[en] Hyperhydricity is a serious problem faced in vitro date palm propagation which directly effects on the commercial production. So we try to solve this problem by studying, the effect of glutamine as the organic source of nitrogen and NH₄⁺ :NO^3- ratio as the inorganic source of nitrogen to decrease hyperhydricity phenomena and to produce normal somatic embryos of date palm cv. Gondila.Vitrified embryonic callus were inoculated on MS basal nutrient medium modified with glutamine levels and NH₄⁺ : NO₃^- ratio. Five concentration ratios of NH₄ : NO₃ (10:15, 15:10, 0:20, 20:0, 0:0 ml/l) were used with 0.1 mg/l NAA for 8 weeks throughout 2 recultures. There were gradually increasing in the percentage of vitrified embryonic callus differentiation to normal somatic embryos by increasing glutamine levels from 0.0 to 400 mg/l. Glutamine at the lowest level (50 mg/l) increased significantly the number of vitrified somatic embryos. Ammonium as the sole source of N resulted in depression in somatic embryos differentiation and escalated the frequency of hyperhydricity whereas,if nitrate was used as the sole N source, somatic embryos good quality were produced and hyperhydricity was eliminated
