Cryptostephanus DNA
James Waddick (Mon, 22 Nov 2004 18:31:55 PST)
All had nearly the same value 44.6 picogram DNA per nucleus.
However a ""typical but large leaved white flowering form of J
Waddick had 36.4 pg This suggests that it a = hybrid b.= a new
species.
Dear All;
I do not know the karyotype or chromosome number of
Cryptostephanus. I was wondering if the typical form is a natural
tetraploid and my odd plant might be a triploid. The ratio of DNA
(44.6 versus 36.4) is close enough to suggest that. Does anyone know
the ploidy of this species?
Another odd thing about this 'off reading' is that the plant
in question is considerably larger in stature than my 'pink form' or
another typical white seedling. I'd think a tetraploid might be
huskier than a triploid, not the opposite seen here.
What might be happening here?
Thanks Jim W.
