Book Description
Excerpt from Self-Fertility of a Central Oregon Source of Ponderosa Pine Germination tests were conducted using seeds with full-sized embryos (i. E. Seeds with embryos greater than three quarters the length of the embryo cavity). Except for five families which had too few seeds, 100-seed lots were germinated in a commercial germinator at 30° C. Day temperature and 20° C. Night temperature with 12-hour photoperiods and thermo periods. Prior to germination, seeds were stratified for 3 weeks at 5° C. The germination test was discontinued when no germination had occurred for a period of 1 week. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
