DIFFERENCES IN DROUGHT ADAPTATION BETWEEN SUBSPECIES OF SAGEBRUSH (ARTEMISIA TRIDENTATA)

Ecology, 1999
Three subspecies of Artemisia tridentataoccupy distinct habitats in the Great Basin of North America: ssp. wyomingensis in low, arid elevations; ssp. vaseyana in high, mesic elevations; and ssp. tridentata in intermediate zones. We evaluated differences in the drought experienced and drought tolerance among the subspecies.

The monoterpenes of Artemisia tridentata ssp. vaseyana, Artemisia cana ssp. viscidula and Artemisia tridentata ssp. spiciformis

Phytochemistry, 2002
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, 2007
While 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, 1988
We 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, 1973
Abstract 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, 1965
Acid 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.

Quantification of concavities in roots of Artemisia tridentata

Rhizosphere, 2018
Abstract Many publications have described the eccentric growth (non-uniform growth of secondary xylem) of stems of Artemisia tridentata that results from the death of the vascular cambium. The purpose of the present research was to determine if roots of species of Artemisia also exhibit eccentric growth. Eccentric growth in roots of Artemisia species

Allelopathic Characteristics of Artemisia tridentata and Purshia tridentata and Implications for Invasive Species Management

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, 1979
Abstract 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 .
