Assessment of ethylene diurea-induced protection in plants against ozone phytotoxicity.
Ethylene diurea (EDU) has been the most effective protectant used and has also served as a monitoring agent for assessing plant yield losses from 0 3 exposure, and indicates that EDU should be more widely used on 0 3 sensitive plants as a tool for biomonitoring of 0 3 concentrations. Expand
Investigating the response of tropical maize (Zea mays L.) cultivars against elevated levels of O3 at two developmental stages
Principal Component Analysis showed that both the cultivars showed differential response against O3 at two developmental stages, causing less translocation of assimilates to reproductive parts and thus affecting the final yield, and it is suggested that performance of HQPM1 (quality protein maize) was better than the DHM117 (non quality protein maize). Expand
Assessment of growth and yield losses in two Zea mays L. cultivars (quality protein maize and nonquality protein maize) under projected levels of ozone
Evaluated maize cultivars showed hormetic effect that is beneficial due to exposure of low doses of a toxicant, but at later stages, growth attributes were negatively affected by O3, and variable carbon allocation pattern particularly to husk leaves, foliar injury, and damage of photosynthetic proteins led to significant reductions in economic yield at higher O3 doses.

Cultivar specific variations in antioxidative defense system, genome and proteome of two tropical rice cultivars against ambient and elevated ozone.
Assessment of differential response if any in induction of antioxidative defense system, genome stability, leaf proteome, yield and quality of the product in both the test cultivars found reductions in yield and change in the quality of grains were noticed. Expand
Variability in defence mechanism operating in three wheat cultivars having different levels of sensitivity against elevated ozone
Abstract Wheat cultivars namely HD 2987 [ozone (O3) sensitive], PBW 502 (intermediately sensitive to O3) and Kharchiya 65 (O3 tolerant) were chosen on the basis of earlier study to investigate theExpand
Assessment of ozone toxicity among 14 Indian wheat cultivars under field conditions: growth and productivity
Path analysis approach showed that leaf area, plant biomass, stomatal conductance, net assimilation rate, and absolute growth rate were the most important variables influencing yield under O3 stress. Expand
Effect of elevated O3 on rhizospheric enzymatic activities of ozone sensitive and tolerant wheat cultivars
ABSTRACT Tropospheric ozone (O3) is considered harmful to agriculture production and soil community. Wheat cultivars HD 2987 (O3 sensitive) and Kharchiya 65 (O3 tolerant) were grown under ambient andExpand

There is a substantial spatial difference in O3 distribution at different places displaying variable O3 concentrations due to seasonal and geographical variations, and this review further recognizes the major information lacuna and also highlights future perspectives to get the grips with rising trend of ground level O3 pollution.

Responses of Zea mays L. cultivars ‘Buland’ and ‘Prakash’ to an antiozonant ethylene diurea grown under ambient and elevated levels of ozone
Increase in surface level of ozone (O3) in last 30 years is one of the major problems for global agriculture. Field experiment was conducted using open top chambers on two Indian maize cultivarsExpand
Inhibitive effect of chloroquine towards corrosion of mild steel in hydrochloric acid solution
Corrosion inhibition of mild steel (MS) by chloroquine (CQ) in 1 M HCl was investigated using weight loss, polarization, electrochemical impedance spectroscopy (EIS) and quantum chemical techniques.Expand
