Phal. seeds without embryos

[Luiz]

Dear all,

I attempted some crosses between large white Phalaenopsis and between large pink Phalaenopsis (unfortunatelly I don't know the exact varieties I was crossing).

The resulting seeds (90 to 100%) are mainly without embryos as seen under the microscope.

I collected 5 seed pods from each mother plant, and so I wonder if the high seed sterility was due to genetics or to the energy depletion caused by too many pods on one plant.

Could anybody comment on that?

Thank you very much!
