In vitro molecular and cytogenetic study of some Egyptian date palm (Phoenix dactylifera L.) cultivars.
Five Egyptian date palm (Phoenix dactylifera L.) varieties were used in this study, i.e. Ammry, Agglani, Zaghloul, Sewi and Ferehi. This work aims to test the biochemical variations and chromosome instabilities and abonrmalities during callus formation in in vitro culture techniques for those five varieties. The study of somaclonal variations were done through: 1- studying peroxidase isoenzymes from callus and primary leaves 2- cytological examination of callus cells suspensions. Results showed some somaclonal variations due to tissue culture exhibited as variablity in band numbers and activities of peroxidase isoenzymes and chromosome numerical aberrations in callus cells
