The effects of the atmospheric pollution upon the green spaces and the vegetation of Piteşti municipalitythe plant, as well as on the street alignment of Pitesti municipality. At the first displacements themunicipalities of the localities under observation were informed, by written notifications, aboutthe objectives of the prosecuted researches, with the petition of signalling the apparition of toxicphenomena for the plants at agricultural cultures, regarding the edification on their nature, bothon the field and in the laboratory.The displacements were always effectuated during the first days of the month followingthe analysed one, in order to cover the evolution of the environment through the entire month. 26The soil and plant chemical analyses, executed according to the valid standards, as wellas the current practiced methodology practiced with the network of the Academy for Agriculturaland Sylvic Sciences Bucharest, were realised at SCCPT Albota and have been concerned withmaking obvious the nutrition condition, the eventual nutritious unbalances and their causes, inorder to specify whether the appeared phenomena are of toxicity and are due to the industrialprocessing of petroleum by the plant.According to the nature and concentration of noxa agents, the action upon plants ismanifested either on the contact parts, or producing lesions inside the parenchimatic tissues, casein which it affects the structural integration and also the essence of the physiological processes. 27The sensibility degree of plants to pollution is very different from species to species,from plant to plant within the same species, as well as according the various organs of the sameplant and the development stage in which the organs and plants are.All these aspects, starting from the respiration and transpiration process, up to thesensibility of plants to specific noxa agents, are related to genetics, time evolution and phaseevolution of the plants in each species.Plants’ resistance to polluters is given by the favourable environment conditions, by abalanced nutritive regime, as well as optimal pedological and hydrological conditions.In this context, the vegetative and phenologic development study of plants cultivated inthe influence area of the activity of industrial processing of petroleum developed by the plant, ascomponent part of the environment, has appeared as an objective necessity.For this purpose there have been effectuated various field displacements, displacementsthat have coincided with the main phases of vegetation of the plants, collecting information fromeach observance point, on a diversity of cultivated species as large as possible, species withdifferent sensibility to the action of the polluter factors and especially in critical phases of thevegetative evolution.Within the experiences we have effectuated studies and observations, soil and plantanalyses that have permitted a correct interpretation of all phenomena that have appeared in thegrowth and development of cultivated species of plants.The displacements and the field conclusions have been effectuated on each observationarea on the same date of the month, except the days when the meteorological conditions havebeen unfavourable. In these cases the displacement was done the immediate day that haspermitted it. These calendar days were the first 5 days of each month in which conclusions weremade and information was collected regarding the evolution of the plants during the previousmonth.Thus at Albota the displacement was realised on the 1 st of each month starting with Juneand ending with October, at Bradu the displacement was made on the 2 nd of each month, atCălineşti on the 3 rd of each month, at Căteasca on the 4 th , and at Oarja on the 5 th of each month.The team of specialists being numerous and complex enough, the observations andconclusions have concerned a complete research on the evolution of plants and cultures ingeneral. Part of these researches has been concerned with the pedogenetical qualities of the soil26 Bran, F., „Ecologie generală”, Edit.
