Labdane Diterpenoids and Shikimic Acid Derivatives fromAraucaria cunninghamii
Planta Medica, 2010Four new (1-4) and two known compounds (5, 6) were isolated from the aerial parts of Araucaria cunninghamii. By analysis of UV, IR, MS, and NMR, the new compounds were identified as ENT-19-(Z)-coumaroyloxylabda-8(17),13(16),14-triene (1), ENT-19-( E)-coumaroyloxylabda-8(17),13(16),14-triene (2), shikimic acid N-butyl ester (3), and 5-(Z ...

Nitrogen in the Growth of Araucaria Cunninghamii Ait. Underplanted in Pinus Stands
Ecology, 1970Hoop pine (Araucaria cunninghamii Ait.), a nitrogen—sensitive rain—forest species can be grown without fertilizers as an underplanting to established stands of Pinus, on soils which will not support open plantings of pure hoop pine without fertilizing with nitrogen at the rate of 112 kg/ha per year.

A matrix population model analysis for the tropical tree, Araucaria cunninghamii
Austral Ecology, 1991 The temporal stability of estimates of demographic behaviour for a sample population of the tropical rainforest gymnosperm Araucaria cunninghamii was analysed using a stage-classified (Lefkovitch) matrix model.

Zinc uptake by mycorrhizal and uninfected roots of Pinus radiata and Araucaria cunninghamii
Soil Biology and Biochemistry, 1974Abstract Uptake of zinc from solution by uninfected roots, ectomycorrhizas of Pinus radiata, and endomycorrhizas of Araucaria cunninyhamii occurred by a non-metabolic phase and by metabolically mediated absorption. The metabolically mediated absorption of Zn was 1.4–4.5 times greater for ectomycorrhizas than for uninfected roots and 2.6 times greater

Analysis of the Leaf Oil ofAraucaria cunninghamiiSweet. Grown In Nigeria
Journal of Essential Oil Research, 2005The yield and chemical composition of the oil obtained by hydrodistillation of the leaves of Araucaria cunninghamii Sweet., grown in the southwest region of Nigeria are reported. The analyses were made by GC and GC/MS. The oil was found to contain α-pinene (14.8%), terpinen-4-ol (14.7%), shyobunol (8.9%) and spathulenol (8.8%) as major constituents.

Environmental and biological control of flowering in hoop pine (Araucaria cunninghamii Ait.ex.D.Don)
2023The availability of high genetic quality seed from hoop pine seed orchards has been the major factor in the successful plantation program with hoop pine (Araucaria cunninghamii Ait. ex. D. Don) in Queensland, Australia. However, delays in the onset of flowering and large annual variations in the production of strobili (particularly male strobili) have ...

Characterization of Hoop Pine (Araucaria Cunninghamii Sweet) for Ply and Particleboard Manufacture
Indian Journal of Forestry, 2014Studies for assessing the suitability of Hoop-pine (Araucaria cunninghamii) wood for plywood and particleboard manufacture. It was found that 1.5 mm thick smooth and figured veneer can be made and dried easily. Three-ply plywood were made using veneer of this species bonded with liquid urea formaldehyde glue of 50% solid content, extended with wheat ...

Climatic effects on the diameter growth of Araucaria cunninghamii Ait. ex D. Don.
Forest Ecology and Management, 1985Abstract Monthly diameter increment data from two Hoop pine sites in Queensland were related to variables derived directly from weather measurements or from calculations made with a growth model including a simple water balance simulation. Both sets of variables were analyzed using stepwise multiple regression, along with variables representing ...
