Heterozygosity level was analyzed in the plant samplings with maximum and minimum full-grained seed productivity of five native Pinaceae Lindl. species. It was found out that the trees with maximum full-grained seed productivity were characterized by an average populational level of heterozygosity for Pinus sylvestris L., P. pallasiana D.

Karyological differentiation of bog and dry valley populations of Pinaceae is due to differences of microevolutional process in forest stands in contrast environmental condition of bogs and dry valleys. Diploid chromosomal sets of dry valley populations of Pinaceae species are equal to 2n = 2x = 24.

Chemical Composition of Pinus sibirica (Pinaceae)
Chemistry & Biodiversity, 2015AbstractSiberian pine (Pinus sibirica), also known as Siberian cedar pine and Siberian cedar, is an important plant that has been long used as a source of natural compounds and materials (wood, needles, soft resin, turpentine, colophony). Its chemical composition has been studied well enough; however, to our surprise, no articles that compile the ...

ANATOMICAL STUDIES OF CATHAYA (PINACEAE)
American Journal of Botany, 1984Cathaya Chun et Kuang is a monotypic genus and one of the gymnosperms endemic to China. We investigated Cathaya argyrophylla with both light and scanning electron microscopy to study the external and internal surfaces of leaf cuticle, leaf blade, petiole, shoot apex, young stem, bark, wood, young and old roots, and mycorrhizae. It is shown that Cathaya

BIOGENIC SILICA IN THE PINACEAE
Soil Science, 1978ABSTRACT Biogenic opal was isolated in measurable quantities from 15 taxa of the family Pinaceae. Opal contents varied from 0.08 percent of dry weight in Pinus resinosa to 1.37 percent in Larix decidua. The silica content of a widely ranging species, Tsuga canadensis, varied significantly with collection location in New York State, but the causes of ...
