Root squash ploidy technique

I am posting rather than PM'ing David thinking that other's also might benefit...

I believe that David had posted his technique, perhaps on the old forum, but I neglected to bookmark it, and cannot find it in a search. I wonder if someone could either recap, or post a link to the techniques for determining ploidy of a rose.

I'm specifically curious about my... er... yellow, climbing, semi-mini, apparently-wichurana-derived rose called 'Presto'.

As an aside, I wonder what folks would think of a rose-hybridizer's wiki associated with the RHA. It could serve as a good permanent repository for techniques and information beyond the few links at the RHA site. Using Wikimedia, it reads like it wouldn't be too difficult to set up.

Philip,

David's article on the root tip squash method for counting ploidy appeared in the Spring 2004 issue of the RHA Newsletter, pp. 14-17, with pictures. If you have that issue or the compilation CD, you can read the full article.

Apparently the forum search utility is not working well right now. If you use Google and input this (root tip squash site:rosebreeders.org) as your search, you will find what you were looking for on the forum.

The current forum has all or nearly all the content of the old forum.
