Influence of STS and ethephon (eth) on leaf area (A) and root dry weight (B) in wild-type (cv Ailsa Craig) and transgenic (ACO1_AS) genotypes of tomato grown in 1.1/1.5-g cm⁻³ split-pot soil columns. A, Black columns, split-pot; white columns, STS; hatched columns, ethephon. B, Total root dry weights and their distribution between the 1.1- and 1.5-g cm⁻³ compartments; the shaded areas denote roots in the 1.5-g cm⁻³ compartment. Single ses are shown. White/black bars, Split-pot; white/stippled bars, STS; white/hatched bars, ethephon.
