparent harm. The endophytes in this study are fungi living in an invasive aquatic plant called Eurasian water milfoil. A greenhouse study was conducted to test effects of stress induced by simulated chemical runoff on endophyte- infected and endophyte-free Eurasian water milfoil. Simulated chemical runoff stress was induced by applying low rates of the herbicide endothall for a 24-hour exposure time. Applications included no endothall (0 mg/L), 0.5 mg/L and 1.0 mg/L applied to both endophyte-infected and endophyte-free Eurasian water milfoil plants. Eighteen 55 L aquaria were filled with a water based culture solution recommended for aquatic plant growth. Lake sediment collected from
