توزيع گونه هاي AEGILOPS بر حسب ارتفاع در ايران

Attitudinal Distribution of Aegilops species in Iran

Geographical and altitudinal distribution of 234 populations belonging to 13 species of Aegilops in Iran after chromosome counting was studied. The relation between different ploidy levels, genome types and altitudinal distribution was estimated. Results indicate that D genome type and tetraploids are much frequent at higher altitudes. Among the Aegilops species in Iran, Ae. kotschyi and Ae. tauschii Are low land elements while Ae. crassa prefers the highest altitude from the sea level.
