Bicyclic diterpene acids from the oleoresin of Pinus sibirica

Chemistry of Natural Compounds, 1972
The acid fraction of the oleoresin ofPinus sibirica R. Mayr. contains pinusolic acid (labda-8(20), 13-dien-16,15-olid-19-oic acid), and isocupressic and trans-sciadopic acids. The hydroxy acids were isolated and identified in the form of the methyl esters.

Embryo initiation from Pinus sibirica megagametophytes in in vitro culture

Russian Journal of Developmental Biology, 2014
Megagametophytes of Siberian pine were cultured on an in vitro culture medium 1/2 LV supplemented with growth regulators 2,4-dichlorophenoxyacetic acid (2,4-D) and benzylaminopurine (6-BAP) to form embryos. The competency of somatic cell of explants to embryogenesis manifested itself in an organized growth and polarity.

Structure of a New Diterpene Alcohol from Pinus sibirica Buds

Chemistry of Natural Compounds, 2005
The newditerpene alcohol (1) in addition to the known metabolitesisoagatholal (2) and β-sitosterol glucoside (as the tetraacetate) (3) were isolated from buds of Siberian pine. The structure of the new compound was established as abieto-8(14)-en-18-ol 9α,13α-endoperoxide.

Structure and CO2 Exchange in the Needles of Pinus sylvestris and Abies sibirica

Russian Journal of Plant Physiology, 2001
The morphological and functional organization of the needles of Scotch pine (Pinus sylvestris L.) and Siberian fir (Abies sibirica Ledeb.), which differ in their light requirement were studied. The characteristic properties of the high-light-requiring pine included high rates of apparent photosynthesis and dark respiration, high assimilation number ...
