General Discussion / Re: Plants in the News

Botany Manor, Xbox Series X

"One game I wolfed down in a single evening recently was Botany Manor, a sedate puzzle game about growing all sorts of weird and wonderful plants inside a picturesque Somerset stately home. These aren't your typical roses and daffodils, though. Rather, these rare and exotic strains will only bloom under very specific circumstances - the right room temperature, say, or having its soil juiced up to a particular pH by crushing certain apple varieties into it. My favourite was the Wolfglove, which only bursts into life when you recreate specific sounds and wind speeds inside an old tower to mimic the environment of its mountainous home."

Oron replied:

"Not sure  what his reference is...
According to Kew which is the authority, it is in Spain and the Canary Islands as well.
The photo i took in habitat was in a population of hundreds of specimens all yellow, it wasnt only one plant.

Quote from: Carlos on December 06, 2024, 01:48:14 PMD. fulvum is North African, about two to three times as big and DOES NOT occur at all in the Pyrenees. Oron Peri just saw a plant with yellowish flowers.

The wiki says:

The two photos were taken in its habitat in the Spanish Pyrenees by Oron Peri.

Maybe I could say:

The two photos were taken by Oron Peri.


I have contacted Oron, we'll see what his reaction is...

Quote from: Too Many Plants! on November 19, 2024, 01:37:12 PMif you're asking me if you can use my photos, absolutely fine with that. I can try and find some past pics of my flowers too.

Thanks. There are some forum flower pics here, question is of which one.

Quote from: Carlos on November 18, 2024, 12:52:24 AMthose are Drimia numidica.

Seemingly it was once Urginea maritima var. numidica

What do you think the photos on the wiki are of?

https://www.pacificbulbsociety.org/pbswiki/index.php/DrimiaSpecies#martima

How do you tell the difference?

I'll do a wiki entry for numidica using the photos from here if that is OK? Or feel free to send in photos.

Quote from: CG100 on November 16, 2024, 12:03:29 AMBut many viruses are carried in seeds

Yes, no argument from me now. I was merely pointing out that before this discussion I had a different (incorrect) point of view.

Quote from: CG100 on November 15, 2024, 02:07:41 PMWhat virus?
At least some can be and certainly are.

Any virus present. It is common to read that seed grown lily plants are virus free, for example this quote from the RHS lily group:

They can, of course, be raised from seed which has many benefits. Not least of these is avoiding the transmission of viral diseases.

I believed this and thought the way to a virus free lily garden would be to grow it from seed. Perhaps lily seed is more virus free than other seed.

Quoting Google AI (which is becoming more erratic by the day)

No, seed grown plants are not always virus free
A small number of plant viruses can be transmitted through infected seeds or pollen. In fact, about one-third of plant viruses are seed-transmitted.



There is an interesting paper:
Transmission through seeds: The unknown life of plant viruses

The PBS wiki says:

"With a few exceptions, the most reliable manner in which to obtain virus-free stock is by germinating ones own geophytes from seed."

It then goes on to list viruses, stating which ones are not passed on via seed.

Quote from: Bern on November 15, 2024, 11:51:20 AMWish me luck.

Good luck.

Virus would be a good research project for the PBS to fund - examine someone's bulb collection and report back on what has virus and not.

Lilies are a bulb that has virus problems - some are tough enough to not show any symptoms others succumb easily. Propagation by seed does not transmit the virus, then there are ways of propagating them without propagating any virus.

"Virus Yellows disease, a complex of three viruses transmitted by aphids, reduces the photosynthetic capacity of sugar beet leaves, which in turn reduces the sugar content and yield of this crop. Historically, Virus Yellows has been controlled by neonicotinoid seed treatments."

and bee lovers dislike neonicotinoids.

I wonder where the virus came from. What would make a nursery able to avoid a source that you could not. How would you get rid of a reservoir of it.

Cheery questions 8-)

Seemingly you could pay to have the plants tested for virus [1] - about $100. Maybe cheaper to buy new plants. Interesting that there are cheap lateral flow tests for plant virus's - but points to the fact you have to know the type of virus.

Electron microscope images of the virus would be great addition to the PBS wiki.

Quote from: CG100 on November 11, 2024, 11:47:34 PMit needs a sap-sucker to move the virus around between plants

Yes, but they are all too common. I imagine they like soft leaves more than hard glossy ones.

seemingly the leaves are sensitive to changes in the environment.

Quote from: CG100 on November 09, 2024, 12:05:07 AMthe US has Lieutenant, the UK has Left-tenant,

Not that it matters but the US pronunciation is the original. Whenever there is a US/UK difference the way to bet is that the US version is the original.

What a pity we don't have video of the ancient Romans - I wonder if there were differences in pronunciation in the ancient world. Regional accents, did no one write about them.

In fact the contents of the 1963 book are just as visible as those of the older book, see:

Chlidanthus appears on page 71 of the book.
