Table 2.
Mean number (±standard deviation) of galls and seeds per inflorescence or infructescence in Thaumatophyllum bipinnatifidum across different treatment combinations. n is the number of examined inflorescences, and NA indicates the treatments for which, by definition, the data were not available.

* Due to inflorescence abscission, the treatment results were unbalanced across the experiments conducted on the nine T. bipinnatifidum individuals. Consequently, a mixed-effects model approach could not be applied to the data analysis. Therefore, n represents a combination of biological and technical replicates.
