Nutation in Pinus Sylvestris

Botanical Gazette, 1928
1. A long series of observations on the elongating shoots of Pinus sylvestris showed that during the elongating period the new shoots are subject to nutations, which are caused by differentiation of the water pressure on the different sides, resulting in growth curves in the direction where the turgidity was least.

Polyisoprenols in Pinus sylvestris needles

Phytochemistry, 1974
Abstract A polyisoprenoid fraction was isolated from the needles of Pinus sylvestris and comprised about 1% of the dry weight. MS, IR, GLC and HPLC analyses showed that the fraction consisted of polyisoprenylacetates, with 10–19 isoprene units predominantly in the cis configuration.

The Water Relations of Pinus sylvestris

Physiologia Plantarum, 1977
AbstractThe water potential (β) in ten‐year‐old Scots pine trees (Pinus sylvestris L.) from four different latitudinal provenances ranging from 57° N to 67° N, growing in close proximity to each other, was measured in a pressure chamber during five selected periods between May 1972 and March 1973.

Chemistry of Pinus sylvestris cones

Chemistry of Natural Compounds, 2006
The chemical composition of the individual organs (needles, needleless runners, buds, cones) of common pine (Pinus sylvestris L.) was studied in order to develop and improve industrial reprocessing of green wood. Second-year cones have not been studied previously. We attempted to find the dominant components of the extract.

2014
In Pinus sylvestris L. populations exposed to the impact of a chemical enterprise, variation of a seminification index (the number of full-grained seeds in a cone) has been studied. The greatest number of full-grained seeds in one cone and their variation are observed in a zone of acute impacts of emissions.

Micropropagation of Pinus sylvestris

1993
Pinus sylvestris is one of the most widespread conifers in Europe and Asia. Its geographic boundaries lie between 70°20′ northern latitude in Scandinavia and 38°41′ south in Central Turkey, and the species survives at altitudes of up to 2000m [52]. It is a very variable species that grows on different types of soils.

Specific Cytogenetic Characteristics of Pinus cretaceae and Pinus sylvestris

Russian Journal of Ecology, 2004
A comparative cytogenetic study has been performed in four populations of two pine species, Pinus cretaceae Kalen. and P. sylvestris L., growing on sandy and chalky substrates in Voronezh and Belgorod oblasts. Significant differences in the parameters of mitotic and nucleolar activities, as well as the rate and spectrum of mitotic pathology, between ...
