ترجمة الملخص

A comparative study was performed on both plants species ( Malva) and (Papaver) at the locality of –Aljubah –District of (Slunfah) , governorate of Lattakia . This study focused on investigating the morphological , histological and pelynological differences between plants species growing on road side ( Exposed to pollution ) and those growing at a distance of 50 meters from road side. This study performed comparative analysis to detect concentration of some heavy metals ( lead, Iron, copper, nickel and Cadmium ) in the tissue of both flower and leave , and used two samples for the leaves and one sample for the flowers in each one of the plants species subject of this study .The chemical analysis revealed an altered content for some heavy metals in leaves tissues, according to thedistant of the studied plant sample from road side . Varying rates of metal concentrations were noticed in the studied elements as a function of distance separating said elements from highway . A rise in metal concentration values in these elements accompanied the elevated numbers of vehicles that pass the district in the second sample , which exactly applies on flowers . Results revealed as well, that plants growing on the road side are heavily polluted due to vehicles exhaust .-With regard to Malvaplant species, this effect was manifested by a reduction in plant length , leaf weight and surface area , the weight of wet sample and the water content . These harmful effects were seen as wellasin the production and reproduction properties of plant species , seen as reduction in flowers numbers and weight, beside weight and number of fruits . and the pollution effect was seen as a reduction in size and fertility properties of pollens , their number how ever was not affected . -With regards to Papaverplant species :Here, we noticed results similar to those seen in Malva plant , manifested as a decrease in stem length and diameter, leaf surface area, weight, size and its water content , in addition tothe reduced numbers of flowers , their weight , size of sepals and ovaries ,number and size of spikes in the plants growing on road side, in addition, pollution affected the Papaver plant through decreased number , size, fertility and length of pollen tube. 88Through arranging the histological sections for the stem and leaves in both studied plants, we noticed a deformation affected the parenchymal cells in the stem of (Malva) plant exposed to vehicles exhaust effect , beside defected parenchymal cells in the stem of (Papaver) plant exposed to the effects of vehicles exhaust on roads . Besides, we noticed defected spatial tissue and sub layers along with increased intervening distance in leaves of (Malva) this beside irregular cells morphology in the leaf spatial texture of (Papaver) plant under the pollution conditions . With regards to (50 m)plants tissues , we noticed regular cells morphology and no deformation was observed . This statistical study revealed that the differences in heavy metal concentration in both studied metals were of significance according to the distant of the plant position was from road side , this except copper element in the first sampling of (Malva) plant and Nickel element in the first sampling of (Papaver) plant species, There existed a gradient negative correlation between metal concentration in the leaf tissue and the distance from road in all studied elements . The correlation factors confirmed existence of strong negative correlation between the concentration of the studied element in flower and the distance from traffic road in all studied elements of both plants . Besides, there existed a strong negative correlation between concentration of the studied elements and different morphological and pelynological measurements .
