The tulip (Tulipa sp.) is an ornamental plant produced by bulbs. Wild tulips are native to several areas of Iran, especially the Alborz and Zagros mountains. Endemic Iranian tulips are the origin of some commercial cultivars of tulip, and mutagens are commonly used to produce new traits and varieties. In this trial, X-rays were applied at 60, 70 and 80 kV; sodium azide (SA) at doses of 0.01%, 0.02%, and 0.03%, and diethyl sulfate (DES) at doses of 0.1%, 0.2% and 0.4 on Kess Nelis and Jan Van Ness varieties of tulip. Morphophysiological traits of the treated plants were measured. The results showed that application of DES increased the fresh weight and number of bulbs, and decreased the number of offsets, main stem length, leaf area, and total fresh weight. The results showed that SA had a positive effect on most traits. All three doses of DES increased the flower longevity and all had an inverse effect on the anthocyanin content of the petals.
