Victoria,

Your greenhouses must have been in bizarro land. The situation is exactly
the opposite as you describe. A rooted cutting is a clone.

beeky,

This depends how you define "clone". If you hold that the horticultural meaning
is that a clone is the descendant of a single plant by vegetative reproduction,
then a rooted cutting would be a clone.

If you hold that the horticultural meaning is that a clone is the descendant of
a single plant by vegetative reproduction which has the identical genetic
makeup and attributes as the parent, then specific tissue from the parent may
be required. i.e. African Violet chimeras can't be cloned true to form
through rooting leaf cuttings. Either suckers are induced, or specific tissue
from the parent is used in the propagation of genetically true offspring.

Regards.

OOPS! I was off by 15 years. Here are the references for the word
"clon" that I was talking about-

interesting 'obscure' topic anyway.

YES!!! You rock! This reference is exactly what I was looking for.
Thank heavens for obscure references. 8^)

Let me know if I can ever return the favor.

A clone is genetically identical to the mother plant. The method of propagation
does not factor into the definition.

In general, a rooted cutting is a clone. However, as you noted, there are examples
of rooted cuttings that are not genetically identical.

The term is "clone" and basically just means taking a cutting to produce a
clone of the original plant with the same genetics and attributes.

Not always and not usually. Clone of plant matter is generally done by
selective tissue culture. It's a bit different than taking a cutting.



Then please explain to us how a cutting can change the genetic material of the
plant, so that it won't be a clone.

You are not "cloning" when you do that. You are propagating by cutting. There
is a scientific difference and the process is entirely different. Cloning takes
whatever sport of whatever plant you are using and reproduces it's exact
properties, while a cutting can revert.

Chimeras have more than one genotype (genetic makeup), and challenge
what we generally consider to be a horticultural clone. A descendant
of a chimera may contain the identical genetic makeup of the parent
plant, but depending on how the "clone" was propagated, its attributes
may be unstable. I think that was Victoria's point with regard to sports,
and why the industry uses tissue culture to ensure the anomaly is passed
on reliably.

You all could read the articles that were cited and then resume you argument.

Or not bother and move on to someting else!
