ABSTRACT
Saffron (Crocus sativus) is the most valuable crop species in the world and is the only plant whose product is sold by gram. Saffron belongs to lrridaceae family and is geographically distributed in Mediterranean climates, East Asia (latitudes 30-50° N and longitudes 10° E to 80° W), as well as Irano-Touranian regions with low annual rainfall, cold winters and hot summers. While some species are grown for their beautiful ornamental flowers, cultivated species of saffron have great economic importance.
