A simple and efficient organogenetic mechanism of shoot regeneration has been detected in egg plant (Solanum melongena L.) and in tomato (Lycopersicon esculentum L.). Seedlings raised aseptically on hormone free MS (1962) medium were decapitated by the 6th to 18th day. Shoot buds developed freely after 5–10 days on the cut surface of the hypocotyls. Shoots isolated and cut into pieces by different ways after the subsequent 10–14 days, are put on hormone free MS (1962) medium. Those explant grew into rooted plantlet. The present Seedling Decapitation Method (SDM) has been optimized for tomato and egg plant, two varieties of each. Depending on the variety, SDM produced 3–30 shoots i.e. rooted plantlets on each seedling within six weeks. It seems that the SDM offers a new means in theoretical research as well as in practical plant biotechnology and breeding. Results and potential applications are summarised and discussed.
