COMPARATIVE ANALYSIS OF THE ABILITY OF FLORA URBAN AREAS TO ACCUMULATION OF HEAVY METALS
The paper studies the ability of trees and shrubs in urban areas to absorb heavy metals. The study was identified Election ability of some species of flora in the city of Orenburg and Buzuluk to the accumulation of copper and zinc.
Key words: soil contamination, phytoremediation, heavy metals, urban ecosystems.

ACCUMULATION OF HEAVY METALS WILD APPLE TREE (MALUSSYLVESTRIS) IN BUZULUK
With increasing urbanization is changing urban environment, which differs in many respects from the natural environment. Heavy metals occupy a special position, because, not subjected to physico-chemical or biological degradation, accumulate in the surface layer of the soil and change their properties, for a long time are available for root uptake by plants and actively participate in the processes of migration in trophic chains.
Key words: heavy metals, аpple, sustainability, and the accumulation.

ECOLOGICAL AND BIOGEOCHEMICAL EVALUATION OF FRUIT PLANTINGS OF BUZULUK ORENBURG REGION
As a result of industrial, agricultural and other human activities there technogenic migration of significant amounts of various substances, most of which pollute the environment. These substances include heavy metals (HM) — mercury, cadmium, lead, arsenic and zinc. Large proportion of them are accumulated in the vegetative parts of plants to limits. Monitoring and assessment of the impact of TM in plants is a necessary condition for improving the environmental safety of food.
Key words: heavy metals, the maximum allowable concentration, fruit, mountain ash, apple, rose hip.

HEAVY METAL CONTENT OF APPLE FRUITS IN URBAN ENVIRONMENTS
Fruit trees are widely used in greening settlements. The increasing pollution of industrial emissions, traffic flow lead to environmental pollution and the accumulation of heavy metals in soil, leaves, wood and fruits. We found marked selectivity of certain forms of apple trees to heavy metals, a significant excess of the maximum permissible concentration.
Key words: heavy metals, apple, ecology, lipids, sugars, selective accumulation.

HEAVY METALS IN SOILS AND PLANTS OF STREETS OF BUZULUK (ON THE EXAMPLE OF THE MOUNTAIN ASH ORDINARY)
Monitoring and assessment (including negative) influence cha-and metals and soluble forms of their toxic compounds in the living body a necessary condition for the present time. The urgency of this problem is obvious, as for heavy metals, in principle, there are no mechanisms of natural self-purification and their accumulation is dangerous for the living organism.
Key words: heavy metals, maximum permissible concentration, atomic — adsorption spektrofotometria.

STUDY OF PHOTOPERIODIC RESPONSES OF PLANTS GROWING IN BUZULUK AND BUZULUK DISTRICT
Central moment of development of plant organisms is transfer from vegetative growth to reproductive development (with respect to flowering plants — to flowering). The basic factor of environment which impacts transfer of plants to reproduction — flowering, is duration of daylight illumination. This dependency of transition to the flowering phase from day length is called photoperiodism.
Key words: photoperiodism, day length, reproductive development, dormant state.
