摘要

The structure of mucilage containing cells in the achene pericarp of some Artemisia species was studied with a transmission electron microscope. Several types of the mucilage containing cells are found in the exocarp. The most essential differencesare revealed in the cell contents. Some contain silica compounds in the mucilage, others contain cellulose lamellae often arranged in piles. On transverse and longitudinal sections the mucilage containing cells differ from the main exocarp cells by swollen electron-transparent outer cell walls with no silica compounds. The cells with cellulose lamellae are arranged in complexes. Such complexes in different Artemisia species contain the species-specific number of such cells encased by a common mother cell wall. "Mucilisation" or "non-mucilisation" of the outer cell walls is found to be caused by 3 factors: (1) lack of a hardening substance (silica), (2) absence or presence of cuticle on the outer cell walls and (3) a character of the cell contents.
