A Field Test of Douglas-Fir, Ponderosa Pine, and Sugar Pine Seeds Treated with Hydrogen Peroxide

Hydrogen peroxide can speed germination of many conifer seeds. This capability has been used in the laboratory and might also promote fast germination in the field. The experimental sowing described provides clues about possible field use of peroxide-treated seed. Prior to the research reported here, hydrogen peroxide had been used on conifer seeds to achieve one or more of three objectives: (1) To rapidly test seed viability, (2) to surface sterilize seed used in cultures, and (3) to obtain seedlings quickly for experimental trials. Ching and Parker (1958) first reported using weak hydrogen peroxide solutions to rapidly test the conifer seed viability of Douglas-fir, ponderosa pine, sugar pine, Jeffrey pine, lodgepole pine, noble fir, grand fir, and white fir. They opened the radicle end of each seed prior to immersion and germination in dilute hydrogen peroxide solution.
