Use of ethylenediurea for assessing the impact of ozone on mung bean plants at a rural site in a dry tropical region of India

0

A field study was conducted to evaluate the usefulness of ethylenediurea (EDU) in assessing the impact of ozone (O3) on mung bean plants (Vigna radiata L Malviya Janpriya) grown in a rural area of a dry tropical region of India. Mean monthly O3 concentrations varied between 52.9-64.5 ppb. Significant reductions in growth, yield, soluble protein, pigments, and ascorbic acid in non-EDU-treated plants were observed when compared with EDU-treated plants. This clearly showed that EDU treatment provided protection against negative effect of O3 on mung bean and therefore can be effectively used as a tool to assess phytotoxic O3 concentrations in rural areas.
