A field study was conducted to evaluate the suitability of ethylene diurea (N-[2-(2-oxo-1-imidazolidinyl)ethyl]-N'-phenylurea; EDU) in assessing the impact of O3 on mung bean plants (Vigna radiata L. var. Malviya Jyoti) grown in suburban area of Allahabad city situated in a dry tropical region of India. EDU is a synthetic chemical having anti-ozonant property. Mean monthly O3 concentration varied between 64 and 69 microg m(-3) during the experimental period. In comparison to EDU-treated plants, non-EDU-treated plants showed significant reductions in plant growth and yield under ambient conditions. Significant favourable effects of EDU-application were observed with respect to photosynthetic pigments, soluble protein, ascorbic acid and phenol contents. EDU-treated plants maintained higher levels of pigments, protein and ascorbic acid in foliage as compared to non-EDU-treated ones. The study clearly demonstrated that EDU alleviates the unfavourable effects of O3 on mung bean plants, and therefore can be used as a tool to assess the growth and yield losses in areas having higher O3 concentrations.
开展了一项田间研究，以评估乙烯二脲（N-[2-(2-氧代-1-咪唑烷基)乙基]-N'-苯基脲；EDU）在评估臭氧对生长于印度干旱热带地区阿拉哈巴德市郊区的绿豆植株（绿豆品种Malviya Jyoti）的影响方面的适用性。EDU是一种具有抗臭氧特性的合成化学品。在实验期间，月平均臭氧浓度在64至69微克/立方米之间变化。与经EDU处理的植株相比，未经EDU处理的植株在环境条件下的生长和产量显著降低。在光合色素、可溶性蛋白、抗坏血酸和酚类含量方面观察到了EDU施用的显著有利影响。与未经EDU处理的植株相比，经EDU处理的植株叶片中的色素、蛋白质和抗坏血酸水平更高。该研究清楚地表明，EDU减轻了臭氧对绿豆植株的不利影响，因此可以用作评估臭氧浓度较高地区生长和产量损失的一种工具。
