Mean length and mean seed content of female cones harvested in five maritime pine mother trees after open (sampled in 2012, 2015, and 2017) and controlled pollination (sampled in 2012 and 2017). Data, are means ± standard error of at least three cones. Within each column, values followed by the same letter did not differ according to the Mann–Whitney U-test.
