REPORT OF THE SURVEY STUDIED ON SOMACLONAL VARIATIONS IN IN VITRO PROPAGATED DATE PALM PLANTS

A. Abutalebi
In vitro production using either the process of somatic embryogenesis or organogenesis has been established in recent years as a routine procedure in several commercial laboratories to produce large numbers of date palm plants at a competitive cost. The date palm micro-propagation process, like other large-scale commercial plant production processes, carries a number of risks. Off type, i.e., non true to type and genetically not identical to the mother plant, may be among the resulting plants. This report was a survey studied in a date palm orchard containing 2000 plants of two cultivars (‘Piarom’ and ‘Mejdhool’) of five years old of in vitro propagated date palm plants. Various somaclonal variations appeared. Different growth rate and differences in plant shape appeared at a high level in the two cultivars. Dwarfism, morphological abnormality, chlorosis in one side of the leaf, growth point bending, leaves rotating, leaflet chlorophyll losses (albinism or variegation), abnormality of growth point, leaf malformation, death of terminal growth point (hypoxanthic palm), high vigorous plants and plants with poor establishment were observed in the two cultivars.
