ABSTRACT

The tropospheric ozone is recently reported to be one of the most important air pollutants. Many methods and experiments have been designed to measure the tropospheric ozone concentration and to determine its influence on living organisms. The most sensitive bioindicator of ozone is the tobacco plant (Nicotiana tabacum L.). The physiological reaction of this and other plants to ozone are recently the subject of intensive studies. During experiments with tobacco, plants of two different cultivars were in two series exposed to ambient air for a time period of 14 days. After exposure the following parameters were measured: daily growth of plants, percentage of leaf injury, dry matter, chlorophyll and salicylic acid content. This method of ozone biomonitoring based on two tobacco cultivars of different susceptibility to ozone not only gives the unique opportunity to measure a visible effect on plants, but also to establish the mechanism of physiological reaction. Plants used for testing showed visible leaf injury, decreased in growth and chlorophyll content, increased in dry matter and salicylic acid content as the result of reaction to higher ozone concentration.

Key words: tobacco plant, tropospheric ozone, bioindication, chlorophyll, salicylic acid.
