Effects of Soaking, Washing, and Warm Pretreatment on the Germination of Russian-Olive and Autumn-Olive Seeds

There is evidence that water-soluble inhibitors in seed coats are in part responsible for seed dormancy in some Elaeagnus species. The effects of washing, soaking, and moist warm pretreatment on germination of Russian-olive (E. angustifolia L.) and autumn-olive (E. umbellata Thunb.) seeds are reported in this paper. Autumn-olive seeds were not particularly dormant and germinated without pretreatment. However, germination of the more dormant Russian-olive seeds was improved by washing the seeds in tap water for 6 days prior to prechilling. A similar proportion of seeds also germinated during warm pretreatment in peat and sand without prechilling.
