Don 2009 Late Crosses

Don, You mentioned in a previous post that you continued to pollinate right through the hot summer months last year. How did that work out for you?

Hi Bill,

It generally worked out well, thanks for asking. It may not be possible to see the effect of summer heat on pollination, though, because we really didn’t have much in the way of high temperatures. My gut feeling is that the amount of time between pollination and harvest is much more important than temperature.

The last batch of embryos have just been put into culture and I am finally getting around to trying to sort the results. For now all that can really be said is that enough viable embryos were obtained to justify the effort. There will be plenty to write about in a future newsletter, including what was learned about the maturation of rose embryos and the benefits and limitations of embryo culture in such cases.
