Figure 4.

Pairwise Pearson's correlations among inbred line mean flowering time traits and fruit production for (A) North American and (B) Eurasian lines of Arabidopsis thaliana in a common garden experiment in Toronto, Canada. Correlation coefficients are shown for significant correlations only. In North America, three traits demonstrated significant correlations with fruit production, while no traits were associated with fruit production in Eurasia (dotted line). Underscored correlation coefficients are significantly larger than the same coefficient in the alternate geographic range, as determined by two-tailed Z-tests.
