In this study, mungbean [Vigna radiata (L.) Wilczek] was exposed to charcoal filtered air (FA), unfiltered air (UFA) and ambient air (AA) treatments in open-top chambers (OTCs). The vegetative growth and development assessed periodically at three different growth stages spending a period of three months. The growth and development of bean showed distinct different responses to O3 and NO2 depending upon treatments (FA, UFA & AA). Early growth suppression and slow increments at reproductive stage were clearly evident in plants under ambient air conditions. An extended vegetative growth phase in FA treatment lead to delay in onset of appeared earlier in AA and UFA treatments by a difference of 7 and 5 days, respectively as compared to pollution free treatment (FA).
