Human endeavors in both commercial and residential strawberry growing operations account for a significant degree to which strawberry seeds are dispersed. Total mean seed production of trees in the smaller size class was one-half of that of the large trees. Seeds in a linear order, separate from ovary wall, pericarp splits on two seams Legume (immature), 4. This chapter section will cover the anatomy of a fruit, including the ovary, different fruit types, and finally, how these fruits are specialized for different dispersal mechanisms. 463) completely cover cotton seeds.
