Dr. Orland E. White, Blandy Experimental first Director, began collecting ginkgo
seeds in 1929 from a single “mother tree” on the University of Virginia Grounds in Charlottesville. After these seeds germinated, Dr. White’s students planted over 600 ginkgo saplings to determine the sex ratio of this tree. Most plants are both male and female, but like holly, persimmon, and other species, ginkgo is dioecious, meaning a tree is usually male or female, but not both. Dr. White hypothesized the sex ratio would be
1:1. He did not live long enough to find out if he was right, but of the 301 trees that survived to maturity and for which gender could be determined, 157 were female and 144 were male. Statistically speaking, this does not deviate significantly from1:1. "
