In this study, effect of gibberellin inhibtors as preplant bulb soaks on plant height of Narcissus cv. ‘IceFollies’ grown in pots were investigated. Bulbs of Narcissus cv. ‘Ice Follies’ were soaked in flurprimidol at 0, 10,20 ppm and paclobutrazol at 0, 100, 200 ppm before planting. Effect of gibberellin inhibitors on the time of flowering,flower life, chlorophyll content of leaves, leaf length and plant height were determined. In addition, after narcissuswere grown in pots in the greenhouse arrived at the sales stage to determinate the changes that occur in the plantheight, plants were taken to the laboratory which was temperature held constant at 20 °C. The shortest plant heightwas obtained from the 20 ppm flurprimidol, 200 ppm paclobutrazol and 10 ppm flurprimidol treatment as given bulbsoaks. In this treatments, plant heihgt was 7.11, 7.31, 7.75 cm and were 52%, 51%, 48% shorter than untreatedcontrol. Gibberellin inhibitors also shortened leaf lenght. Flurprimidol and paclobutrazol treatments were resultedhigher chlorophyll content per unit area in the leaves than untreated controls. The highest chlorophyll content wasobtained from the plants were treated 20 ppm flurprimidol with 60.6 CCI, while the control was 40.96 CCI. Theeffects of treatments on plant height has been maintained in lab conditions (home-office). The shortest plant heightwas obtained from 200 paclobutrazol treatment with 10.12 cm during post production period.
