Abstract
The aim of the paper was to assess the impact of different stratification treatments recommended by the literature on the shortening of manna ash (F. ornus L.) and narrow-leaved ash (F. angustifolia Vahl.) seed germination in order to identify a suitable pre-germination treatment for seedling production. Seeds of three Southern Romanian origins for both species were exposed to four stratification treatments (cold (3oC) and warm (20oC), with and without sand-peat medium). The highest percentage of germination (up to 87% for Fraxinus ornus and up to 71% for F. angustifolia) was recorded in the case of the stratified seeds with cold medium (3oC) and relatively constant seed moisture (between 45% and 65%) throughout the treatment.
