Arabinogalactan A from Japanese larch (Larix leptolepis)
Journal of the Chemical Society C: Organic, 1968Fractionation of the water-soluble polysaccharides from Japanese larch wood affords two homogeneous arabinogalactans A and B. Mild acid hydrolysis of arabinogalactan A furnishes 3-O-β-L-arabinopyranosyl-L-arabinose. Hydrolysis of methylated arabinogalactan A gives 2,3,4- and 2,3,5-tri-, and 2,5-di-O-methyl-L-arabinose, 2,3,4,6-tetra-, 2,3,4- and 2,4,6 ...

Vertical seed dispersal, involving seed movement to higher or lower elevations, plays a vital role in plant adaptation to rising temperatures. However, its assessment has been limited owing to labor‐intensive processes.

Application of Hierarchical MFI Zeolite for the Catalytic Pyrolysis of Japanese Larch
Journal of Nanoscience and Nanotechnology, 2010The catalytic pyrolysis of Japanese larch was carried out over a hierarchical MFI zeolite (Meso MFI C16). The zeolite was synthesized using an amphiphilic organosilane as a mesopore-directing agent, and its catalytic activity was compared with that of the conventional HZSM-5 and the mesoporous material from HZSM-5 (MMZ(ZSM-5)).

Meria laricis on Japanese and hybrid larch in Britain
Transactions of the British Mycological Society, 1956The occurrence of Meria laricis Vuill. on Japanese larch (Larix leptolepis) and Hybrid larch (L. Eurolepis) in 1954 is recorded. These are believed to be the first British records on these hosts though the parasite has been recorded frequently causing Leaf Cast of European larch (L. decidua) in Britain.

Chesapeake Science, 1970
Studies on the feeding habits of larch sawfly larvae,Pristiphora erichsonii (Hartig), in Maryland, substantiated previous reports of a feeding preference for spur foliage over elongated shoot foliage. In field examinations on 20 infested Japanese larch trees, significantly greater quantities of foliage were consumed from spurs than from elongated ...

Growth-curve differentiation among Japanese larch provenances
Canadian Journal of Forest Research, 1991Height–age regression models were fitted to observed heights at ages 7, 11, 15, 22, and 29 years in 20 Japanese larch (Larixleptolepis (Sieb. & Zucc.) Gord.) provenances. A generalized least squares approach with maximum-likelihood estimation of the autocorrelation function and the variance function (heteroscedasticity) is proposed as a framework ...

Hydrothermolysis of Flavonoids in Relation to Steaming of Japanese Larch Wood
Holzforschung, 2002Summary Four flavonoid compounds, ((+)-taxifolin, (+)-aromadendrin, quercetin and (−)-naringenin), from Japanese larch (Larix leptolepis) wood were heated at 170 ℃C for 60 min at pH=3.46 (hydrothermolysis treatment). Alphitonin, four taxifolin steric isomers and quercetin were recovered from the treatment of (+)-taxifolin, and maesopsin ...

Minor compounds of the oleoroesin of the Kamchatka, Japanese, and Siberian larches
Chemistry of Natural Compounds, 1986The polyfunctional compounds of the oleoresins of three species of larch have been studied. Larixol diacetate, 3β-hydroxyepimanool, and 15-oxopimara-4(14)-enoic 13-hydroxy-7-oxoabicta-8(14)-enoic, 3β-hydroxysandaracopimaric, and 8,15-dihydroxyabietic acids have been isolated for the first time.
