Duckweed populations growing in Erlenmeyer flasks.
Scatter plots show no strong relationship between R* and maximum growth rate across duckweed genotypes in either benign or stressful conditions.
A plot shows that there is some variation in R* across genotypes, but this variation is suppressed under stressful temperatures.
On the top shows a scatter plot of duckweed population growth rates against nitrogen concentrations for both benign and stressful temperatures. Growth rates increase rapidly but flatten at high concentrations. On the bottom are plots that show R* values are greater under stressful temperatures compared to benign temperatures.
