artificial pollination

[Eric Wollenshaeger]

Hi Gorgio,

My experience with artificial pollination is poor.

I use a very simple method and results are very different from year to year
and depending on species.

I collect the pollen once ripened when it fall down in the spate, whit a
small brush.

I immediately pollinate the female flowers, with the same brush I've use to
collect the pollen.

If I've pollen available I pollinate the first time immediately after the
female flowers open.

I repeat the same 2 to 3 times in a week to have a maximum chance to obtain
seeds. I don't know when the ovaries are ripened.

I've never try to store the pollen.



Hope this helps

Eric
