When: Thursday, October 26, 2017, 12:30-1:15pm in ASAC 319
Speaker: Dr. Jason Welch, faculty at St. Louis University
Description: This seminar will discuss the ozone garden in the St. Louis Metropolitan area. Due to increasing background ozone concentrations many plant species have become more sensitive towards ozone exposure. The purpose of an ozone garden is to examine how increasing background ozone affects plants in different locations around the St. Louis metropolitan area. We have found that those plants that are more sensitive to ozone exposure yield less whereas those that are more tolerant have a higher yield. With the soybean crop being valued in 2012 at more than $40 billion, even a decrease yield of a few percent could lead to more than $1 billion in crop losses.
