Abstract: The possibility of regulating productivity of potato plants by applying the promising analogues of auxin – compounds TA-12, TA-59, LN-14, LN-16 – has been proved experimentally. The compounds at optimal concentrations (TA-12 1.0, TA-59 0.5, LN-14 and LN-16 1.0 kg/ha) were found to activate the process of tuber formation, increasing the number of tubers and accumulation of assimilates in tubers. TA-12 is characterised by the highest activity: it increased the productivity of potato (~ 6.0 t/ha) as well as sugar-beet root yield (~3.0 t/ha) and sucrose content (~1.1). TA-12 is supposed to affect plant cell through the IAA receptory system.
