Trichome production of cytokinin-deficient line 35S:CKX2 and spindly3; only organs showing a significant difference between the genotypes are shown. 35S:CKX2 overexpressors only produced two cauline leaves under our growing conditions. Sepal trichome values represent the number of trichomes for a total of ten flowers. Branch trichome values are the total number of trichomes for the chosen internode. Values represent averages and standard error (in parentheses) for 20 plants.
