Abstract


The paper presents the results of the study on seed morphology of eight following Allium species: A. pyrenaicum Costa & Vayr., A. rotundum L., A. sphaerocephalon L., A. vineale L., A. moly L., A. karataviense Regel, A. fistulosum L. and A. nutans L. The study confirmed the substantial diversity in testa characters, especially curvature and relief of anticlinal walls as well as microsculpture of outer periclinal walls. The occurrence of raised anticlinal walls - an unusually rare feature in Allium seeds, previously observed only in a few species, was found in A. karataviense. It was also found that the testa type in A. pyrenaicum did not match the typical character combination, described before for subg. Allium sect. Allium.
