Abstract Young tomato plants were treated with foliar sprays
and root applications of aqueous solutions of methanol and ethanol.
Concentrations ranged from 5 to 20% v/v. Root applications caused severe plant
damage. In contrast foliar sprays resulted in significant growth stimulation.
Both alcohols increased leaf and stem fresh and dry weights with the maximum
increases at the highest concentrations tested. Methanol produced a greater
increase in stem length and stem fresh and dry weights than ethanol. There was
no signficant difference between the alcohols in terms of leaf weights or leaf
number.
