RE: [Aroid-l] Leaflet use for tuber production.

From: "D. Christopher Rogers" <crogers at ecoanalysts.com> on 2007.01.24 at 18:14:41(15128) Howdy! At the University of California, Davis Conservatory we have propagated Amorphophallus titanium from leaflets. The guy who developed the method there is Ernesto Sandoval. Best results are obtained from terminal leaflets with a petiole about as thick as your index finger. The lamina is stripped from the portion of the petiole to be buried. The medium is vermiculite/perlite, and it is important to keep them upright, even propping them up if necessary. They are treated with a low dosage hormone (Rootone F), given plenty of bottom heat and high humidity. I hope this helps, Christopher +More D.

Dear Friends, It is well known that in a couple of genera of aroids, the shed or knocked-off leaflets can and will grow into new plants. The two best known examples are the notoriously weedy and invasive Gonotopus boivinii ( I wonder if this is the only species in this five-species genus that does this?), and to a lesser extent its relative, Zamioculcas zamifolia. I am looking for any and all information on how sucessful reproduction or multiplication has been achieved in OTHER genera of aroids by using small cuttings or portions of leaf (like it has been done in Amorphophallus titanum). Information which I need should include the aproximate age/condition of the leaf cutting used, the names of rooting hormones/powder that may have been used to coat the cut ends of the leaflets, and importantly what genera and species of aroid has this method been attempted with, and which were sucessful at acheiving rooting and new tuber/corm formation. etc. I THINK that there has been information published on this, perhaps in a back-issue of our Aroideana, so if possible I also like information on when/where any publications concerning this method have been published. Please contact me off-line if you are more comfortable with that. Thanks a million.
