Abstract

The effect of the compound TA-12 (1-[2-chloroethoxycarbonylmethyl]-4-) naphthalene sulphonic acid calcium salt) on the rooting of difficult-to-root cherry (Cerasus vulgaris Mill.) cv. 'Zagarvysne' and various cultivars of hazel (Coryllus avellana L.) green cuttings was studied and compared to the activity of indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA). Under the effect of TA-12, IAA and IBA, cherry 'Zagarvysne' cuttings undergo complex anatomical and morphological changes in the basal and subbasal parts. Using wheat coleoptile cell plasmalemma as a model test object in IAA investigations, it was shown that TA-12 could be percieved in the plasmalemma under conditions similar to IAA and transduced to the nucleus. It is supposed that TA-12 can affect the plant cell through the IAA receptory system, but TA-12 is distinguished for having high activity in rhizogenesis of difficult-to-root cherry 'Zagarvysne', hazel 'Pervenets' and 'Akademik Jablokov' green cuttings, as compared to the activity of optimal concentrations of IAA and IBA.

Key words: cherry Cerasus vulgaris Mill., hazel Coryllus avellana L, indole-3-acetic acid, indole-3-butyric acid, rooting, TA-12.
