We used t-test to assess the difference in cell number per
100 mm2 in sclerenchyma tissue from BPP and normal stems. We
used two-way ANOVA to test for differences in auxin levels
between stages or between upper and lower parts of peduncle
segments. Analyses were done using SYSTAT v. 11 (SYSTAT
Software Inc., San Jose, CA, USA). We used a G-test of independence
[25] to test for an association between the bending state of the
main and axillary inflorescences in each treatment (control, IAA
and NPA) separately.
