From: Distinct transcriptional profiles of ozone stress in soybean (Glycine max) flowers and pods
The effect of O 3 on the number of flowers and pods produced per node in field-grown soybean. (a) Linear regression of the average number of pods per node for soybean plants grown under eight [O3] at the SoyFACE facility (http://www.igb.illinois.edu/soyface/) in Champaign, Illinois in 2009 and 2010. Blue lines show the 95% confidence intervals. Experimental design, planting conditions, meteorological data and harvesting methods are found in [27]. (b) Average flower number per node for soybean plants grown under ambient (44 ppb) and elevated (100 ppb) [O3] at the SoyFACE facility in 2011. Flower number per node was monitored daily for five plants per ambient and elevated [O3] plot (n = 2 for ambient, n = 4 for elevated [O3]).
