Cuttings obtained from young durian (Durio zibenthinus Murr.) seedlings rooted very readily. A histological study carried out on the rooting zone of these cuttings showed that cell walls of the derivative cells appeared relatively thin which probably is desirable for these cells to readily revert back to the undifferentiated state and ultimately become root primordia. It also showed that the stem had yet to develop any form of mechanical barrier that may restrict the development of adventitious roots.
