2021
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.

Phenylpropanoids in mycorrhizas of the Pinaceae

Planta, 1999
Tissue-specific accumulation of phenylpropanoids was studied in mycorrhizas of the conifers, silver fir (Abies alba Mill.), Norway spruce [Picea abies (L.) Karst.], white pine (Pinus strobus L.), Scots pine (Pinus silvestris L.), and Douglas fir [Pseudotsuga menziesii (Mirbel) Franco], using high-performance liquid chromatography and histochemical ...

BIOGENIC SILICA IN THE PINACEAE

Soil Science, 1978
ABSTRACT 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 ...

Early evolution in the Pinaceae

Review of Palaeobotany and Palynology, 1976
Abstract Nineteen species of structurally preserved ovulate cones of the Pinaceae are known from the Cretaceous. One of these belongs to Pinus , while the others contain anatomical features necessitating their classification in the organ genera Pityostrobus and Pseudoaraucaria .

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.

Identification of COS markers in the Pinaceae

Tree Genetics & Genomes, 2008
Conserved ortholog set (COS) markers are evolutionary conserved, single-copy genes, identified from large databases of express sequence tags (ESTs). They are of particular use for constructing syntenic genetic maps among species. In this study, we identified a set of 1,813 putative single-copy COS markers between spruce and loblolly pine, then designed

The hydraulic architecture of Pinaceae – a review

Plant Ecology, 2004
We reviewed the literature to examine the vulnerability to water stress-induced embolism of Pinaceae relative to other conifers and to study the inter-relationships among the main traits involved in the hydraulic function within the Pinaceae. Results showed that Pinaceae (particularly the genus Pinus) are more vulnerable to xylem embolism, and show ...
