Excerpt from Quaking Aspen: Seed Germination and Early Seedling Growth Although freshly dispersed aspen seeds germinate quickly and nearly completely over a broad range of temperatures, early growth of seedlings is highly sensitive to availability of water, temperature, and physical and chemical conditions of the seedbed.

The first comprehensive handbook on the seeds of trees and shrubs produced by the USDA Forest Service was USDA Misc. Pub. 654, Woody-Plant Seed Manual. The manuscript was ready for publication in 1941, but World War II delayed publication until 1948. The boom in tree planting in the 1950s and 1960s created a large demand for seeds and exposed the gaps in our knowledge concerning production and quality of seeds of woody plants in general. The 1974 Handbook proved to be very popular both in this country and abroad, leading to five printings and translations in several other languages. More than a quarter-century after its publication, however, numerous advances in tree seed technology have dictated that a new revision is needed; the result is the current volume. Part I contains information on how to get seeds and raise seedlings. Get Your Copy Now.

This is the first truly modern book solely devoted to seed reproduction of forest trees-from flowering to establishment, with emphasis on the interaction of environment with physiological processes. Focus is on seed function in natural settings and the application of information to natural regeneration of forests. This easy-to-read text addresses important principles and provides in-depth coverage of existing literature. Presentation of the information is organized to allow for a natural development of the main theme with full explanations of such important components as seed production, dispersal and germination, as well as the integral parts played by water, temperature, light, chemicals, animals, pathogens and aging. A highly useful book for investigators, practitioners or students.
