DOWNLOAD EBOOKMonoterpene composition was studied in a number of hard pine species and results were compared with earlier work. (I) Intratree measurements showed strong constancy of composition in both single-stemmed and forked trees of ponderosa, Jeffrey, Coulter, and Jeffrey x ponderosa pines. In grafts of these and other pines, the scion influenced the root stock, but not the reverse. (2) Large intcrtree variation in composition was found in a small sample of seven hard pines native to Mexico; the value of monoterpenes in clarifying taxonomy of these pines remains uncertain. (3) An 80-tree plot of ponderosa is adequate to determine average monoterpene composition. For the best estimate of the kinds and abundance of types of composition, a 350-tree plot is needed. Short-column chromatographic analysis is acceptably accurate for rapid classification of a large number of samples.

DOWNLOAD EBOOKFor hundreds of years, the massive ponderosa pine of the U.S. Southwest has left multitudes in awe. After spending nearly three decades researching among these trees, Sylvester Allred shares his wealth of experience in the southwestern ponderosa pine forests with the world in Ponderosa. Ponderosa is the first of its kind to provide an introduction to the natural and human histories of the ponderosa pine forests of the Southwest that is accessible to all who wish to enjoy the forests. The book offers knowledge on elemental aspects of the forests, such as the structure of the trees, as well as theoretical perspectives on issues such as climate change. Included are discussions of biogeography, ecology, and human and natural history, illustrated by over fifty color photographs throughout. Allred presents his observations as if he is recalling his thoughts over the course of a walk in a ponderosa pine forest. His imagery-saturated prose provides an informal and enjoyable approach to discovering the history and environment of the ponderosa pine. Using a concise, straightforward writing style, Allred invites readers to explore the forests with him. Ponderosa includes: More than 50 color photos Learn how to estimate the age of a tree See the reptiles, birds, and mammals that make their home in ponderosa pine forests Much more!
