[aroid-l] A. Titanum cloned

From: "WEAVER,BILL (HP-USA,ex1)" bill.weaver at hp.com> on 2003.09.15 at 22:21:30(10581) A year or two ago there was some discussion on the list as to whether Amorphophallus titanum could be successfully cloned from a leaf cutting. So I decided to give it a try. I took two leaflets off of the big leaf and treated one with Rootone F and one with Olivia's Cloning Gel. Each leaf was then put in a six inch pot full of seedling mix (fine vermiculite/sand/perlite) and zipped into a plastic bag and placed under fluorescent lights. The leaflets stayed green for almost a year. After they died and rotted I strained the potting material I found something pretty cool. The Rootone treated leaflet had produced three tiny bulblets, the largest was about 9mm and the smallest about 3mm. The Cloning Gel treated leaflet produced the most interesting growth. The midrib of the leaf had produced two cylindrical growths, the smaller one was about 2.5cm long and about 7mm wide. The other was over 6cm long and 2cm wide. Attached to it were two small bulblets 5mm and 15mm in diameter. I planted all of the bulblets and growths in April 2003 and the first new growths sprouted from the Cloning Gel pot this weekend. To put it mildly I am very happy with the results and decided to share the story so far. Bill Weaver +More bill.weaver@hp.com
