Genetic Stability in Date Palm Micropropagation

Multiple bud cultures of ‘Barhee’ date palm (Phoenix dactylifera) and physiological status of regenerated plants

“…According to previous research work, the most genetically unstable date palm cultivar seems to be 'Barhee' (Cohen et al, 2004;Zivdar et al, 2008). However, the use of juvenile explants and low concentrations of 2,4-D can minimize the risks of somaclonal variation and generally ensure regeneration of morphologically uniform plants, as proven by the careful examination of fruits at the adult stage.…”

“…Somatic embryogenesis is now largely exploited, although literature related to organogenesis is still scarce. The in vitro propagation of date palm 'Barhee' is often hampered by somaclonal variations, as noted by Cohen et al (2004) after a multi-seasonal analysis of fruit setting, and also by Zivdar et al (2008) based on the results of isoenzyme analysis.…”
