Chapter 7 - Principles of Propagation From Seeds
Looking at a just-germinated seedling it can be difficult to grasp the complex interaction of environmental ques and biological processes that must occur in a precise sequence which allowed the seed to germinate. In fact, what precisely denotes "germination in orthodox seed?"
In this chapter you'll learn the "phases" of seed germination, how to determine the germination characteristics of a seed "lot," and how to indentify and overcome various types of seed "dormancy."

While becoming a bit dated, this review article will provide you with an exellent discussion of seed priming techniques. Of particular value are the exhaustive list of references cited.
Supplemental Online Resources:
"Seed Dormancy in Commercial Vegetable and Flower Species" (link)
This article frames the discussion of seed dormancy as it relates to common vegetable and flower species. Therefore, it might be useful in helping you grasp the wide range of seed dormancies and hope to overcome them.
"The Seed Biology Place" (link)
This link takes you to the seed dormancy section of an extensive seed biology website maintained by the students and staff of the Gerhard Leubner Lab at Royal Holloway University of London. The descriptions of the various seed dormancies are quite straightforward and may be helpful to review.
