Seed Pod development
The best way to explain my question is to give an example.
Take a female N. ventricosa flower.
Pollinate the bottom half of the flower with (for example) N. gracilis and the top half with say N. khasiana.
Once the flower is finished and the ovary/seed pods are starting to swell, what would it mean if the pods from the top half of the flower were actually becoming bigger than the bottom half (even though they were later to develop and be pollinated).
My first thought is the possibility that the N. gracilis pollen was not viable and these flowers were not fertilised.
However, could it also be that N. gracilis develops smaller sees than N. khasiana and this is being reflected in the size of the developing seedpods?
Note: donít take the literal size difference between gracilis and khasiana seed into account if it is a factor. These are just for the example.
