metadata.value: As a result of analysis of the quality of Pinus pumila seeds by the method of
  microfocus X-ray radiography in combination with the automatic analysis of
  digital X-ray images, it was found that the best characteristics of individual
  structures and organs of seeds were demonstrated in samples collected from
  trees growing at site 71 of BIN RAS; the worst — from seeds taken from South
  Sakhalin. The seeding qualities of Pinus pumila seed samples were determined
  by standard methods. Based on analysis of the characteristics of digital Xray
  images of Pinus pumila seeds, it was found that a seed sample from site
  71 BIN RAS was characterized by the high level of embryo area 4.19 ± 0.49 mm2,
  maximum embryo to thalus ratio 60.95 ± 7.45 %, high level of endosperm area
  23.93 ± 1.24 mm2, and maximum ratio square of embryo area 9.45 ± 1.17 %.
  The same sample was characterized by a maximum weight of 1000 seeds and
  a maximum absolute and soil germination ratio, compared to other samples.
  The obtained data showed that Pinus pumila seeds collected from plants introduced
  in northwestern Russia by most parameters are not inferior or are even
  superior to seeds from the natural range.
