Propagation of Amorphophallus from leaflet cuttings

From: markdim at azstarnet.com (Mark A. Dimmitt) on 1999.04.08 at 13:32:32(3245) I haven't tried petiole sections, but I did take a number of leaflet-tip cuttings in January 1998 from freshly-matured leaves (after someone else on this list reported a not-quite successful attempt). All callused and rooted readily. One of the two clones never sprouted a leaf. Two of the six cuttings of the other clone have sprouted leaves and made tubers. It took a full year, as long as germinating seeds. One cutting made three leaves and tubers though. +More Try it with fresh leaflets 10-20 cm long. I did some in water, some in vermiculite-perlite. All were kept at 30 degrees C and high humidity. Rooting hormone didn't seem to make any difference, but maybe a shoot-inducing hormone would help if there is such a thing. *************************************************************** Mark Dimmitt Tucson, Arizona USA Business e-mail: mdimmitt@desertmuseum.org ***************************************************************
