Cross-pollinate with stored pollen

On February 2nd 2017 I collected pollen from a Zamoano variety and stored this pollen in the refrigerator. Five days later I use this pollen on Hylocereus costaricensis to pollinate the flower.

I have 6 varieties. Is it a good idea to mix the pollens, use it, and then store it? Will it increase the chance of fertilization or do I keep them separate/use only one for all?

[@larrytatad6611]

My dragon fruit a lot of flowers , but there is pollen. The flower it's dry.I don't no what is the problem.

[@Spicyexotics]

I get that when temperatures are cool, usually in the 70s.

[@justicekeziah2157]

what will happen tonthe pollen if it isn't keep refrigerated overnight? does it still work or is it still usable?

[@Spicyexotics]

It will likely not work. Depending on your location, humidity prolongs the life of pollen, but only for a few hours.

[@unhappy_mousemaker8731]

About how long is the shelf life of stored pollen? And do you store them in the fridge or freezer?

[@Spicyexotics]

I store in the fridge and it lasts about 3 days. I have read others storing in the freezer can last months.

Thanks! :)

Do those lower starts flower too ?

[@Spicyexotics]

No, those are cuttings that have been removed from the top of the plant.

how wide is your greenhouse? 10ft or 7?

[@Spicyexotics]

12 feet

If i have only 1 variety for each pitaya (1 red 1 white 1 yellow) can i do this cross pollination? Could i do cross pollin from a flower of a plant to another plant flower?

[@Spicyexotics]

Yes, That is considered cross-pollination. It may not be successful. The only way to know is to try. Most Whites and Yellows are self-fertile, so no need to cross to set fruit.

[@MrKei96]

If i have 2 plant of red pitaya from the same fruit. Cross pollination of these two will work or i need another different red pitaya? Could i use white pitaya to pollinate a red one? Thanks.

[@Spicyexotics]

@@MrKei96 That's one of the major issues of growing a plant without knowing what named variety you have. Some red flesh varieties are self-fertile, some are Self Sterile or even Self-pollinating. The answer lies on identifying what your variety is capable of.
- Has it flowered? if so, did it set fruit?
- Do you know for sure you have a Red fleshed variety?
- If flower then no fruit, have you tried hand pollinating?
Knowing the above question can better answer your question.

[@MrKei96]

@@Spicyexotics I don't know the name of the red flesh or of the others, because i bought only the fruits. I'm trying to grow them so they are too young to produce flowers. I'm taking more informations as possible before that. I will try next.

Were could I buy the pollen
