Rose Hybridizers Association Forum

I think where they went astray was in accepting Zizhi as being "R rugosa" even while knowing that it is a hybrid. I'd say that's more a failure of the typical rose classification which bins things into groups that carry species names even when we know they' re hybrids. And secondarily that during tr...

Videos like that really recharge my battery. Good to see that someone is doing effective science communication. Now if they'd make one explaining how plants resist blackspot.....

Thank you David for a very clear description of the bad news. And the possibility of some good. Happy Thanksgiving holiday weekend. Yesterday I had some time to sort roses for winter storage (putting pots below ground level and adding leaves). Came a cross a young bush in the making, of Brite Eyes x...

Very good David. I'm glad the ARS notices rose breeders who aren't corporate employees.

I especially like the yellow. Does it keep its color better than Carefree Sunshine and Carefree Sunshine? Fading is the thing that's gotten me with those as parents. No duration of bright yellow before it goes to white in OP and many crosses. So far my best yellows come from First Impression and Soe...

Don't have much of interest to report on Brite Eyes. Only one seedling so far has made it into my book of numbered plants. That was a yellow single with a red edge that develops in sun. I do have one or two seedlings each with Austrian Copper pollen or R pomifera pollen. Waiting for those to bloom. ...

Brite Eyes has been good rose for me so far, thought not so hardy as I'd like. I was surprised that both it and High Voltage froze nearly to the ground with a -10 F chill a couple nights. Reasonably fertile, tested only as female so far. Only problem is that it tends to singleness and the pale cente...

Sorry i wasn't clear enough. I didn't mean that simple hydration (imbibition) would split achenes, but the swelling that results from the uptake of water during the initiation of germination. That is when the cotyledons begin to enlarge so that they can open out, turn green and begin photosynthesis....

I doubt that amylase would have any effect on anything because there is no free starch in the achene outer coat. It is all pectins of one sort or another at the suture. that requires a pectinase such as the drisilase mixture contains. Lipase would not likely get into the actual seed coat. I have no ...

My observation, lots of botanists are a bit rrrright or lefffft of center. We've had a few here at K-State. Wisconsin has had more than their share through the years. For instance Hugh Iltis (evolution of maize) and Folke Skoog (M.S. medium).I see that Gilroy was educated at Edinburgh.

I think I've located it. Give me a couple days + your e-mail address in a P.M. to ldavis located at ksu.edu

Yes, Karl, you are absolutely correct on the likelihood in small samples. But until Gosset, no one knew that, at least in a simple way. And Mendel only looked for regularity of pattern, not quantitative evidence. For the large majority of small samples he would be close enough to convince himself an...

Karl, I'm not sure I agree with you about Mendel. He studied physics at a very good university in Vienna and had a good grasp of the statistics of his time. But they were Bayesian. If you know a prior probability, you can with some reasonable confidence predict the next outcome. Like the probability...

Thank you Don for saving me the effort of searching for this. After our library fire it is a challenge to get off-site items brought back to scan.

Maybe they forgot to mention that the key ingredient here is actually zinc cinnamate produced when the nail leave some zinc that reacts with the active ingredient in the cinnamon. If someone will send me a dozen roses, I'll provide the spuds and do a completely blind test of zinc, iron,copper and al...

This does make me just a little nervous. AS I mentioned on a thread earlier this year, I got Easy on the Eyes for $4 at Menards ( a big midwestern hardware chain). They had 2 whole pallets, at least 2 cu yd deep boxes, full of bagged roses labeled # 1&1/2. But what I bought looked like it was #1 gra...

I can see that beating mite eggs is really hard. And unfortunately the microwave will not kill the eggs directly, just as it won't kill cockroaches. They have to be poached by the steam or directly hard boiled. Sometimes quick-freezing will kill insects, though the eggs may be full of antifreeze mol...

Back a few decades ago someone named Joe Kuc (not sure of spelling last name) discovered systemic acquired resistance in plants. He was a plant pathologist in Kentucky and came here to give a talk in our PlPath dept. I visited with him for an hour or so. In the instance he was studying the resistanc...

My usual problem going from outdoors to indoors is spidermites on roses. Thrips can be a problem with other plants but doesn't seem to be much with roses, other than eating pollen. I just whack the plants and let them grow back outdoors while the cuttings are under lights in a nice, "sterile" pottin...
