Effectiveness of ethylene diurea in ameliorating ozone stress in blackgram varieties (<i>Vigna mungo</i> L.)

Tropospheric ozone, a phytotoxic air pollutant, has inadvertently increased since industrial era and its effect on agricultural crops gained urgent scientific attention. The present study aims to evaluate the response of blackgram varieties (Vigna mungo L.) exposed elevated ozone stress (100 ppb) with antiozonant (Ethylene diurea at 300 ppm). was conducted during two seasons effectiveness ethylene (EDU) explored in terms plant physiology, biochemistry, antioxidant enzymes, growth, yield spectral reflectance varieties. Ethylene ameliorates by increasing photosynthetic rate 40.78 37.21% season I 43.03 35.77% II for VBN3 VBN8, respectively, enzyme superoxide dismutase 24.31 19.42% 22.59 18.59% respectively. growth indices traits were significantly application EDU more pronounced sensitive cultivar (VBN3) compared tolerant (VBN8) one. Spectral reflectance, non-destructive study, further validates tropospheric Newly identified [R566, R573], [R564, R586] demonstrated greatest potential detecting sensitivity
