Genes survive, but they can be resegregated. Hybrids crossed, selfed, or
backcrossed produce this result. The F2 generation and further has all sorts of
results, not the even mixing of 2 parents in a primary hybrid. One particular
trait that is most desired can be had with the rest of the genetic makeup
resembling other species in the cultivars background.
Bonaventure Magrys in Elizabeth (writing from South Orange),NJ; where I've just
used the eyedropper method to put on Arisaema flavum pollen onto A.
saxatile(candidissimum pollen didn't seem to take) and onto A. speciosum.
Another speciosum bloom was male, spadix excised and refridgerated, awaiting an
A. intermedium. Happy endings.

Subject: Re: Hybridizing: honey solution
Regarding the matter of using a honey solution in breeding. The rational
behind its use goes like this. A 20% honey solution is painted on the stigmas
in order to ; give a sticky surface to hold the pollen in plaace ; provide
an enhanced nutritive environment for pollen growth; possiblly reduce the
concentration /effectiveness of any inhibitory compounds. Creative thinking
is needed in any breeding situation. For example, a friend who grwos palms
uses a Water-0 Jet squirt gun to shoot a mixture of pollen and water wtith a
bit of honey added to it in order to pollinate palm flowers 30 feet off of
the ground. It works! I use the same technique to fertilize orchids and
ferns high in the oak trees.
On the topic of hybrids:
Tell the collectors not to confuse the container with the contents. It's the
genes that must survive, not a particular phenotype.
