Rod,
I terminated my attempt for now because of the seed I was using-it might take two years for any of the traditionally stratified B.Boop seeds to germinate, if ever. And I tried this in such an afterthought sort of way. I will try this next year with a few more seeds-which I did think I would have until I cleaned the seeds. And with a type of seed that I might want to use. Maybe even some B.Boop crosses with another rose-not B.Boop OP seeds. The reason for this is that I was looking at the last two years of my germination records and I noticed that many (definitely not all)open pollinated seeds do not germinate as well as the crosses. When I calculated the % of germination overall of all the seeds I had collected and stratified two yrs ago, it was 27%. Many of the OP seeds had little to no germination, and when I eliminated those from the over all number, the rest of the seeds had a 39% germination. I used less OP last year and even less this year, but still the number of germinations are less among the OP’s. This may be related to the varieties I have because some OPs germinate well, although some of these are one’s that might be more easily insect pollinated, because they are semi’s and singles. Anyway, I want to try with a type of seed that might have more uniformity, to lessen the possibility of some being various crosses, or selves, as B.Boop I think would be easily pollinated by bees, and there might be great variability in the germination just based on that, and I didn’t mix the whole group of seeds. Also, the seeds did get pretty well “acid etched”, but not nearly as much as the seeds that Simon used. I did not use enough tomato.So I will try again, but with a few more controls and a little more prep. No more germinations have happened with any of the seed.
