Chapter 4 154 Figure S4.4. Stem responses to different IAA concentration by brushing treatments applied on internode 1. We treated 14 day-old tomatoes with different concentration of IAA by brushing onto internode 1. Brushing was applied 3 times over one week treatment period. The data include measurements of (a) stem length, (b) hypocotyl length, (c) hypocotyl diameter. The data are presented as mean ± SEM, and different letters indicate significant differences between treatments based on ANOVA analysis with Tukey’s post hoc test (P<0.05). There were 12 biological replicates, and the experiment was repeated twice.
