Any other information on results incl. tables

Isolated wheat roots in light and in the presence of iron show a marked inhibition of the cell elongation. This inhibition is reversed by some primary alcohols and cell length is restored. However, Methanol examined has very little or no effect, either in light or in darkness. No toxicity of Methanol was observed.
