Abstract

We present in the article data on some samples of seeds of plant species from the family Apiaceae or Umbelliferae, which were obtained by the Botanical Garden of UNN, a total of 53 samples of 18 species: Astrantia biebersteinii, A. major, A. maxima, Azorella trifurcata, Bupleurum aureum, B. longifolium, B. rotundifolium, Eryngium agavifolium, E. alpinum, E. ametystinum, E. giganteum, E. maritimum, Laser trilobum, Myrrhis odorata, Peucedanum oreoselinum, Prangos trifida, Sanicula europaea and Seseli annuum. To compare samples, the weight of 1000 seeds was used. The length and width of the mericarps were measured, and the ratio of width to length was determined. New data are available on the linear dimensions of the mericarps of Eryngium agavifolium and Astrantia trifurcata, and in the latter also on the weight of the seeds. In the genus Eryngium, most species have a large scatter in the average linear dimensions and weight of mericarps, both in the studied specimens and in other publications. In some cases, in the genus Eryngium, samples with the largest seeds turned out to be non-germinating, while those with small ones were germinating. In the genera Astrantia, Bupleurum, Eryngium and Laser, the seeds of the specimens that have the greatest weight do not always have the largest average size, and the smallest are not always the lightest. In the genera Peucedanum, Prangos, Sanicula, Seseli, the weight of seeds is proportional to their average linear size. Despite the small number of samples of some species or seeds in them, the data obtained can be used to compare seed material of different origins and decide on additional study of questionable samples. Deviations in seed parameters may be associated with morphological variability or result from the influence of growing conditions of mother plants.
