| Abstract | ||
| Shoot tips and callus of some cultivars of date palms (Phoenix dactylifera L.)were cultured on MS (Murashige and Skoog) and GM5 (Gambourge B5) media byusing auxin IAA mainly and other auxins NAA, 2,4-D and IBA.The results showed a significant superiority of cultivar Hillawi than CVS.Zahdi, Barhee, Braim and Khasab for growth value and dry weight of shoot tipsegments. There is a significant superiority of auxin IAA in MS medium than both IAAand 2,4-D in GM5 for growth value and dry weight for shoot tip segments of CV.Hillawi, and significant superiority of auxin IAA at level 100mg/L than auxin NAA(100mg/L) for growth value and dry weight of shoot tip segments of cv. Hillawi , andalso a significant superiority of auxin IAA (10mg/L) than IAA at levels (0, 25,100mg/L) for growth value an dry weight of both shoot tips segments and leavesprimordia of cv. Sayer. Finally there is a significant superiority of auxin IAA (10mg/L)than auxins NAA, IBA and 2,4-D at the same levels for growth value of embryogeniccallus of cvs. Barhee and Hillawi whereas the superiority was for both IAA, NAA, thanthe rest auxins for embryo length for cvs. Barhee and Hillawi | ||
