INVESTIGATION THE PROTEIN PATTERN OF LEAVES AND ROOTS OF BARHI AND KHALAS DATE PALM (Phoenix dactylifera L.) CULTIVARS PROPAGATED BY OFFSHOOTS AND TISSUE CULTURE TECHNIQUES

The present study was conducted to investigate the protein pattern of leaves and roots of Barhi and Khalas date palm cultivars propagated by offshoots and tissue culture plants and grown in one of the private orchards in Ktaban region in Basrah governorate, Iraq. Results of the protein pattern showed that protein bundles on polyacrylamide gel were differed by their molecular weights, the number of protein bundles ranged from 6 to 8 according to the female cultivar, propagation method and plant part used.Leaves and roots of Barhipropagated by offshoots and tissue culture techniques showed the same site and molecular weight for the first protein bundle 220.000 KDa and for the second protein bundle 222.976 KDa. The cluster analysis of the two cultivars propagated by offshoots and tissue culture techniques depending on the molecular weights of the protein bundles showed two main groups with the degree of difference between them amounting to (7.5%), the first main group included Barhipropagated by offshoots and tissue culture techniques, for both leaves and roots. Whereas Khalas propagated by offshoots and tissue culture techniques, for both leaves and roots grouped in the second main group.
