Changes in the content of soluble sugars and starch were determined during the first phase of de novo organogenesis in stem internode segments (SiS), taken either from control plants or from the plants grown on medium with 10-8 M paclobutrazol (PBZ). **sient accumulation of soluble sugars was observed in both variants during the first two days. Control SIS accumulated higher amount [22.0 mg g-1(f.m.)] of soluble sugars than the PBZ pretreated SIS [15.2 mg g-1(f.m.)]. PBZ variant showed four times hi**r starch content at the start of experiment in comparison with the control. Both variants accumulated starch during cultivation until the beginning of regeneration.
