Abstract

Vegetative propagation of cuttings is a widespread method to multiplicate plants. Adventitious root formation is a key step in vegetative propagation and considerable progress has recently been made in understanding root formation. But, in spite of the efforts made, no new rooting treatments have been developed. Here, we report for the first time, that N,N'-bis-(2,3-methylenedioxyphenyl)urea and N,N'-bis-(3,4-methylenedioxyphenyl)urea enhance adventitious root formation in microcuttings of Malus pumila Mill. rootstock M26. Roots emerge without auxin supplementation in the darkness, transfer in hormone free medium, or callus formation. With the use of different bioassays, we also demonstrate that these two diphenylurea derivatives do not show cytokinin- or auxin-like activity.
