| Résumé: | In a survey study on some tissue culture-derived date palm cultivars (Medjool, Barhee, Sukkary, Toory, Deglat-Noor, Khalas, and Nabtat-Saif), somaclonal variations were observed. Dwarfism, slow growth, morphological abnormality, terminal bud bending, fruit set failure (shees), and supernumerary carpels were the most common phenomena. The type and percentage of variations differ among cultivars. The fruit set failure and dwarfism highly occurred and caused an economical loss. The Occurrence of fruit set failure varied between 20-100%, and number of carpels was between 4-9 carpels, except cvs. Medjool and Toory which were highly produced fuits. Whereas dwarfism was between 3-25% depending on cultivars. Morphological abnormality and terminal bud bending were the highest in Sukkary (10-50%). Albino and leaf variegation were very low (1-3%). Many offshoots were detached from Tissue cultured-failed to set fruit trees of Barhee behaved like their mother and failed also to set fruit and had supernumerary carpels. |
