  • a All trichomes on rosette leaves 3 or 4 were measured from at least two different plants per line. Data shown are average (μm2) ± sd (median).

  • b Median trichome area and median DNA content as determined in this study (Figure 2) were used. The Landsberg erecta area-to-DNA ratio was set to 1.
