Effect of different chemical treatments on quantitative characteristics of Polianthes tuberose L. (cv. Goldorosht Mahallat) was investigated. This research was conducted in a factorial experiment based on block design with 3 replications. 40 and 54 days after planting, the flowers were sprayed with various concentrations of Gibberellic acid (GA₃) and Benzyladenine (BA) (0. 50. and 100 ppm). The results showed that. flowering stem length and leaves length were greatest with GA₃ at 100 ppm while BA no increase these traits compared to the control. GA₃ resulted in earlier flowering compared to the control. BA and GA₃ decreased number of floret. Greatest diameter of floret and vase life of cut flower was BA at 50 and 100 ppm, respectively.
