Re: [Aroid-l] 'Indian Giant' ploidylevel [was :Re:
....already more than one year ago I compared the ploidy level of
a normal form of Typhonium venosum.... with my 'Indian Giant'
However, I did no chromosome counts, but if 'Indian Giant' would be a
tetraploid of the normal form of T. venosum, the graph should
show a first peak at channel 100 for the G1-nuclei and a second
at channel 200 for the G2-nulei. This is not the case; all three
clones have the peaks roughly at channel 50 and channel
very interested in your results, but I admit I do not quite understand
exactly what is being measured in these graphs. Do these peaks
indicate the amount, weight or kind of chromosomal materials.?
really say there is the same quantity of genetic material? If so it
does suggest that all three are genetically quite similar.
it just say they have the same kinds of chromosomes and does not give
a quantitative measure?
exactly does this show. ?
there 2 peaks?
your photos of dormant bulbs. I didn't realize 'Indian Giant' could
reach such proportions!
Thanks for the info.
and thanks Jim W.
