Monoterpenes from three different members of the Anthemideae family, Artemisia tridentata ssp. vaseyana, Artemisia cana ssp. viscidula and Artemisia tridentata ssp. spiciformis were isolated and their structures determined using spectroscopic techniques. A total of 26 irregular and regular monoterpenes were identified.

Pollen dispersal by Artemisia tridentata (Asteraceae)
International Journal of Biometeorology, 2007While the biophysics of anemophilous pollen dispersal is understood in principle, empirical studies for testing such principles are rare, particularly in native ecosystems. This paper describes mechanisms underlying the dispersal of Artemisia pollen in a Wyoming sagebrush steppe.

Root Growth of Artemisia tridentata
Journal of Range Management, 1988We designed a greenhouse study to test the following 2 hypotheses: (1) root growth of Wyoming big sagebrush (Artenhia tridentata ssp. wyomingensis) exceeds that of basin big sagebrush (A.t. ssp. tridmtata) and mountain big sagebrush (A.1. ssp. vaseyana) during the first 10 to 40 days after planting, and (2) root length of basin big sagebrush exceeds ...

Sesquiterpene lactones of Artemisia arbuscula and A. tridentata
Phytochemistry, 1973Abstract Chloroform extracts of Artemisia tridentata ssp. vaseyana f. spiciformis (Osterhout) Beetle and Artemisia arbuscula Nutt. ssp. arbuscula gave identical TLC patterns and contained the known germacranolides tatridin-A (I) and tatridin-B (II), and two new germacranolides deacetyllaurenobiolide (III) and spiciformin (IV).

THE CHROMATOGRAPHIC CHARACTERIZATION OF ARTEMISIA, SECTION TRIDENTATAE
American Journal of Botany, 1965Acid methanol leaf extracts of all of the eleven species assigned to the Section Tridentalae of Artemisia by Beetle were chromatographed using a descending two‐dimensional method.

Nevada State Undergraduate Research Journal, 2014
Big sagebrush (Artemisia tridentata) and antelope bitterbrush (Purshia tridentata) are native species to the sagebrush ecosystem of northern Nevada. Both of these species exhibit allelopathic effects, whereby they produce chemicals that inhibit or prevent the growth of other plants nearby.

On the structure of a novel ether from Artemisia tridentata
Phytochemistry, 1979Abstract 1,6,6-Trimethyl-4-ethenyl-2-oxabicyclo-[3. 1.0]hexane was unambiguously synthesized in seven steps from 4,5-dihydro-2-methylfuran. The product possessed IR, 1 H NMR and MS which differed from those of a compound isolated from Artemisia tridentata .

Current methods for determining plant age of shrub species require destructive sampling and annual growth ring analysis on the primary stem. Although individual plant ages can frequently be determined in this manner, the method is time consuming and of ...

Investigation of Artemisia tridentata as a biogeochemical uranium indicator
Journal of Geochemical Exploration, 1985Abstract Hydroponic experiments were conducted with seedlings of Artemisia tridentata subsp. tridentata (big sagebrush) to test the effect of the phosphate speciation of uranium in solution on its uptake by big sagebrush. No single complex could be identified as being preferentially taken up by the plant, but the varying aqueous phosphate ...

SEASONAL PATTERN OF NET PHOTOSYNTHESIS OF ARTEMISIA TRIDENTATA
American Journal of Botany, 1973Gas exchange studies were carried out on Artemisia tridentata during the course of a growing season using microclimatically controlled cuvettes and infrared gas analysis. A definite seasonal pattern of net photosynthesis emerged.
