Study Notes
Learning Outcomes
- Students will be able to describe the process of fruit formation and maturation.
- Students will be able to compare diverse fruit structures and types.
What is a Fruit?
- Botanically, a fruit is one or more ovaries, along with associated tissues, that have matured and ripened.
- Horticulturally, a fruit is one or more mature ovaries plus accessory tissues; possessing high sugar content and typically eaten as dessert, in salads, or snacks.
Fruit Structure and Development
- Fruits develop as a result of pollination and/or fertilization.
- Fruit is an accessory reproductive structure in flowering plants (angiosperms).
- It contains seeds.
Fruit Classification
- Simple Fruit: Develops from a single pistil (e.g., pea, tomato, apple, cucumber).
- Aggregate Fruit: Develops from multiple, separate carpels of a single flower (e.g., strawberry, raspberry).
- Multiple Fruit: Develops from multiple carpels of multiple flowers within an inflorescence (e.g., pineapple, fig).
- Accessory Fruit: Develops from tissues other than the ovary (e.g., apple, pear).
Factors Influencing Fruit Structure
- Flower structure influences fruit structure.
- Ovary position, number of ovaries.
Fruit Maturation
- Fruit maturation is typically characterized by changes in color, texture, flavor, and aroma. These changes are due to increases in the production of volatile compounds, associated with fruit ripening.
- This occurs as the fruit ripens and the starch is converted to sugar.
