ПАЛІНОІНДИКАЦІЯ АТМОСФЕРНОГО ПОВІТРЯ М. ЧЕРНІВЦІ

Abstract

The monitoring evaluation of anthropogenic transformation level of the environment was made according to viability of pollen Malus domestica Borkh. and Prunus cerasus L. The research was conducted in 2015-2017. The monitoring areas were located on the territories of preschool- and general educational institutions of Chernivtsi city. The pollen of the plants, which grow in locations of the background territory (landscape wildlife preserve Tsetsyno), was used as a control. As the result of the research, it was found out that the increase of anthropogenic loading level caused the productivity rise of sterile pollen grain. It was also discovered that M. domestica has a higher sensitivity than P. cerasus due to its capacity to produce fertile pollen with mean concentration of starch as a response to the atmospheric pollution. The mentioned feature of M. domestica expands the opportunities of its use as a bioindicator and also can indicate the anthropogenic transformation of environment. According to the integral conditional index of bioindicator’s damage, it was assessed that a satisfactory state of environment is on the Nebesnoi Sotni 18-A st., F. Poletaeva3 st., Saltykova-Shedrina29 st., Ruska178 st. and Nebesnoi Sotni 10-B st., when an ecological situation in other monitoring areas corresponds to the standards of cleanness. The main reason for the increase of pollen sterility of the bioindicators on the above-listed streets is a close proximity to the highways with an active traffic and traffic congestion.
