Re: Re Mycorrhizal Fungi and Mycorrhiza

Your story recalls a research report I came across decades ago of a success story using mycorrhizal fungi to inoculate pines
in, I believe, Puerto Rico. The pines were not indigenous, and the scientist involved was Dr. Ed Hacsklayo (whom I had the
honor to meet when we were both working at the USDA facility in Beltsville, MD). In this case, inoculation resulted in
dramatic increases in growth. The study may have been mentioned in an article he wrote for Bioscience 22(10):577-583, 1972.
