Fitoindication of contamination of roadside territories of Republic avenue on the state coniferous arboreal breeds

Abstract

In hired the results of bioindication research of roadside territories of Republic avenue of Astana city are presented
on the state a pine-tree usual- Pinus sylvestris and fir-tree European- Picea abies. On the row of morphometric descriptions
(chlorosis, necrosises of pine-needle, change of escapes, reduction of reproductive organs etc.) oppressing of coniferous arboreal
breeds is educed exhaust gases of cars in municipal terms. Pine needles have various kinds of chlorosis and necrosis up to 40%.
Spruce chlorosis and necrosis up to 10% are observed in the fir. Almost at all sites there is a decrease in the weight of needles
to 69%, which indicates necrosis of the biomass of trees. There is a tendency for the distance between the needles to be closer
to 10 cm of shoot, so the number of needles is almost 1 to 2 times higher in contaminated areas than in control samples.
