What are infructescences, pseudofruits and parthenocarpic fruits?
Infructescences are aggregated fruits created from inflorescences, aggregated flowers. Grape clusters are instance of infructescences. Pseudofruits are "fruits" not made in the ovaries and in general their true fruits lack development and are found within the flesh, like in apples and pears. Parthenocarpic fruits are those made without fecundation, by means of hormonal stimuli, like bananas.
