Abstract

The environmental damage to Kuwaiti flora was studied. Four Kuwaiti desert flowering plants, Picris babylonica, Launaea mucronata, Senecio glaucus, and Sonchus oleraceous, which suffered mutagenic modifications with changes in tapetal cell characteristics, were selected for this study. Changes in growth parameters, such as photosynthetic pigments, proteins, free amino acids, phenols, and reducing sugar levels, which could have resulted from the observed genotoxicity of oil pollution, were studied. P. babylonica showed marked differences in the levels of the above parameters as compared to the other three plant species. In P. babylonica, levels of phtosynthetic pigments, reducing sugars, proteins, plamitate/stearate, Linoleate/stearate, and linolenate/stearate fatty acid ratios were higher than in the corresponding plant species collected from control areas away from blazing oil wells. On the other hand, in P. babylonica, the levels of phenols and free amino acids were lower as compared to the plants collected from the control area. It appeared that the level of these parameters was dependent on the level of photosynthetic pigments.
