These links to Dr Deno's "Seed Germination: Theory and Practice" and the two supplemental books are free downloads at the USDA National Agriculture Library online site. I know this book is out of print and nearly impossible to find. I hope this information is useful.

You are welcome. ;)
Re: Link to pdfs of Dr. Denos seed germination books.
Has anybody told Norm that his handbooks are up on the USDA site and that the links are posted in the NARGS forum? I'm sure he would get a kick out of it!

I do not know Dr. Deno personally, it would be a pleasure to meet him. Please pass the word along to him with all of our thanks for writing such good references. I use them all the time.
Re: Link to pdfs of Dr. Denos seed germination books.
Me too! Thanks to Dr. Deno for an essential reference and completely fascinating reading!
Re: Link to pdfs of Dr. Denos seed germination books.
I have had the good fortune to meet Professor Norm Deno on a couple of occasions. Firstly, he arranged for me to give a talk to the Department of Horticulture, when visiting a cousin who was then Professor of Material Science at State College, PA (who played an integral part in the development of ultrasound equipment) during a lecture-tour in the mid-1980s. Secondly, I was driven across from Philadelphia, whilst being hosted by Joyce Fingerut in 1990.
Whenever I cover cultivation in my lectures I state that his books should be required reading for anyone taking a serious interest in seed germination. I learnt a lot from his seed germination experiments approached from the perspective of a chemist. Cannot be read from "cover to cover" at one go - even for those with a Scientific background but are well worth "dipping" into on a regular basis and persevering with, even if they appear "heavy going" initially. Full of gems of wisdom - and amusing comments about us botanists!
I regularly draw attention to his recommendation that the word "stratification" be abandoned and that it is not a period of "freezing" but "chilling" which some seeds require - most species from the Himalaya (at least after a period of dry storage) have no such "chilling" requirement and can be sown in Spring or early summer with perfectly good rates of germination.
This is a excellent resource, thanks for posting this John!
I don't have the book, always wanted a copy, so its fantastic that it is now freely available online. I edited you alert regarding the site being down, as it is working now. Because of the importance of this topic, I am setting it to be a "sticky topic", a NARGS Forum term which means to pin the topic so that it always appears at the top of the Propagation topic.
