Fruit set is the process by which flowers develop into fruits after fertilization. This occurs when pollen from the male part of a flower reaches the female part, leading to the formation of seeds. Successful fruit set is crucial for plant reproduction and can be influenced by factors such as temperature, humidity, and pollinator activity. During fruit set, the ovary of the flower begins to swell and mature, eventually transforming into a fruit that contains seeds. Different plants have varying fruit set mechanisms, with some relying on pollinators like bees, while others may self-pollinate. Understanding fruit set is essential for agriculture and horticulture.
