SUMMARY Hypocotyls of embryos from unripe and soaked ripe seeds of Phaseolus vulgaris and Acer pseudoplatanus are shown to be capable of transporting auxin. The transport is strongly polar and shows the characteristics of active transport in the basipetal but not the acropetal direction. A procambial cylinder and a few phloem elements have been formed in these hypocotyls.
