Survival and Growth of White Ash Families and Provenances 15 Years After Establishment in West Virginia

ISBN:
Category : Plants, Cultivated
Languages : en
Pages : 12
Book Description
The survival, growth, and stem form of 45 white ash (Fraxinus americana L.) families nested within 22 provenances were evaluated 1 5 years after establishment in North Central West Virginia. Geographic family origins encompassed a wide area in the eastern and central United States, including locations from Maine in the North to Mississippi in the South to Nebraska in the West. Significant differences were identified among provenances for survival, stem form, total height, and stem diameter and among families within provenances for stem form and total height. Latitude was a significant indicator of provenance performance with performance declining north and south of the plantation latitude. Performance gains may be realized by using proper provenances then identifying superior families within these provenances for white ash artificial regeneration activities.

Quantifying Foliar Responses of White Ash to Ozone and Simulated Acid Precipitation

Book Description
Seedling populations represent an important linkage for assessing the effect of air pollution on forests. This study examines the foliar responses of white ash seedlings to ozone and acid precipitation as a means of identifying atmospheric deposition effects on forests. With white ash seedlings, regression analysis revealed significant increases in foliar stippling, with rising ozone concentrations from 7 to 15 pphm. No stippling occurred in the absence of ozone or with acid rain treatment alone. However, exposure to ozone plus acid rain resulted in higher levels of foliar stipple as treatment concentrations increased. Until the inherent problems relating to the determination of the potential effects of air pollution on forests are resolved, the use of quantitative indices of injury to foliage and related growth impairments on susceptible and tolerant seedlings appears useful for assessing long-term ambient pollution effects on seedlings, trees, and forests.

Book Description
Excerpt from Silvical Characteristics of White Ash: Fraxinus Americana This species is the largest, commonest, and most useful-but not the most widespread-of the American ashes. Its natural range extends from Nova Scotia westward to Winona County, Minnesota, and southward to eastern Texas and northern Florida (fig. In eastern Texas it intergrades with the closely related Texas ash (f. Texensis (a. Gray) Sarg. F. Americana ssp. Texensis (a. Gray) Miller), but elsewhere in its range it is distinct from the other ash species (37, 38, 43, White ash has been planted abroad frequently as an arboretum tree but rarely as a forest tree. It has been successful when grown under conditions similar to those encountered in its native range. In England and France its performance compares favorably with that of the native European ash (f. Excelsior L. In native stands, white ash is frequently mistaken for green ash (f. Pennsylvanica from which it differs in having the white under-leaf surface, less sharp leaf serrations, and a cigar shaped seed with a terminal wing attachment. It is also confused sometimes with the pumpkin ash (f. Tomentosa from which it can be distinguished by the above three characteristics and by its generally smaller leaves, flowers, and fruit. The differences among the species are quantitative but nevertheless distinct. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
