In this study, the effects of low temperature and GA3 were investigated on the bulb forcing and quality of Narcissus. Temperature and GA3 were studied in two (4℃ for 12 weeks and 23℃) and four (0, 200, 400 and 600 ppm) levels, respectively. The experiment was performed at Faculty of Agricultural Sciences, University of Guilan, Rasht, Iran, in 2006. The results indicated that sprouting occurred faster (9.34 days) in bulbs treated for 12 weeks at 4℃ than those non chilled (34.34 days). Moreover, low temperature treatment reduced flowering time (37.06 days). Vase life was much shorter in chilled bulbs than none chilled. GA3 reduced the sprouting period more than control treatment (0 ppm), so with increasing GA₃ concentration, sprouting was decreased (r² = 0.74). However, the effects of GA₃ on the flowering time and quality of flowers were not significant. Temperature × GA₃ interaction was not significant on the all studied traits. Results from this study showed that chilling of Narcissus bulbs prior to planting may be used as an effective treatment to overcome dormancy and promote uniformity in bulbs sprouting.
