P. lutea grown from seed /different looking plants

[Brian Barnes]

Hi,
Hey...I see that too! The corolla definitely looks glandular in places. Interesting....
Brian.

Daniel..fantastic...

Hi Agota, Brian and Jeff,

thanks for the kind words.

The flower stalk is getting longer and longer, it´s now about 25cm high and i have had to remove the plant to another place because it was reaching the lights.
I hope it will not get much longer.

Brian, a cross with D. filiformis would be really great. ;D ;D ;D
Interesting that you don´t have these tentacles under the leafes, from my plants only 2 have these tentacles. I will continue to check the leafes from all plants to see if only these 2 plants will continue to produce these tentacles.

Jeff and Brian, yes, the corolla is definitely looking glandular, with my eyes it´s almost not visible (and i don´t have a problem with my eyes ), but on the pictures it´s very clear.

Jeff, here are 2 pictures from the sepals from behind.




Best regards,

Dani

excellent, many thanks

Hi all ,

do this species need to be cross pollinated with another plant/flower or is one flower enough?
I´m asking this because of this link:
www.pinguicula.org/A_world_of_Pinguicula_2/Pages/pinguicula_lutea.htm
There is written that some plants are forming seed in culture, but obviously some not, is it right?

And what is with P. planifolia, primuliflora, caerulea, ionantha and pumila, do they need to be cross pollinated or is one flower enough?

Last year i was not successful with the pollination of the 2 plants without location (they have not flowered at the same time), i´ve tried it but nothing happened.

Best regards,

Dani

it is always preferable to make a genetic mixing with 2 flowers of 2 different plant from one area or an others.

it is rather difficult to reach on these species the stigmate and the etamine this sort of feather duster often is an inconvenience

[Brian Barnes]

Hi Dani,
Oddly enough, I have self-pollinated all of the American Pinguicula species except for P. primuliflora. For some reason it is not receptive to self-pollination in my conditions...
However, cross -pollination between two different plants produce a larger amount of seed and the viability/germination rate drastically increases.
With Pinguicula, I usually split the tops of the flowers with a sharp razor blade to expose the anthers and stigma. Then, working with the flowers is quite easily done and the flower is not completely destroyed. I prefer to work with colored toothpicks to make sure visibly, that pollen is obtained.

Also, keep in mind that everyone's specific growing conditions such as temperature, humidity, etc....does have a distinct effect on pollen production/viability and stigma receptability. This applies to all CP species as well, in my experiences.

Happy Growing,
Brian

Hi my friends,

thanks for the explanation.

Brian, interesting that you have not managed to self pollinate P. primuliflora, but it´s good to hear that theoretically it should be possible to self pollinate the others.
For sure it has something to do with the conditions we are giving them in culture.
But you are right, for sure it´s also better to cross pollinate them to have a bigger genetic pool, but in the moment only this one plant is flowering.

So, the best way to pollinate them is to destroy the flower partially like it is described here:
www.pinguicula.org/A_world_of_Pinguicula_2/Pages/Pollenisation_Pinguicula.htm
I don´t wanted to believe it but if it´s also your experiance it must be the truth.

3 days ago (after the flower was opened for 4-5 days) i "tried" to pollinate it without "destroying" the flower (till now i have never been successful with pollinating Pinguicula flowers, but i tried it only 3 times), with a toothpick of course ;D, and i really managed to take some pollen (it was really hard ) and i have transfered it on the stigma, i hope so.

And a few minutes ago when i checked the plant again i saw that the complete flower has fallen down (much faster than without the try to pollinate it) but without drying out before.
Is it a good sign or not?

Best regards,

Dani

Hi Dani,
Sounds like you may have successfully pollinated it! You should see the capsule beginning to swell immediately, within a few days if you were successful.
Happy Growing,
Brian.

[jeff]

no the problem with the temperate ping they are fertilized all alone ;D

[Brian Barnes]

Hi Jeff,
I've heard some growers say that some Mexican Pinguicula will self pollinate by itself without any assistance. Have you found this to be true?
Happy Growing,
Brian.

[daniel]

Hi Brian and Jeff,

i agree that most/all of the temperate species are self pollinating without any assistence but till now i have never heard that some Mexican species are self pollinating in culture without any assistence too.
Perhaps it´s possible if the pollinators are the right ones, but i have heard from nobody here in Europe that they are self pollinating without any assistence and i have never had self pollination with my about 20 species i´m growing here.

From my own experiance it works perfect with P. sharpii , an annual from Mexico, perhaps it also works with other annual mexican species like P. lilacina,....
From an other CP grower (Markus W.) i have heard that the very rare P. crenatiloba is also self pollinating without any assistence.

Bye the way, i think that the seed capsule is really swelling.

Best regards,

Dani

bonjour BRIAN and DANIEL

I have some self pollinating on anpa and sometimes on some common hybrids ;D

[Brian Barnes]

Hi Dani and Jeff,
Excellent Dani, it sounds like you'll have lots of seed soon! and also soon, you'll have a tray full of P. lutea! ;D

Jeff,
To your knowledge, has a hybrid between P. macrophylla X P. AnPa D been created yet? I have three plants from a successful cross I made, that should be flowering very soon. One even has the wide leaves of P. macrophylla and the purplish tint to the edges of the leaves like P. AnPa D! All three plants are showing hybrid vigor too...

Happy Growing,
Brian.

[jeff]

although I am not hardly interested in the hybrids(except for the naturals), can be will be able you to show to us a photograph when it is in flower.
