“…1a, b) were remarkably reduced in all the growth phases under study. Our results are in consistent with the result of Tiyagi et al (2004) in chickpea and Mishra et al (2008Mishra et al ( , 2009 in Vigna unguiculata L. and Momordica charantia, respectively. Reduction in plant growth at higher concentration of chlorpyrifos could be due to the inhibition of activity of 4-hydroxyl phenyl pyruvate dioxygenase (HPPD) which in needed for growth and development of meristematic tissue which is confirmed with the result of Luscombe et al (1995) while treated maize and sugarcane with isoxaflutole.…”

Chlorpyrifos is a widely used broad-spectrum organophosphate insecticide in the agricultural practice. However, extensive use of this insecticide may lead to its accumulation in ecosystem, thus inducing the toxicity to crops and vegetables. To assess chlorpyrifos-induced toxicity in plants, we performed the experiment focusing on the growth and nitrogen metabolism of green gram plant (Vigna radiata L.). 20-days-old plants were subjected to chlorpyrifos at concentrations ranging from 0 to 1.5 mM through foliar spray in the field condition. Variation in root and shoot length, activities of nitrate reductase (NR) and content of nitrate, sugar, soluble amino acid and soluble protein were studied at preflowering (5 day after treatment, DAT), flowering (10 DAT) and postflowering (20 DAT) stages of plant development. Of the various concentrations of chlorpyrifos, 0.6 and 1.5 mM showed comparatively more severe toxicity to green gram plants by decreasing root and shoot length, nitrate, NR, soluble sugar and protein content where as at low concentration (0.3 mM) of chlorpyrifos proved stimulant for same parameter. Increase in soluble amino acid was observed in age and dose dependent manner. These results reflect strong parallelism between growth and biochemical activities of the model plant. Further lower dose of chlorpyrifos proved as stimulant where as at higher concentration proved detrimental for growth and nitrogen metabolism.

“…In concordance with our results, Bashir et al (2007) showed a similar increase of SOD activity after application of deltamethrin to Glycine max. Moreover, SOD activity increased in M. charantia after treatment by dimethoate (Mishra et al 2009). In other side, the electrophoretic analysis revealed the presence of 3 isoenzymes of SOD in tomato seedlings and leaves and just one isoenzyme in roots; generally, the isoenzymes in treated samples were more active compared to control.…”

Tomato (Lycopersicon esculentum Mill.) becomes one of the world's foremost vegetables, and its world production and consumption have increased fairly quickly. The capacity to induce oxidative stress in tomato plant, exposed to three xenobiotics such as alpha-cypermethrin, chlorpyriphos, and pirimicarb, was investigated by the evaluation of lipid peroxidation by measuring malondialdehyde (MDA) rate; also, we studied the response of tomato to this stress by assessing the response of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), ascorbate peroxidase (APX), glutathione-s-transferase (GST), and glutathione reductase (GR). The effect of the insecticides was observed using four concentrations (25, 50, 75, and 100%) for germinating seeds and only the recommended concentration in agriculture (100%) for growing plants. Our results show an important accumulation of MDA, demonstrating the increase of lipid peroxidation in consequence of the excessive reactive oxygen species (ROS) production due to insecticide treatment. In response to this oxidative stress in tomato seedlings and plants, the activities of antioxidant-enzyme system were generally enhanced. The electrophoretic analysis showed also the apparition of new isoenzymes as the case for CAT and POD.

“…Therefore, a preferential synthesis/ activation of this enzyme by Korean pine needles counteracts oxidative stress. The increase in the CAT, APX, and SOD activities are frequently observed under stressful conditions (Yazici et al 2007, Mishra et al 2009). Lu et al (2009) reported that UV-B and exogenous ABA stresses significantly increased the activities of CAT, SOD, and GPX.…”

The effect of supplementary UV-B radiation on Korean pine (Pinus koraiensis Sieb. et Zucc) was investigated. Compared with the control, the T1, T2, and T3 UV-B treatments increased by 1.40, 2.81, and 4.22 kJ m -2 d -1 , respectively. Gas-exchange parameters, photosynthetic pigment concentrations, contents of secondary metabolites, epicuticular wax, free radical, malondialdehyde (MDA), and the activities of antioxidant enzymes were determined after 40 d of exposure. The concentrations of chlorophyll (Chl) a, Chl b, total Chl, carotenoid (Car), and the ratio Chl a/b in the pine needles were in the following order: T1 > T2 > T3. Compared with the control, the contents of flavonoids and epicuticular wax significantly decreased in all levels of supplementary UV-B radiations (p<0.05). Moreover, the contents of hydrogen peroxide (H 2 O 2 ) and MDA significantly increased with the enhanced UV-B radiations (p<0.05). Korean pine can increase the catalase, ascorbate peroxidase, and superoxide dismutase activities to prevent oxidative stress by supplementary UV-B radiation. However, its defence mechanism is not efficient enough to prevent UV-Binduced damage.
