Re: Pollen Processing/Storage

Nat,

Would you see any problem with putting a few grains of Drierite right in each vial with the pollen?

Re: Magic Wand F1

Neil, I'm looking for a microscope, too. If you add a "9" to that $49 I've found one online. Then there's software for measuring objects. That would be a great way to analyze the ploidy of seedlings from triploids.

Informative web page

There is a lot of interesting info on this page. About halfway down the very long page are some annotated pictures of rose anatomy that would be very helpful for the beginner or people like me that can't remember the difference between a pistil and a stamen, etc. Later there is an interesting list o...

Re: Rain after pollination out in the field!!

George, I use parchment paper (baking paper impregnated with silicone). I roll up a little tube from a 3 or 4 inch square and slip it over the emasculated and pollinated blossom. I keep the sepals on and try and fold them over the tender parts as I'm slipping on the tube. I position the blossom half...

Re: Q: on Private Messaging

Another thing I've noticed is that there is no way to get to one's inbox for PM's in this 'Ruby' layout. I have to click on a random person's name, click on "Send PM", and then click on the inbox over in the left-hand sidebar.

Re: Sowing seed in OZ

I know I shouldn't, I but I have to try picking off the achene covering. Sometimes I end up snapping the poor guy off below the cotyledons.

Re: Double Xanthina

I have 25 grams of xanthina seed on order from B & H seeds. I was planning to kill most of them with trifluralin. Maybe I'd better grow a few out (assuming I can get germination) and see what comes of them.

Re: Pollen Processing/Storage

Yep, my allergies are concurrent with rose pollinating season, and often it's really bad when I'm doing the pollinating, so I wonder if I'm not also allergic to rose pollen.

Re: A rant about those "bloom machine"- type roses!!

That's great info, Peter. Thanks. It explains why so many Baffin seedlings are non-remontant. A fair percentage, though, are very everblooming, so it must have some genes for remontancy.

Re: What is "F1" "F2" stage?

Correct me if I'm wrong, gentlepeople. It's just an easier way of saying "first generation" and "second generation", etc. Any time one makes a cross, the first generation of seedlings is called F1, and the seedlings of those F1 plants are called F2 (I think whether they are self-pollinated, crossed ...

Re: A rant about those "bloom machine"- type roses!!

OK, there are many people here who actually know things about this, but I'll throw in my amateur understandings. Tetraploid roses do indeed need all four genes to even consider being a repeater, I think. It's all very interesting. Why are there some roses like William Baffin (very weak repeat if any...

Re: What diseases are passed on

I'm still optimistic about my Prairie Sunrise seedlings. The emerging true leaves seem normal, and I'm really curious what it's characteristic of huge double blossoms will do to crosses with something like my KO X W. Baffin that has tons of smaller single blossoms. I think I have a couple of Distant...

For the last two or three years we've been getting our commercial germination mix (Berger BM2) with some sort of natural fungicide...it might be Actinovate, but I thought it was something with copper or iron...I can't remember or find the details right now. Previously we treated all of our germinati...

Re: Genetic Incompatibilities - Or, Just Damping Off?

Interesting! In regards to the cotyledons-only seedling, that happens quite a bit and I don't think it will ever be able to push out true leaves....I think the genes just don't line up. I don't have any insight on the damping off, though. Genetic incompatibility makes perfect sense for the seedlings...

Re: Aphids...dang!!

Marathon, or Mallet. You'll have to google it for the active ingredient to see if it's available in OZ.

Works like a charm, won't hurt the plants. I'm all for organic solutions, but in the greenhouse biz we can't mess around because aphids get out of control so fast.

Re: What diseases are passed on

This year I have a few seedlings with an apparently virused Prairie Sunshine as the seed parent. I noticed that many of the cotyledons were a little wrinkled, which looked like a virus symptom. The first emerging leaves have not yet shown any symptoms. I'm going to keep them...who knows, if there is...
