Growth of Pinus pumila and climate fluctuation in Japan

Nature, 1977
TREE-RING analysis shows a relationship between annual ring growth and climatic changes in the United States1–3 and in the Scandinavian countries4. We have measured annual growth in terms of elongation of the terminal shoot of dwarf pine, Pinus pumila (Pallas) Regel, which is common in the alpine zone of Japan and eastern Siberia. This tree was used as

A New Triterpene Glycoside from Pinus pumila

Chemistry of Natural Compounds, 2021
In the current work, a novel triterpene saponin, named ursolic acid 3-O-[α-L-rhamnopyranosyl(1"→6')]-β-D-glucopyranosyl-28-O-β-D-glucuronopyranoside (1), together with two known flavonol glycosides, kaemferol 3-O-α-L-rhamnopyranoside (2) and quercetin 3-O-β-D-glucopyranoside (3), was isolated from the stem outer barks of Pinus pumila by repeated column

Terpenoids of the oleoresin of Pinus pumila

Chemistry of Natural Compounds, 1976
1. The composition of the acid fraction of the oleresin ofPinus pumila (Pall.) Regel. has been studied, and from it has been isolated, in addition to known compounds, the methyl ester of a new labdane acetoxy acid. 2. In the hydrocarbon fraction of the oleoresin 11 monoterpenes and 26 sesquiterpenes have been found (and 17 of the latter have been ...

Climatic controls of Pinus pumila radial growth along an altitude gradient

New Forests, 2021
Recent temperature rise caused by human activities has led to profound changes in the forest ecosystem. Shrubs play an important role in the boreal forest. However, it is not clear how shrub growth responds to climate change, especially whether there is a difference in the response of shrub at different altitudes to climate change.

Comparative sequence analysis of the LEA gene fragment in Pinus sibirica Du tour and Pinus pumila (Pallas) Regel

Russian Journal of Genetics, 2014
A comparative sequence analysis of the LEA (Late Embryogenesis Abundant (LEA)-like gene) intron fragment was performed in Pinus sibirica and P. pumila differing in geographic origin. It was demonstrated that in P. sibirica this fragment was represented by two types of PCR products, 224 and 202 bp in size. Similarly, in accessions of P.

Extensive Mitochondrial Introgression from Pinus pumila to P. parviflora var. pentaphylla (Pinaceae)

Journal of Plant Research, 1999
species exhibit a paternal chloroplast inheritance and a maternal mitochondrial inheritance. The levels and patterns of cpDNA and mtDNA introgression between the two pine species, P. pumila and P. parviflora var. pentaphylla, were examined at three mountain sites in Japan.
