Abstract: The rooting substances of tomato ( Lycopersicon esculentum Mill.) explants during root regeneration were studied. The root-promoting substances of the basic, acidic, and bound ether-soluble fractions of the plant extracts after paper chromatography were determined by a tomato hypocotyl test. The basic root-promoting substances in the basal hypocotyl region changed qualitatively, while those of the acidic and bound fractions decreased with rooting. It was found that in 5-day-old explants, the highest root-promoting substances were in the bound fraction, and in the basal hypocotyl region. Histological evidence showed the presence of preformed root primordia in the rooting region of 10-day-old tomato explants.
