Abstract

Iran is one of the most important regions for origin and diversification of wild almond species in the world. Over 20 species, naturally distributed in many regions, have been identified to date in Iran. These can be used as rootstocks in different Prunus species such as almond or peach due to their adaptability to severe (drought) environmental conditions and resistance to some pests and diseases. Results showed that P. eburnea had the most stem biomass, and P. scoparia the least leaf area and the largest root system among the three species, which can indicate better adaptation to drought conditions. The correlations between the measured traits suggest that the relationship between shoot and root morphology is unique for each species. In addition, results indicated that P. eburnea had the highest seed germination percentage and P. elaeagnifolia the lowest. Finally, there was significant difference between wild rootstocks in grafting success, with P. scoparia and P elaeagnifolia showing the best behavior.
