help - ohio state viola research

dwhr(NH cool z4)January 17, 2007

Hello viola peoples!

I'm a new graduate student at The Oho State University in Columbus (Ohio, USA) and am developing a topic for my research thesis. Ornimental plant breeding is my line of work, and I'm quite proficient in dabbing hemerocallis (my true love), hosta, and am expanding my tastes :)

Anyway, I am interested in examining DNA fingerprints of (Ohio) naive species, in order to try and connect them to common ancestors. I am having a heck of a time finding in formation on chromosome counts of all the species I have (not all natives):

bicolor

blanda

canadensis

cornuta 'Black Magic'

cucullata

dissecta

gracilis

hastata

hederacea

hirsutala

labradorica

labradorica 'alba'

laceolata

macloskeyi

o. 'Rosinia'

palmata

palustris

papillonacea

pedata

pinnata

pubescens

rostrata

rotundifolia

'Royal Robe'

sagittata

sororia

sororia 'freckles'

striata

triloba

Any chance anyone here can help me out -either digits or maybe a reference or referral? I have checked some peer-reviewed literature, and most recently the "Chromosome Atlas of Flowering Plants" by Darlington and Wylie.

Thanks,

Dan

OSU grad student

Hi Dan
What I have on my side:
In Landon and Mc KinneyA taxonomic revision of the acaulescent blue violet 1992:
cucullata 2n=54
hirsutala 2n=54
palmata 2n=54
papillonacea 2n=54
pedata 2n=56 ( gershoy 1934)
sagittata 2n=54
sororia 2n=54
triloba 2n=54
+ found on the web
Canadensis 2n = 24 ((Clausen 1929; Canne 1987).

but in Ohio you have no less than Harvey Ballard and Theresa Culley!!!!hey!

keep us informed about your researches
cheers
