The mesocarp of the fruit becomes thin during maturation because of dual purpose: it is drying out, and has been pressed by the great mass of endospermium. The areas of vallecular oil ducts also decrease. The carpophore splits at maturation as a result of an abscission zone. This zone is a lignified tissue between the two ventral veins (Figure 22). V.

The changes in main mono- and disaccharides content during caraway two years vegetation period is described in details by Hopf and Kandler (1976). Other disaccharides found in the seeds in minor amounts are: trehalose, glucosyl mannose and mannityl-1-β-glucose. The most interesting trisaccharide of Carum is perhaps umbelliferose (Figure 1a), an isoraffinose typical to umbellifers, found in all parts of the plant and serving as a temporary reserve material similar to sucrose. It occurs in greater amounts than sucrose only in the ripe fruits and is not preferentially accumulated in any particular vegetative organ.
The cytokinesis of the pollen mother cells is simultaneous type. The thick callose wall intrudes centripetally and separates the four microspores only after the second division of the pollen mother cells. Pollen tetrads are tetrahedral, decussate or isobilateral. The tricolporate pollen grains have bilateral symmerty (Figure 9). At the time of shedding they are at three-celled state. The gynoecium fused of two carpels. The upper part of the ovary is surrounded by a nectary (discus). On the surface there are numerous nectar stomata sunken below the epidermis with special ornamentation on its cuticle (Figure 10).
