| Table 2. Mean numbers of female flowers per tree in Experiments 1–3. For tests of significant differences, LsMeans of transformed data (Transf) are presented for each experiment. Treatments with significant differences (p < 0.05) are indicated by different letters (significance test within experiment). Mean values calculated as LsMeans of untransformed data (Untransf) are presented to indicate the level of flowering and the magnitude of differences between treatments. | ||||||
