Abstract

Naphthaleneacetic acid (NAA) sprayed as a 1% ethyl ester or sodium salt formulation below the grafts effectively controlled trunk and limb sprouts on topworked fig trees (Ficus carica L.). Reduction of scion growth and numbers of sprouts on unsprayed portions of grafted limbs indicated translocation of NAA for a distance of at least 10 cm.
