What is the difference between pomology and olericulture?

Within the field of horticulture, both pomology and olericulture are specialized branches focused on the production of food crops, yet they differ in the types of plants they manage:

• Pomology is the science and practice dedicated to the cultivation of fruit and nut crops.123
• Olericulture focuses on the production, storage, processing, and marketing of herbaceous plants intended for the kitchen, commonly known as vegetables.143

While both disciplines fall under the broader umbrella of plant agriculture, they represent distinct areas of expertise for a horticulturist. Pomology centers on perennial fruit and nut-bearing plants, whereas olericulture encompasses a wide variety of vegetable crops, including those harvested for their roots, stems, leaves, or flower buds.3
