The experiment was carried out on Gerbera jamesonii cv. Estafette (red inflorescence) and Essandre (yellow inflorescence), to investigated the effect of different concentrations of plant growth regulators include: Benzyl adenine (BA), Cycocel (CCC) in combination with four preservatives solutions which include: distilled water, 10% sucrose, 400 mg.l-1 8-hydroxy quinolinsulphate (8-HQS) and solution contain 10% sucrose+400 mg.l-1 8-HQS. The factorial experiment was conducted by using complete randomized design. Each treatment was replicated three times with four inflorescences for treatment. The results showed: that there were significant differences between cultivars in vaselife, Estafette inflorescences stay 9.57 days compared with 8.68 days for cv. Essandre inflorescences. On other hand, spraying the plants with 250 mg.l-1 increased vaselife to 9.84 days. In general, the inflorescences taken from plants sprayed with BA at 250 and 500 mg.l-1 for Estafette cultivar and 250 mg.l-1 for Essandre, then holding in solution contain 10% sucrose and 400 mg.l-1 8-HQS gave best results 12.50, 10.50 and 10.0 days vase life, respectively, lowest decrease in fresh weight percent and bent neck.
