N2  - The present research was were carried out in the Flowers and Ornamental Plants Research Gardens. Department of Floriculture , Ornamental Horticulture and garden Design, Faculty of Agriculture, Alexandria University throughout two successive seasons 2005 and 2006. Origanum majorana L. was chosen for this study because of the importance of its essential oil, their medicinal and aromatic uses. The experiment was carried out to determine the effect of plant growth regulators on the quality of the essential oils of Origanum majorana L. Nine treatments consisted of four different concentrations of GA₃(50, 100.150 and 200 mgL⁻¹), four different concentrations of Kinetin (10, 20, 50 and 100 mgL⁻¹) and the control treatment were applied. Regarding the effects of applying Gibberellic acid. it was found that,spraying plants with GA₃ at the rate of 200 mgL⁻¹ gave the highest percenta~e of terpinene in marjoram leaves in the two seasons. Using GA₃ at the rate of 150 mgL⁻¹gave the highest percentage of terpinene in ma~oram racemes in the first season and GA₃ at the rate of 100 rngL'1 in the second season
