Abstract

THE difference in growth rate of the two sides of geotropically reacting plant organs is generally explained by the well documented unequal auxin concentrations in the two halves. The auxin ratio in horizontally placed stems, coleoptiles, and roots usually attains a value of about 2:1 in favour of the lower half.
