Abstract:
Quercus emoryi Torr. (emory oak) and Quercus arizonica Sarg. (Arizona white oak) are the dominant tree species in many of the oak savannas and woodlands of Arizona and northern Mexico. Objectives of this study were (1) to evaluate germinability on two media as influenced by storage and stratification, and (2) to determine effects of oak canopy and depth of burial on acorn viability and germination. Germination was higher (P < 0.05) on filter paper than in mineral soil in laboratory trials. Maximum germination of Quercus emoryi in the field was observed at 7.5 cm (29%), with only 5% germination at the soil surface. Germination of Quercus arizonica at 7.5 cm (73%) and 15 cm (74%) were not different (P > 0.05) but exceeded germination at the surface (17%). These results are applicable for propagation of the two species in a tree nursery.
