Abstract

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.
