Explanation

Xenia in plants is the effect of pollen on seeds and fruit of the fertilised plant. The effect is different from the contribution of the pollen towards the next generation. The effect, such as an increase in size, on the embryo or endosperm of a plant results from fertilisation with pollen of a genetically distinct variety.
