Dear All,

As promised before I would like to update you with my experiments using microwaved pollen on self incompatible plants.
In this case Hippeastrum evansiae. This plant has been flowering for me for more than 20 years and never set seed. It is a stoloniferous bulb, so a big potful is just one clone. (Clone 1)  This year I had a different clone (Clone 2) in flower for the very first time. So comparison is possible between cross pollination and self pollination.
The result is very simple:
All flowers pollinated with microwaved pollen did not set seed, almost all cross pollinated flowers have big seed capsules in both directions and all flowers left unpollinated aborted as well.
Here is the number of flowers in detail 
Clone 1: 9 scapes with 20 flowers. Of which 4 flowers were left with no pollination 
9 flowers were repeatedly pollinated with microwaved pollen following the procedure described here https://pacificbulbsociety.org/pbswiki/index.php/…
7 flowers were pollinated using pollen of clone 2 of which one aborted, why?
Clone 2: one scape with 2 flowers. Both flowers were pollinated with pollen of clone 1 and have big seed capsules.
Last year I successfully produced one seed pod on clone 1 with its own microwaved pollen but I have no record of the exact details of the procedure, it was not exactly the same as used this year. So…. Many open questions…..

Then there is an unnamed Albuca species (it is not Albuca aurea which sets copious amounts of seed) of which seedlings produced of microwaved pollen are flowering for the very first time. Unfortunately the mother plant is very delayed and in declining condition so that a direct comparison is not possible at this moment. From memory they are identical to the mother. The seedlings appear uniform and very healthy, there are more than these three ones.

The seedlings of Albuca clanwilliamigloria are still growing well but will soon go dormant.

The pictures show the flowering plants of Hippeastrum evansiae  (not a brilliant foto) the flowers in the left upper part are clone 1 and the two flowers on  the lower right side are clone 2. they are slightly different with clone 2 having slightly wavy petals and a green throat 

The second picture shows maturing seed capsules. They are big but the camera has oversized them. Not all of them are in the pictures, the 3 capsules on the left are clone 1 and the two on the right are clone 2

The third picture shows the Albuca species, flowering  seedlings.
