| Abstract | ||||
| Metabolic sugar (sucrose. glucose and fructose) and nutrients (MS formula) were found 10 affect polyphenol accumulation in date palm somatic embryos through conservation period (10 month) incubaled under total darkness at 18°C, while alcoholic sugars (polyols) sorbitol and mannitol had no eftect on this respect. Increasing the sugar content and reducing the nutrients content or culture media both enhanced the content of the phenolic substances Also raising the cone ntration of ABA in conservation medium from 3.7 to 30 liM in conserved media induced excessive accumulation of phenolic compounds. Healthy and succeeded conserved embryos exhibited good growth during in vitro and ex vnto stages. | ||||
