Re: How big is big enough? and how tall do they get?

From: StroWi at t-online.de (StroWi) on 2002.04.14 at 16:37:43(8543) Randy, I think this is something most Amorphophallus growers are interested in. The list you propose is a very good idea! I would like to take the chance to add the question how tall they get at a definite tuber size (lets say at good light and growing conditions): Would any one know, if there is a close correlation between tuber size and PETIOLE HIGHT in Amorphophallus titanum? If someone has figures or even an idea, I would be very intersted. (It could tell me when to built a higher greenhouse for my A.t. or do something different; see below) I ask this in the same context as I asked for the effect of growth retardants on the petiole hight of A.t. or other big aroids with a single leaf some time ago. I did not get a response when I posted my question, but I think it should work, since growth retardants generally inhibit cell elongation to a certain extent. (Normally they are used in horticulture to shorten internode length in ornamentals like Poinsettias and others) Looking forward to any comment!
