Studies on the adhesive Conditions of Parthenocissus tricuspidata

Abstract

We made field experiments on the adhesion of Parthenocissus tricuspidata Planch. to a wooden wall, which is one of the most popular adhesive climbers in Japan. Experimental conditions were made by controlling the inclination of stern, the diameter of stern, the amount of insolation, and the concentration of gibberellic acid applied.
The result was that the degree of stem inclination, the diameter of stem, and the amount of insolation stlongly affected the adhesive intensity of P. tricuspidata, and the application of gibberellic acid had a little effect on it.
