Asexual Vs. Sexual Propagation Of Quaking Aspen, Robert B. Campbell Jr.

Aspen Bibliography

ABSTRACT: Quaking aspen (Populus tremuloides Michx.)

regenerates almost exclusively by root suckers in the

western United States, even though female clones

produce abundant viable seed. During the past decade,

interest in propagating aspen for use as an

ornamental and for revegetation of forest land has

increased. To satisfy these diverse needs for aspen

planting stock, nurserymen have a choice between

sexual and asexual propagation. Criteria for clone

selection, suggestions for root and seed collection

and storage, propagation techniques, and the

advantages of both sexual and asexual propagation are

discussed.

Simulation Of The Daily Growth Of An Aspen Population From The Measured Co2-Exchange Rates Of The Components, G.C. Bate, D.T. Canvin

Aspen Bibliography

The daily total CO₂-exchange of an aspen population (32 trees) was measured using a growth chamber gas analysis system which had been shown to measure accurately the actual carbon gain of the population. The CO₂-exchange rates of the components (e.g. roots, stems, leaves) were measured in the light and dark and these rates were used to calculate the total CO₂-exchange of the population using a computer model. The carbon gain during the photoperiod was underestimated by 25% in the simulation while the carbon loss during the nyctoperiod was overestimated 100% by the simulation.

The Effect Of Range Condition Upon The Production, Nutritive Intake And Digestibility Of Desert Range Forage In Southwestern Utah, J. Kent Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The 65 million acres of winter range in the Intermountain region furnish forage for about five million sheep and four million cattle each winter for approximately six months. These arid ranges are well suited for winter grazing, and are of paramount importance to the livestock industry. Many of these ranges were fully stocked by 1900 and as livestock continued to increase, many winter ranges were seriously over-grazed (Hutchings and Stewart, 1953). Today many of these ranges remain in a deteriorated condition. Forage production has decreased and desirable plants have been replaced by less desirable species.
