Relationships among fertilization treatments and chemical traits of Carex filispica, described by Pearson correlation coefficients, separated by Dauciform root (DR) presence. AOC, aboveground organic carbon; AN, aboveground nitrogen; AP, aboveground phosphorus; BOC, belowground organic carbon; BN, belowground nitrogen; BP, belowground phosphorus; + DR, individuals with dauciform roots; − DR, individuals without dauciform roots. * indicates a significant correlation (p < 0.05).
