Microscopy of Fennel Fruit

Microscopy of fennel fruit shows that the transverse section contains five vascular strands in the five ridges, with a small secretory canal in each rib and six vittae. The epidermis of the pericarp is composed of polygonal cells and contains occasional stomata. The mesocarp is mostly polyhedral parenchyma with cellulosic walls, but also contains thickened and lignified parenchyma near the vascular strands. The vittae are very long, extending from the base to the apex of the fruit and tapering at the ends.
