The present study is concerned with auxin action in intact and excised 4th internode of tulip shoot after removal of the flower bud in relation to the growth stages. Elongation of the intact 4th internode with or without leaves, after removal of the flower bud, at different stages was very weak. This suggests that the flower bud is always responsible for elongation growth of the 4th internode. Auxin (IAA at 0.1%, w/w in lanolin) exogenously applied to the cut surface of tulip shoot with or without leaves, greatly stimulated the growth of the 4th and lower internodes of tulip shoot. The elongation growth of excised 4th internode of tulip shoot with or without node, after removal of the flower bud was much higher, in comparison with that of intact 4th internode in tulip shoot which was growing and in which the flower bud had been cut. Elongation depended on the initial length of the 4th internode. IAA at 0.1% applied to the cut surface of excised 4th internode, just after removal of flower bud, slightly increased the growth of the 4th internode. The promotion was observed only during the first or second day of the experiment. Finally, auxin did not stimulate, or had no effect on elongation of excised 4th internode with or without node. On the other hand, elongation growth of the excised 4 th internode with a flower bud was almost independent of the initial length of the 4th internode. Differences in the growth of excised and intact 4th internode of tulip shoot after removal of the flower bud are discussed in relation to auxin action.
