ABSTRACT
Increased tropospheric O concentration is main factor affecting world agriculture production. In present investigations it 3 has been investigated the affectivity of ethylene diurea (N-[2-(2-oxo-1-imidazolidinyl) ethyl]-N-phenylurea; EDU) treated mungbean plants (Vigna radiate L.) against ambient ozone and to assess the effects of ambient ozone by atmospheric pollution tolerance index (APTI) on mungbean plants grown under field conditions and on some biochemical parameters. During the experimental period, monthly mean O concentration varied between 79.4 ppb and 3 105.2 ppb. Substantial reduction in mungbean crop productivity under ambient conditions in contrast to EDU and N- EDU-treated plants was recorded. Significantly good results by the application of EDU were seen in order to observe photosynthetic pigments and air pollution tolerance index (APTI). The study validated that EDU lightens the unfavorable O effects on mungbean crop and EDU can be utilized as a very useful tool to investigate agricultural crop reduction due 3 to higher O concentration. 3 vulnerability can be understood by biochemical responses
