WebThe photo- tropic curve is from Shropshire and Withrow (1958) for Avena. The red induction and far-red reversal curves are from Withrow, Klein and Elstad (1957) for the hypocotyl hook opening of the bean seedling. All the curves have been adjusted to an arbitrary value of 100 units response at the peak.
