Table 3.

Correlations between the mean mass of 100 seeds (Mass) and seed hull percentage (Hull), mean initial germination proportion (Initial), mean percentage of afterripened seeds (AR), seeds germinated at low temperature (10 °C), and seeds treated with 1.0 mM gibberellic acid (GA). In each section of the table, the Pearson correlation coefficients (lower left part) and corresponding p values (upper right part) are reported. Number of observations n = 15, except in 2015, where n = 8 for 10 °C and GA treatments.
