Quite right. The presence of auxins in the growing points (stem
tips -
flower stems or leafy stems) is not massively affected if they are
cut
from the plant and the same processes continue, albeit on a reducing
scale as the cut material deteriorates.


Thank you both. Now I've got the answer I was looking for - it's very
interesting, too. There must be some reverse effect that prevents
e.g.
Dahlia buds opening once picked?!

I am told that dahlia buds will open if they are showing colour when
cut.

My experience is that they have to have started opening, yes. But they
won't open at all if still tightly shut.
