Hydrogen Peroxide Increases Germination and Reduces Microflora on Seed of Several Southwestern Woody Species
Washing seeds of Pinus ponderosa Laws., P. edulis Engelm., Juniperus monosperma (Engelm.) Sarg., Atriplex canescens James, Cercocarpus montanus Raf., and Cowania mexicana Gray in water for 48 hours, followed by a half hour soak in 30 percent hydrogen peroxide, increased the germination of all species except A. canescens. Soaking in water, followed by the peroxide treatment, improved the seed germination of four of the species. Soaking or washing without the peroxide treatment proved less effective; in fact, most water treatments were detrimental to A. canescens and C. montanus seeds. The peroxide treatment effectively reduced seedborne microflora, but induced some abnormal seedling development of the three shrub species.
