Development of Seeded and Seedless Avocado Fruits1

Abstract

Abstract The seed influences rate of growth, size, shape and maturation of avocado fruits. Seeded fruits are 8-10 times larger than seedless ones and contain more and larger cells. The growth pattern of seeded and seedless fruits is similar from June until maturation, when growth rate of seeded fruits decreases. Fruit maturation is characterized by rapid accumulation of oil in the mesocarp, preceded by shriveling of the seed coats, and the discontinuation of the seeds’ influence on fruit growth. The role of the seed in the development of avocado fruit is discussed.
