In vitro cultured tomato seedlings were micropropagated using the single-node method. By periodically subculturing single nodes and shoot tips in vitro, tomato progeny were obtained that arose from axillary buds (nodes) 1 (base) to 9 (top). Rooted shoots were transferred periodically to soil and were grown further in a greenhouse to observe flowering. The number of leaves preceding the first inflorescence in the various groups of plants was not influenced by the original position of the axillary buds on the main stem. Similar results were obtained in decapitation experiments in vivo. These results indicate that axillary buds on the main stem of tomato plants do not differ in their flowering behaviour.
