Collecting Pollen
« Thread Started on Mar 14, 2008, 1:04pm »
Hej Guys

How do you collect pollen of Nepenthes?
And how do you store them?

Some use Aluminium foil and some use wax paper. What is the best?

Do you collect only the pollen or the pollen with anther?
Many Question but i hope that someone can give a answer.

Hi Jens,

I learnt to cut the anther and collect it as a whole, together with the pollen. It is then kept in a sachet made of brown paper with a waxy surface and dropped into a container of silica gel. I would leave them there until the pollen is to be given away or used. But if I want to store it for a longer period, I would keep them in the fridge after drying for 2-3 weeks.

Jens,

I suppose it can keep for several months to a year in a fridge. It depends on how well you dry the pollen. I used to think that pollen becomes non-viable very quickly and I gave them away soon after collection. But recently, I am beginning to store them for a longer period of time using the method I described.

Hej Cindy

Thank you so much to write you experiences here.
I think my dry method is very good. i have the pollen on a paper under lights in my TC setup. there is it dry and warm. So i think 2-3 days and i can ship them.

By the way. Does someone want N. talangensis pollen?
If someone is interessted send me a mail to: jens[@]nepenthes[.]se

I find it best to not save the anthers, but just the pollen grains by themselves. This prevents molding and the pollen actually stores better when collected dry without any tissue attached. Simply pinch the pollen anther with your fingers outside of a waxed paper enclosure. The pollen attaches itself to the waxed paper and is free from any mold spore contact. No fingers (with spores) and no tissues (with spores).
Fold the waxed paper and label what it is, and for long term storage, also note date.
I am hoping some day that pollen of species can be stored and when needed be available to make true pollinated species in captivity.
