Abstract:
Flax (Linum usitatissimum) were studied at three types of soil collected from new sites in Egypt (Western Mediterranean Coastal region, East of El-Kantara in Sinai, and Tushki is the new valley). The plants were subjected to a pot experiment cropped with Linum. Physical and chemical analyses were carried out for each soil. The effect of different soil types on growth criteria, total leaf conductivity, transpiration, photosynthetic pigments, ionic contents and the rate of transport of elements, percentage of fiber as well as protein pattern and fatty acid contents of the yielded seeds were studied. The growth of flax plants at various soils led to a significant decrease in all growth criteria and total pigments, however, total leaf conductivity and transpiration rates were increased at El-Kantara and Tushki sites and decreased at Northern Coastal site comparing with control. Comparing, the three soils, it was apparent that, at Northern Coastal site, there was a high seed yield than the other two sites. At El-Kantara, there was high percentage of fiber than the others. The amount of oil recorded a highly significant increase at Northern Coastal and Tushki site, while a significant decrease at El-Kantara site. The rate of transport of elements (Jj) for K, Na and Ca showed a significant decrease except for Jj Na and Jj Ca at Northern Coastal and for Jj Na at El-Kantara site. Variable changes were obtained in the composition of polypeptides with a wide range of molecular weights and for the constituent saturated and unsaturated fatty acids.
