Abstract

Tip Nip^™ (undecanol) was applied to the potted chrysanthemum cultivar Mountain Peak at concentrations of 1.0, 1,25 and 1.5 percent as a chemical pinching agent. Treatments were sprayed over the apical region on the 4th, 7th, 10th and 13th short day. All rates successfully pinched treated plants when applied on the 4th short day. Plants treated on later dates exhibited variable response. There was no significant difference in height, spread, flower number, flower diameter, or number of breaks between plants chemically pinched on the 4th short day and manually pinched controls. Chemically treated chrysanthemums showed no delay in flowering. Tip Nip caused no injury to plants even at the highest concentration tested.
