Abstract
Tropospheric ozone is a known phytotoxic pollutant. In the present study effects of ambient ozone were monitored on common bean (Phaseolus vulagris) cultivar S156 (Ozone sensitive) that was obtained from ICP vegetation UK and four local cultivars of Mung beans (Mung NM-11,Mung NM-06, Mung Chakwal-06, MungNCM-257-2) that were obtained from NARC, Islamabad. The main aim of this experiment was to observe if the ozone injury symptoms appear on any of the four local cultivars of Mung beans. These ozone injuries were compared to sensitive cultivar of common beans (S156). The experiment was conducted in Fatima Jinnah Women University in summer season (April to July, 2013). Ambient ozone concentrations were recorded 8h/day by using the Photometric Ozone Analyzer (Model 400E). Ozone concentration ranged between 10ppb to 60ppb during the experiment. Results showed that sensitive cultivar (S156) was directly affected by ozone exposure and started showing foliar ozone injuries in 4th week of experiment while similar ozone injuries appeared only on Mung NM-11 that showed the ozone sensitivity. No ozone injuries were recorded on other three varieties of Mung beans. Therefore, Mung NM-11 is recommended as bio monitoring plant for specific ozone injury in Pakistan.Biography
