Re: Worms eating seeds

I found the microscope. It was fascinating to look at the worms under the scope. Very smooth, with no sign of segmenting or the black head of fungus gnat larvae. Look very much like the Enchytraeus buchholzi mentioned above. Most nematode photos seem more microscopic. I wish I could have taken a pic...

Re: Worms eating seeds

Wow, thanks everyone for the replies! I can't find my darn pocket microscope, the use of which seems like a logical next step. Maybe I can capture a photo through it that will help us learn more. But the scope is likely buried under one of my piles of miscellaneous crap...the question is which pile?...

Re: Petite Knock Out Rose - AVOID

I hope Jonathan Windham doesn't mind me posting here what he wrote on Facebook, which is a good summary of the situation: Begin quote: Recently, Star Roses and Plants has decided to introduce the first rose ever to be covered under a *utility* patent. This means that no one will be allowed to use it...

Re: When to expect Rugelda F1 first blooms

Duane, I think Above & Beyond is one good path forward to combine yellow and hardy. Keep in mind it is not a reblooming rose and produces fewer than 1 in 6 reblooming seedlings when crossed with rebloomers. Therefore you have to grow larger quantities of seedlings from these crosses and cull to keep...

Re: Worms eating seeds

UPDATE: I’m checking on my other seeds and am seeing quite a few of the same worms here and there. These larger (non-poly) seeds appear to be unharmed. So maybe I was jumping to conclusions. My peat is not sterilized. The worms could just be in the peat and unrelated to the rose seeds. The poly seed...

Worms eating seeds

I’m stratifying in peat this year. My potted Pretty Polly Pink pollinations weren’t ripe when winter hit so I pulled the pots inside for a month or so to let the seeds ripen. David has mentioned that polyantha seed germinates better at a straight 50 degrees F rather than being given a conventional c...

Re: I'm confused: a diploid?

The Gruss an Teplitz parentage seems dubious for Wasagaming. Also for Yatkan, which is listed as possibly Gruss an Teplitz x La Mélusine (a rugosa hybrid) on HMF. It is curious how you could get an extremely cane hardy rose with that cross. And also a diploid, if Gruss an Teplitz is a confirmed tetr...

Re: tracking seed germination

Not adding much here: I remember two batches of R. foliolosa seed, pollinated by different parents, seeded in the same tray on the same day, germinating distinctly a few days apart. This would seem to indicate an influence of the male parent. However, the extra variable is hip ripening time. I didn'...

On the topic of Orangeade: Stoddard's article mentions its usefulness in accepting species pollen. Kim Rupert made the cross Orangeade x R. nitida, which he called Orantida. It was unable to bloom in his climate due to a lack of cooling, so he sent one to me and others (Rob Byrnes, I think). I kept ...

Re: Is every rose seed completely unique?

An important concept to learn when considering this topic is heterozygous vs homozygous. A heterozygous rose carries a lot of hidden gene characteristics that are being masked by dominant genes. A homozygous rose carries genes in which the hidden, unexpressed genes have quite similar characteristics...

Re: What is the easiest and hardest steps in rose breeding?

Culling is the hardest thing. Stratification and growing of young seedlings is more difficult than pollination. The analogy of making human children is apt. Pollination is easy and fun. You can get better at it with practice, but you don't need much skill to succeed. Germination is more difficult. S...

I like the extended, showy blossom display of this seedling. You can see the Prairie Peace, perhaps, in the flashing of...

Re: R. carolina video

Larry, Regarding Suzanne: The tendency of Suzanne and other spin hybrids to significantly defoliate, combined with their extreme thorniness, gives rise to prejudice in me. While carolina and virginiana don't have as extreme hardiness, their healthy, modern foliage and vigor make them more valuable p...

Re: germinations

Yeah, I had been leaving my seeds out at room temperature or a little colder on average. When I went through them several had sprouted...I'd say about 20 or 30. Luckily I have lights. I'm happy to have some little roses to watch during the winter.

I hope you can get yours to survive!
