Table 5.
Univariate association analysis. Significant associations with epigenetic loci produced from primer combination 1. We used α = 0.1. P-values are in parentheses beside the test statistic. Glucosinolate level (GS) and carbon isotope ratio (δ13C) abbreviated. 1Tests conducted from samples in offspring drought treatment only. Null hypothesis for each test i rejected when P(i) < (i/M)α, where M was the total number of polymorphic epigenetic loci (Simes 1986).
