The jade vine (Strongylodon macrobotrys A. Gray), is native plant from Philippines. It has long blue-green pseudoracemes inflorescence, which makes it unique and incomparable. It is considered one of the most admired and sought vines, although rare in gardens. This study evaluated the effect of indolbutiric acid (IBA) on the stalks rooting of this ornamental specie. Stem cuttings without leaves and with a couple of leaves cut in half, were collected from branches of a well developed jade vine plant and were immerged into dipping solutions with a concentration range of IBA (0, 500, 1.000, 2.000 and 4.000 mg L-1) for 15 seconds. Subsequently, the bases of the cuttings was planted in polystyrene trays containing vermiculite (one cutting per cell) and maintained in an intermittent water mist chamber for a 80 days period. Then the percentage of stem rooting was assessed as well as the number of roots and the length of the main root. Jade vine plants can be produced byr stem cutting treated in a dipping solution containing an IBA concentration of 2.000 mg L-1.
