Girdling and Applying Chemicals Promote Rapid Rooting of Sycamore Cuttings

Abstract

Shoots of 6- and 13-year-old sycamore (Platanus occidentalis L.) were girdled and treated with rooting powder 4 weeks before cuttings were taken. The powder, which contained auxins, sucrose, and cap tan, was also applied basally to nongirdled cuttings immediately before iwertion in a rooting medium. Thirteen days later, 100 percent of the girdled cuttings had rooted; they produced an average of 21 roots per cutting. Only 22 percent of the nongirdled cuttings rooted during this period; the average number of toots per cutting was four.
